Abstract:
Summary Immiscible displacement of one fluid by another in porous media has practical applications when viscous oil is produced by water injection. A greater understanding of the flow patterns that evolve during such unstable displacements yields insights into improving predictive capability and increasing oil recovery. Immiscible multiphase displacement exhibits a wide range of behaviors depending on the relative magnitude of viscous, capillary, and gravity forces. Using flow-visualization images from forced-imbibition experiments carried out in etched-silicon micromodels, we show that the conventional Darcy-type modeling of fluid flux is not predictive under unstable, immiscible, forced-imbibition conditions at the scale of interest. When a less viscous fluid displaces a more viscous fluid at low capillary numbers, the displacement patterns show viscous instabilities in the form of fingers and local capillary control of interface movement. We show that such complex displacement patterns are well modeled using statistical theories. We derive a scaling model to describe quantitatively the functional forms for saturation, fractional flow, and capillary dispersion profiles using the self-similar characteristics inherent in the displacement patterns. For the specific range of flow rates (Nc ~ 10−7) and oil/water viscosity ratios (M ~ 8–400) considered in our experiments, both capillary and viscous forces are important, and the displacement pattern indicates fractal features. Results show that functional relations of the scaling model are in considerable agreement with our experimental data.

Abstract:
Zygomatic-maxillary (ZMC) complex fractures are a common consequence of facial trauma. In this retrospective study, we present a novel method of ZMC fracture pattern analysis, utilizing three-dimensional visualization of computed tomography (CT) images to record displacement of the malar eminence in a three-dimensional coordinate plane. The pattern of fracture was then correlated with treatment outcome. Facial CT scans were obtained from 29 patients with unilateral ZMC fractures and 30 subjects without fractures and analyzed. Briefly, displacement of the malar eminence (ME) on the fractured side was measured in medial-lateral (x), superior-inferior (y), and anterior-posterior (z) dimensions, as well as Euclidean distance, by comparison to ME location on the unfractured side. Baseline natural variance in asymmetry was accounted for by comparing ME location on the left and right sides in subjects without fractures. Patients who required open reduction and internal fixation (ORIF) to repair the ZMC fracture alone had significantly greater cumulative ME displacements than patients who did not require ORIF ( p = 0.02). Additionally, patients with a high fracture score of 3, 4, or 5 (assigned based on severity displacement in each dimension) had significantly higher rates of ORIF than patients with a low fracture score of 0, 1, or 2 ( p = 0.05). Severe displacement in one or more dimensions was associated with higher rates of ORIF than seen in patients with only neutral or mild displacements in all dimensions ( p = 0.05). Severe x displacement was most strongly correlated with surgical intervention ( p = 0.02). Overall, orbital floor repair was less strongly associated with most displacement measures than ZMC repair alone; however, patients requiring orbital floor repair had greater Euclidean ME displacements than patients who did not require orbital floor repair ( p = 0.02). Fracture severity, as determined by multiple parameters in this novel evaluation system, is associated with higher rates of ORIF in patients with unilateral ZMC fractures. Determination of ZMC fracture pattern may thus be informative when considering treatment options.

Abstract:
Through the use of nonlinear time-history analysis, the displacement patterns of bridges subjected to transverse seismic attack are investigated. The variables considered in the study consist of bridge geometry, superstructure stiffness, substructure strength and stiffness, abutment support conditions, and earthquake ground motion. A series of three inelastic displacement pattern scenarios were identified: (1) rigid body translation (2) rigid body translation with rotation, and (3) flexible pattern. A relative stiffness index that is a function of the superstructure and substructure stiffness was shown to be a key variable in determining the type of displacement pattern a bridge is likely to follow. The results described in this paper have significant implications for performance-based seismic design procedures such as direct displacement-based design (DDBD). If the displacement pattern for a bridge can be identified with significant confidence at the start of the design process, application of approaches such as DDBD can be simplified. However, if the characteristics of the bridge are such that prescribing a pattern at the start of the process is not feasible, then an alternative approach must be employed for DDBD to proceed. Of the three displacement pattern scenarios defined in this paper, the first two require minimal effort in the design. For the third scenario, an iterative algorithm is proposed. Lastly, as a means for verification and demonstration, a series of bridges with various configurations was designed using DDBD for rigid body translation and flexible pattern scenarios. The designs for the flexible scenario showed good agreement with selected target profiles for bridges with up to five spans.

Abstract:
Displacement patterns of rib fractures (RF) and their association with thoracic coinjuries and outcomes are unknown. This is a retrospective review of adult patients with blunt closed RF who underwent chest CT at a Level I trauma center (2007–2012). Displacement patterns of RF were compared among the three-dimensional planes using CT images. An analysis of receiver operating characteristic (ROC) curves was performed to identify displacements in each plane most strongly associated with chest coinjuries. Univariate analysis was used to find association of displaced RF with hospital course and outcome. There were 1127 RF (245 patients, most in ribs 3–9, 45 per cent displaced). Axial displacement was the most common, with odds ratios 7.20 and 2.13 compared with cranio-caudal, and impaction-separation (along rib axis) movement, respectively. Axial displacement thresholds performed well with hemothorax (2.8 mm, ROC = 0.74), pneumothorax (2.6 mm, ROC = 0.70), hemopneumothorax (3.1 mm, ROC = 0.77), flail chest (3.4 mm, ROC = 0.80), and chest tube placement (2.8 mm, ROC = 0.75). RF displacement was associated with increased days on mechanical ventilation and hospital length of stay. In conclusion, even minimal RF displacement is associated with increased risk of chest coinjuries and chest tube placement, and displacements correlated with increased days on mechanical ventilation and hospital length of stay. Future studies are required to investigate these associations, especially in relationship to the indications for rib plating.

Full text
Abstract:
The threshold of sensitivity to movement could be governed by mechanisms that are sensitive either to change in spatial position, or directly to the movement itself. The use of spatially complex patterns (random-dot patterns) has been suggested to eliminate the former strategy allowing examination of the movement detecting mechanisms in isolation. By means of such a technique, thresholds for directional judgements were determined for patterns which underwent either a simple displacement or a shearing displacement. Thresholds for shearing motion were found to be around one half of those for simple motion, suggesting that relative, rather than absolute, motion governs performance for small displacements. This contrasts with previous experiments which showed that absolute motion governs performance for much larger displacements.

Abstract:
Purpose This study sought to determine decoupled tongue and jaw displacement changes and their specific contributions to acoustic vowel contrast changes during slow, loud, and clear speech. Method Twenty typical talkers repeated “see a kite again” 5 times in 4 speech conditions (typical, slow, loud, clear). Speech kinematics were recorded using 3-dimensional electromagnetic articulography. Tongue composite displacement, decoupled tongue displacement, and jaw displacement during /ai/, as well as the distance between /a/ and /i/ in the F1–F2 vowel space, were examined during the diphthong /ai/ in “kite.” Results Displacements significantly increased during all 3 speech modifications. However, jaw displacements increased significantly more during clear speech than during loud and slow speech, whereas decoupled tongue displacements increased significantly more during slow speech than during clear and loud speech. In addition, decoupled tongue displacements increased significantly more during clear speech than during loud speech. Increases in acoustic vowel contrast tended to be larger during slow speech than during clear speech and were predominantly tongue-driven, whereas those during clear speech were fairly equally accounted for by changes in decoupled tongue and jaw displacements. Increases in acoustic vowel contrast during loud speech were smallest and were predominantly tongue-driven, particularly in men. Conclusions Findings suggest that task-specific patterns of decoupled tongue and jaw displacement change and task-specific patterns of decoupled tongue and jaw contributions to vowel acoustic change across these speech modifications. Clinical implications are discussed.

Abstract:
Contemporary population displacement trends are impacting cities located in developing countries in unprecedented ways. This scenario is reflected in the Mexican border town of Tijuana, which from May 2016 to January of 2017, experienced the massive arrival of Haitians seeking asylum in the United States. My thesis addresses the Haitians’ patterns of displacement and the actors involved in their migratory processes including governmental and non-governmental authorities in Mexico and the United States. Because of the complexity of displacement today, I argue that in order to comprehend patterns and responses to displacement, it is necessary to use a multi-scalar global perspective that addresses the relationship between time and space as well as the relationship between politics and power. Furthermore, I argue that the Haitians' arrival to the U.S.-Mexico border is an illustration of crisis migration, which views displacement as the result of a combination of social, political, economic, and environmental crises.

Abstract:
After the excavation of a cut slope ongoing deformations on the slope surface can often be measured. These deformations can be induced due to various processes and can also be used as an indicator of slope stability. If the reasons for the deformations are known, selective stabilization methods can help to decelerate, or stop, the movements. The potential for the recognition of displacement patterns in excavated slopes is studied in this dissertation. In the laboratory, the analysis of displacement patterns due to various processes is difficult as identical initial test conditions can hardly be reproduced. Furthermore, measurements of displacements can only be conducted to a limited degree. Therefore, numerical calculations using the finite element method were applied to simulate excavation processes and analyse the displacements. In addition, a suitable mathematical model has to be used to represent the stress-strain behaviour during the unloading process. Three different advanced constitutive soil models were chosen to calculate an excavation process of an idealized slope assuming drained conditions: - elasto-plastic Modified-Cam-Clay model - rate-independent hypoplastic model according to Masin - rate-dependent visco-hypoplastic model according to Niemunis Before conducting the excavation simulation, the soil parameters of the constitutive models were calibrated by means of numerical element tests, depicting the stress paths of conventional laboratory tests. Within the literature, those conventional laboratory tests are recommended for the determination of parameters for the constitutive models. A parameter set for the visco-hypoplastic model was chosen from literature. The parameters were adapted for the remaining models. Thus, all three models predicted approximately the same stress-strain behaviour during conventional laboratory tests. Despite the correlations during the element tests, the constitutive models predicted different displacements during the calculation of the excavation of an idealized slope under drained conditions. Thereupon, load-controlled triaxial compression tests were conducted reproducing the characteristic stress paths during an excavation process. At the same time, numerical calculations were carried out to reproduce the triaxial compression tests, and the measured and calculated displacement behaviour was compared. Different processes such as pure unloading due to excavation, excavation in overconsolidated soil, excavation coupled with consolidation, excavation coupled with previous ground water lowering and consolidation as well as the influence of creep effects were considered in the analysis of the displacement patterns during an excavation. It can be stated that the evaluation of displacements and changes in displacements in a single point on the slope surface cannot provide sufficient information about a certain physical process. Only the combination of displacement paths at different survey points will lead to a reliable conclusion. Thus, representative displacement patterns for different processes are recognizable during and after the excavation, which can be used for the identification. During the numerical simulation of an in-situ model test, where a slope was brought to failure by excavation, the calculated displacements were analysed for identifiable displacement patterns. It can be stated that despite different slope systems, consistencies were found within characteristic survey points. These points can be used to identify patterns within the displacement contours.

Abstract:
Master of Science<br>Department of Civil Engineering<br>Asad Esmaeily<br>Performance-based building design is a necessity in geographic locations where buildings are susceptible to large earthquakes and high winds. This design method requires an analysis of the performance of the structural system with loadings and deflections caused by earthquakes and wind. Current design codes include the load intensity in analysis procedures, but do not consider the effect of load pattern in the performance analysis of reinforced concrete columns. Because a thorough analysis must take into consideration load pattern and load intensity, computer software is ideal to analyze these systems. A computer program was originally developed by Esmaeily (USC_RC), and was revised later to be renamed (KSU_RC) in order to make the analysis of concrete column performance accurate, yet simple for design purposes. This analytical tool used analytical methods and material models, verified against experimental data, to accurately predict the performance of reinforced concrete columns under various loading conditions, including any pattern in lateral direction and independently variable axial load. However, the program was limited to circular, rectangular, hollow circular and rectangular sections and uniaxial lateral curvature and displacement. The next generation of the program, KSU RC 2.0, was developed to overcome the aforesaid limitations.

Abstract:
This thesis is concerned with modeling geometric patterns. Specifically, a clear and practical definition for regular patterns is proposed. Based on this definition, this thesis proposes the following modeling setting to describe the semantic transfer of a model between various forms of pattern regularity: (1) recognition or identification of patterns in digital models of 3D assemblies and scenes, (2) pattern regularization, (3) pattern modification and editing by varying the repetition parameters, and (4) establishing exceptions (designed irregularities) in regular patterns. In line with this setting, this thesis describes a representation and approach for designing and editing hierarchical assemblies based on grouped, nested, and recursively nested patterns. Based on this representation, this thesis presents the OCTOR approach for specifying, recording, and producing exceptions in regular patterns. To support editing of free-form shape patterns on surfaces, this thesis also presents the imprint-mapping approach which can be used to identify, extract, process, and apply relief features on surfaces. Pattern regularization, modification, and exceptions are addressed for the case of relief features on surfaces.

The aim of this work was to evaluate cattle pattern displament on kikuiu-grass submitted to different heights and the same level of defoliation of 50%. The experiment was carried out at CAV/UDESC during April and May 2013. The experimental design was a complete randomized block design with three replications and four treatments. The treatments were four pre-grazing heights: 25, 20, 15 and 10 centimeters associated which were associated with a level of defoliation of 50%. Animals stand longer on feeding stations in 20 and 25 cm swards during the initial stage of grazing without differences on the final phase of grazings down. At the early stage, on the lower pasture height (10 cm) the animals walked more and moved more quickly when compared to those managed at higher swards heights (5,25 e 4,0, respectively). There was no difference during the final stage of grazings process. The bite number in each feeding station had a linear reduction with the increase in sward height during the initial phase, being minor on the 25 cm height (27 bites.feeding station-1), with no differences at the final stage. Bite rate (bites. min-1) also presented a linear response by reducing according the increase in pasture height, from 42,02 to 35,18 bites.min-1 in pastures with 10 and 25 cm, respectively. During the initial phase of the grazing down the animals presented diferences in displacement patterns, suggesting that swards heights of 20 to 25 cm (in kikuygrass) present better conditions to foraging search. At the final phase, the animals did not present differences among treatments, suggesting that on using 50% of the grazing down is already over the limit when the objective is to minimize forage searching<br>O manejo sustentável das pastagens está ganhando cada vez mais espaço na pesquisa mundial, visando maior desempenho animal aliado à preservação dos recursos naturais. O objetivo deste trabalho foi avaliar os padrões de deslocamento de bovinos em pastos de capim-quicuio, submetidos a diferentes alturas de entrada e mesma severidade de desfolhação de 50%. O experimento foi realizado no setor de bovinocultura leiteira do CAV/UDESC, durante os meses de abril e maio de 2013. O delineamento experimental foi em blocos completos casualizados com três repetições e quatro tratamentos. Os tratamentos eram quatro alturas em pré-pastejo: 25, 20, 15 e 10 cm, associados com uma severidade de desfolhação de 50% destas alturas. O maior tempo de permanência dos animais nas estações alimentares foi encontrado nos pastos mais altos, com 20 e 25 cm de altura, na fase inicial de rebaixamento dos pastos, sem diferenças na fase final do rebaixamento. Os animais caminharam mais (P.min-1) e com maior rapidez (passos entre estações) nos pastos mais baixos (10 cm), durante a fase inicial de rebaixamento destes. Já na fase final não foram observadas alterações. O número de bocados em cada estação alimentar na fase inicial do rebaixamento apresentou uma redução linear com o aumento da altura, sendo menor na altura de 25 cm (27,02), permanecendo sem diferenças na fase final. A taxa de bocados (bocados. min-1) também apresentou uma resposta linear, reduzindo conforme o aumento na altura dos pastos, de 42,02 para 35,18 bocados.min-1, nos pastos com 10 e 25cm, respectivamente. Os animais na fase inicial de rebaixamento dos pastos apresentaram diferenças nos padrões de deslocamento, indicando que alturas de dossel de 20 e 25 cm (em pastos de capim-quicuiu) apresentam melhores condições ao processo de forrageamento. Já na fase final, os animais não apresentaram diferenças entre os tratamentos, sugerindo que utilizando a faixa de 50% de rebaixamento dos pastos os animais já encontram dificuldades no processo de busca por forragem, independente de metas de alturas em pré-pastejo

Abstract:
Although the study of the interaction of acoustic and elastic waves with periodic surfaces and structures has a rich history dating back to Lord Rayleigh, it has recently been attracting new research efforts due to its value in the study of phononic crystals and in methods for ultrasonic non-destructive evaluation (NDE). The objective of the research described in this thesis is to provide new numerical and experimental tools capable of capturing important features that occur due to the diffraction of ultrasound on periodic solid surfaces. This thesis is divided into four main parts. First, the Rayleigh-Fourier (R-F) method will be used to simulate diffracted fields generated by structures containing multiple periodic surfaces and/or multiple solid layers. The second part of this thesis examines diffraction effects and compares ultrasonic NDE techniques for surfaces with imperfect periodicities. The third portion of this thesis focuses on one unusual phenomenon that has been observed on periodic surfaces, namely the lateral backward displacement of a bounded ultrasonic beam along the surface. This effect is currently understood to occur due to backward propagating surface waves that result from diffraction and mode conversion on the surface. The fourth and final part of this thesis describes the diffraction of bulk ultrasonic waves that can occur on the surfaces of phononic crystals.

Abstract:
Gentrification is reshaping cities worldwide, resulting in seductive spaces and exclusive communities that aspire to innovation, creativity, sustainability, and technological sophistication. Gentrification is also contributing to growing social-spatial division and urban inequality and precarity. In a time of escalating housing crisis, unaffordable cities, and racial tension, scholars speak of eco-gentrification, techno-gentrification, super-gentrification, and planetary gentrification to describe the different forms and scales of involuntary displacement occurring in vulnerable communities in response to current patterns of development and the hype-driven discourses of the creative city, smart city, millennial city, and sustainable city. In this context, how do contemporary creative practices in art, architecture, and related fields help to produce or resist gentrification? What does gentrification look and feel like in specific sites and communities around the globe, and how is that appearance or feeling implicated in promoting stylized renewal to a privileged public? In what ways do the aesthetics of gentrification express contested conditions of migration and mobility? Addressing these questions, this book examines the relationship between aesthetics and gentrification in contemporary cities from multiple, comparative, global, and transnational perspectives.

Abstract:
Deportation and migration were formative for ancient Judaism and seminal for its literature. Dislocation, whether conceived of as forced or voluntary, influenced Israel’s recollection of her more distant past. Early pre-exilic narratives of Israel’s beginnings were redacted during and in response to Israel’s experience of exile, so that, for example, earlier Abraham and Joseph traditions were reshaped drawing on the realities of the Babylonian exile and the related Diaspora; these reworked traditions, in turn, informed narratives, such as Esther and Daniel, that took exile and diaspora as their explicit subject. The stories of Israel’s origins and its accounts of post-exilic and diasporic existence exerted a reciprocal influence on each other; and thus Israelite history came to be narrated as a series of exiles and returns, in which current dislocations were understood in terms of primeval patterns, and ancestral stories were revised in light of current dislocations.

Abstract:
The Middle East is currently facing one of its most critical migration challenges, as the region has become the simultaneous producer of and host to the world’s largest population of displaced people. As a result of ongoing conflicts, particularly in Syria, Libya, Iraq, and Yemen, there have been sharp increases in the numbers of the internally displaced, forced migrants, refugees, and asylum-seekers. Despite the burgeoning degree of policy interest and heated public discourse on the impact of these refugees on European states, most of these dislocated populations are living within the borders of the Middle East.This volume is the outcome of a grants-based project to support in-depth, empirically based examinations of mobility and displacement within the Middle East and to gain a fuller understanding of the forms, causes, dimensions, patterns, and effects of migration, both voluntary and forced. As the following chapters in this volume will demonstrate, through this series of case studies we are seeking to broaden our understanding of the population movements that are seen in the Middle East and hope to emphasize that regional migration is a complex, widespread, and persistent phenomenon in the region, best studied from a multidisciplinary perspective. This volume explores the conditions, causes, and consequences of ongoing population displacements in the Middle East. In doing so, it also serves as a lens to better understand some of the profound social, economic, and political dynamics at work across the region.

Abstract:
This chapter explores the relationship between migration, displacement, and the Underground Railroad movement. More specifically, it considers the processes of community building and the causes of migration that led Blacks to live where they did and to flee when they had to. It shows how migration became a means of escape from slavery, first by discussing maroon settlements that functioned as the African diaspora's first communities for free Blacks and began the progression to the Underground Railroad. It then explains how Black community formation and the Underground Railroad shifted between constant migration and displacement that began with the Middle Passage, and how emigration and colonization schemes of the pre-Civil War abolitionist era influenced displacement and migration patterns. This analysis looks at African American migration from a new perspective by sifting through the range of ways in which people of color entered into and interacted with their surroundings. It suggests that migration, both voluntary and forced, courses through the Black experience.

Abstract:
AbstractThis chapter discusses the creeping crisis of rising human displacement induced by environmental degradation and natural catastrophes. Sea-level rise, droughts, and the increased occurrence of hurricanes and floods already have, and increasingly will have, drastic effects on migration patterns. Climate-induced displacement already outnumbers displacement from war or violence. Nation states and the international community have consistently failed to properly address this phenomenon. Only recently has political attention begun to increase. This chapter argues that our understanding of climate-induced migration can be improved with the help of the creeping crisis concept. In addition, climate-induced migration may provide insights to the underlying mechanisms of creeping crises. More to the point, this chapter explores the rise and fall of political attention in this case, offers insights on what lies behind this and reflects upon the broader implications for the literature on creeping crises.

Abstract:
AbstractLGBTQ neighborhoods face change. Planning for these neighborhoods requires data about LGBTQ residential concentration. Some analysts have used US Census same-sex partner data to make judgments about LGBTQ neighborhoods. Two agency actions make this reliance problematic. The US Census was required to enforce the Defense of Marriage Act and reassigned some LGBTQ responses in a heteronormal way. The Census also assigned sex based upon patterns of names. These US Census actions of gay removal and sex assignment to datasets raise questions about the usefulness of the partner dataset. A queer reading of the census may give a better representation of neighborhood development and decline. Data are developed for four queer neighborhoods: the West Village in New York City, Center City Philadelphia, Midtown Atlanta, and Midtown Kansas City. The results show that queer attributes of these areas grew to about 1990. Some queer attributes may have declined some from their peak. The results raise questions about social surveys, the closet, and the direction of LBGTQ neighborhoods in the twenty-first century. LGBTQ displacement has occurred.

Abstract:
Articular cartilage and surrounding soft tissues in the knee are important to normal joint function. Osteoarthritis (OA) is highly prevalent in the United States [1] and features precocious degeneration of articular cartilage. Effective OA treatments require the ability to detect early degeneration, including mechanical and biochemical changes. Magnetic resonance imaging has shown promise for the detection of early degenerative changes, including various quantitative MRI techniques [2]. Displacement-encoded MRI has the ability to detect changes in mechanical behavior, and such techniques have previously been used in cartilage explants [3] and intact juvenile animal joints [4]. However, the authors are aware of no studies with displacement-encoded MRI of human articular cartilage. Tissue-level displacement patterns could be key to revealing early degeneration in articular cartilage. This study demonstrates for the first time displacement encoding with stimulated echoes (DENSE) in an adult human tibiofemoral joint.

Abstract:
Religious identity is critically important to consider in assessing patterns of displacement and the dynamics of conflict and peace-building, as well as programmatic and policy responses to humanitarian crises. Conflicts are frequently driven by discrimination and generate massive numbers of refugees and internally displaced persons (IDPs) as they flee from persecution and violence, whilst individuals or groups may be targeted for their identity or face insecurity during community activities. As a result, the relationship between diversity, inclusivity, and interdependence is key to developing approaches that address intersecting forms of insecurity experienced by religious minorities. This paper reviews current thinking and policy directions in understanding religious inequalities in humanitarian contexts and asks the following questions: 1) What are the implications of programming that is blind to religious inequalities? 2) How can humanitarian actors incorporate sensitivity to religious difference and persecution in their programming, and what are the challenges of doing so?

A STUDY OF COLLAPSE SUSCEPTIBILITY AND RESISTANCE OF LOADED CABLE-SUPPORTED PIPE STRUCTURE SUBJECT TO A SUDDEN BREAK OF CABLE MEMBER. The Hong Kong Institute of Steel Construction, 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.7.

Full text
Abstract:
Cable-supported pipe system (CSPS) provides a suitable system of structure for meeting the stringent structural requirements of pipeline bridges. However, due to a composite action of cable with truss and pipe members, the sudden failure of its structural member may lead to undesired vibratory response and collapse. The occurrence of a sudden break of the CSPS structural member is characterized by spontaneous dynamics and internal force rearrangement. The present study aims to investigate parametrically the collapse susceptibility and resistance of scaled down CSPS model in the event of a sudden break of the cable member by combined experimental and numerical procedures. The displacement of the structure, the pattern of internal force rearrangement, and dynamic responses were comparatively evaluated. Experimental results depict imminent cable failure under load and attendant dynamic response, but without a total collapse of the CSPS structure. Critical members causing large dynamic response amplitudes were identified and the mitigation of collapse was evaluated. Dynamic increasing factor (DIF) methods was utilized for the evaluation of the dynamic response of the sudden cable break resulting from the pattern of responses between the cable members and the rest of the CSPS structure. Comparison with provisions in other studies shows higher values DIF of the CSPS cable members which led to proposed evaluation using dynamic factor (DF). Thus, the dynamic factors for the sudden break of various cable members along the span and the errors were also estimated considering the parametric of design variables which will enable easy utilization during the structural process of CSPS.
