Abstract:

The California Tree Failure Report Program database was established in 1987 to collect data on tree branch, trunk, and root breakage or uprooting. The database for the CTFRP is compiled from failure evaluation reports filled out by statewide cooperating arborists, tree assessors, and other horticultural professionals. Compilation of 186 reports for Monterey pine (Pinus radiata) has permitted development of a "failure profile" -a characterization of failure location, structural defects, decay, climatic conditions, and other factors associated with structural failure of Monterey pine. Monterey pine was found to be particularly failure prone compared to other tree species in Golden Gate Park, San Francisco, CA. Close to 60% of Monterey pine failures reported in the CTFRP database were limb failures, rather than trunk or root failures, and most of these were considered to be heavy lateral limbs - a structural defect. The majority of limb breakage occurred away from, rather than at the point of attachment, suggesting a wood strength problem. Decay was notfrequently associated with Monterey pine failures at any location on the tree. Tree spacing, nutrition, and genetic strain are likely to be major factors influencing heavy lateral limb development. Closer tree spacing, low nitrogen input, and genetic selection offer hope for reducing Monterey pine branch failure.

Abstract:

Abstract This column suggests that developing 3D structural models as tools for observing and exploring failures in the virtual domain could prove instrumental in avoiding failure without committing hardware. Likewise, instead of building hardware to systematically evaluate failures in the presence of random effects, virtualization through a 3D model could provide a completely user-defined environment for conducting controlled experiments. In such a virtual environment, systematic and random behaviors can be introduced and parsed to provide greater clarity in the search for root causes of failure.

Abstract:

Structural failures of bulk carriers continue at a steady and unacceptable rate, claiming some 150 lives per year. This paper explains why bulk carriers are vulnerable to structural failure either because side shell plating falls out allowing ingress of seawater or the deck cracks open. Inadequate detail design, material without guaranteed fracture toughness and limitations of current inspection programmes are identified as fundamental weaknesses. The paper includes important information from a case study of six oil bulk ore carriers prone to deck cracking. One of the group of six which sank in 1980 was traced 4200 metres down on the floor of the Pacific Ocean in June 1994 and the results of this initial search are reviewed. There is a genuine need to go back to basics. Designing from first principles to determine local stresses is an important first step rather than the current use of prescriptive rules. All subsequent steps in bulk carrier construction and maintenance should be subject to a penetrating review.

Abstract:

A method based on structural modelling is developed for failure evaluation and analysis of mechatronics-based production systems. Majority of the elements in production systems are mechatronics-based, which includes various elements such as; electrical, electronic and mechanical. Each of these may have different failure types that may be interdependence/interactive. The reliability of the system mainly depends on how well the failures are taken care of during design stage. In general, individual failures are generalized into probable failure modes and early identification of these helps to reduce their probability. However, consideration of failures and their interdependence / interactions will help to evaluate and analyse the failures of complicated systems in an efficient and effective manner and increase the inherent system reliability. The system structure modeling helps in this regard. Digraph model, in conjunction with matrix method, is employed for failure evaluation and analysis of a mechatronics-based production system based on its structure.

Abstract:

The problem of the structural failures is inextricably linked with the construction industry. A structural failure can be defined as the unintentional, violent destruction of a building object or its part, as well as structural elements of scaffolding, forming elements, sheet piling and excavation linings. Structural failures always entail financial and environmental losses that cause a big problem for companies. The analysis of the structural failures allows to indicate the causes that led to them, but also to introduce actions to help avoid them or decrease their appearance in the future. From the point of view of sustainability risk, human life, corporate responsibility, but also possible financial penalties, it is a very important element of the business process management in an enterprise. In the paper the structural failures occurring in Poland in 2015–2019 were analyzed based on data from the General Office of Building Control (GUNB). They are divided into two categories: caused by random factors and resulting from human error. Failures caused by human error were divided into those related to construction, used material and building operation (exploitation). The structural failures occurring during construction works, e.g., construction, renovation, demolition works, as well as in existing facilities, e.g., during the use of the facility but also in facilities excluded from use, were analyzed. Then, the individual causes of the structural failures were analyzed in terms of repeatability in each category. The risk priority number was calculated for the causes in the group “random events” and nine causes related to “human error”. Actions aimed at reducing the risk of future failures were proposed. The results of the analysis provide conclusions that constitute input data for the improvement of both the processes themselves and the procedures for design, construction and exploitation, or methods and frequency of inspections.

Abstract:

One of the major challenges involved in the use of ceramic materials in advanced vehicular heat engines is ensuring adequate strength and durability. This Department of Energy supported activity has developed methodologies to predict the structural behavior of ceramic components. The effort involved the characterization of injection-molded and hot isostatic pressed PY6 silicon nitride and the development of analytical life prediction techniques. Three failure modes are addressed: fast fracture, slow crack growth, and creep rupture. The technique deals with surface as well as internal component failures. The life prediction methodologies for fast fracture and slow crack growth have been verified using two types of confirmatory specimens: (1) flat circular disks subjected to bending stresses, and (2) high-speed rotating spin disks. Correlation was achieved for a variety of test conditions and failure mechanisms. The predictions associated with surface failures proved to be optimistic, requiring re-evaluation of the components’ initial fast fracture strength. Correlation was achieved for the spin disks that failed in fast fracture from internal flaws. Time-dependent, elevated-temperature spin disk failures were also successfully predicted.

Abstract:

Fibre reinforced polymers (FRP) offer a high potential to reduce kinetic energy. As a consequence of this, fibre reinforced polymers often have a higher risk of being exposed to impact loads. The knowledge of the mechanisms and of the material loading during and shortly after an impact load is essential for an ‘impact-load-monitoring-system’ to predict possible structural failures. Especially a prognosis of structural failures caused by – often unrecognized - barely visible impacts is an important factor. Primary impact damages often leads to a sudden structural failure. These unheralded failures seems to be one of the most important problems in product development for the aircraft industry. By measuring the structural response at several discrete measurement points an impact can be detected, reconstructed and also rated.

Abstract:

This paper analyzes two tailings dam databases and recent failures to assess the local and global failure rates of upstream, downstream, and centerline raised tailings dams. Since 2000, the failure rate for all three raising methods has decreased except in Brazil, which helps explain the recent Brazilian regulations banning upstream raising. However, the failure rates also show that the downstream and centerline raising methods of tailings dams are not immune to failure, so, if mining continues, one of these three raising methods will be used, and all have been involved in prior failures. The paper also presents data on failure mechanisms, showing that slope stability, earthquakes, and overtopping are the three primary causes of tailings dam failures. To continue decreasing the failure rate of tailings dams, the following features and practices should be used in all types of tailings dams: drainage systems, engineering analyses, instrumentation, monitoring, inspection, and qualified external peer review to further reduce the failure rates, especially in Brazil. Finally, a section containing data on release volume as a function of dam height and total storage volume is presented.

Abstract:

The spatial and temporal patterns of water distribution pipe failure in the City of Winnipeg are examined. The failures are shown to be strongly clustered in space, where 22% of the total failures examined occur within 1 m of another failure and 46% occur within 20 m of another failure. A strong temporal clustering is also apparent, with 42% of all failures that occur within 1 m of another found also to occur within 1 day of the initial failure in the group. An exponential decrease in the marginal rates of failure with respect to both the temporal and spatial interval parameter is also observed. Earlier failures in a particular location appear to be an important key to assessing potential failures in that vicinity. These results suggest that a fruitful area for further examination for the reduction of failure rates is the change in the ground conditions resulting from an initial leak and its subsequent repair. Key words: failures, groupings, marginal rates, pipes, space, time, water distribution, Winnipeg.

Abstract:

Many structural failures in precast concrete buildings are initiated by connection failures. To avoid such failures, the connections should have enough strength to join the reinforcement bars between precast concrete panels. This paper presents the structural performance and behaviour of a proposed splice sleeve connection using generic steel pipe. The connection consisted of steel bars with tapered nuts confined in grouted steel pipes. The connections were subjected to increasing axial tension until failure. The results show that the use of smaller pipes gives better confinement effects and provide higher bond strength. A short embedment length of about 10 times rebar diameter is able to provide full tensile strength of the connected rebars. As compared to long embedment length of conventional lapping of steel bars, the proposed connection is able to provide structural continuity with short embedment length.

Abstract:

Man used to live in huts that were built with materials found in abundance in nature. They were able to construct their huts in safe locations that were not harmed by natural disasters. If something went wrong, they could fix it with the cheapest materials found in nature. However, as the population grows and new building materials are developed, it is becoming increasingly vital to understand structural weaknesses in buildings and the remedial steps that must be taken. Engineering failures are caused by the deterioration of various building materials over time, for a variety of reasons. To understand the problem and come up with a solution, it is important to be aware of the many things that make things get worse. Here this article highlights about the structural failures and remedial measures.

Abstract:

With structural reliability assessment as the scenario, a structural part made of foam material was treated as a series k-out-of-n system. The strength random variable of a large-size part was characterized by the strength random variables of virtual elements with certain size, as well as the number of the elements determined by part size. Specially, the statistical dependence among element failures was expounded with respect to the virtual elements. A series k-out-of-n system failure probability model was presented, and the failure probability of a structural part of foam material was described in terms of the size parameters of the part in two dimensions: the number of elements in width direction and that in length direction. It was shown that strong dependence among element failures exists, the failure probability of a large-size part will approaches to an upper bound with the increase in part length.

Abstract:

The stability of rock slopes is often guided significantly by the structural geology of the rocks composing the slope. In this work, we analysed the influences of structural characteristics, and of their seismic responses, on large and deep-seated rock slope failure development. The study was focused on the Tamins and Fernpass rockslides in the European Alps and on the Balta and Eagle’s Lake rockslides in the southeastern Carpathians. These case studies were compared with catastrophic rock slope failures with ascertained or very likely seismic origin in the Tien Shan Mountains. The main goals was to identify indicators for seismically-induced rock slope failures based on the source zone rock structures and failure scar geometry. We present examples of failures in anti-dip slopes and along-strike rock structures that were potentially (or partially) caused by seismic triggering, and we also considered a series of mixed structural types, which are more difficult to interpret conclusively. Our morpho-structural study was supported by distinct element numerical modelling that showed that seismic shaking typically induces deep-seated deformation in initially “stable” rock slopes. In addition, for failures partially triggered by dynamic shaking, these studies can help identify the contribution of the seismic factor to slope instability. The identification of the partial seismic origin on the basis of the dynamic response of rock structures can be particularly interesting for case histories in less seismically active mountain regions (in comparison with the Andes, Tien Shan, Pamirs), such as in the European Alps and the Carpathian Mountains.

Abstract:

This paper aims to investigate the structural behavior of digitally fabricated thin-walled timber sections with edge connectivity provided by integral mechanical press-fit joints. Experimental, numerical, and analytical investigations have been developed to accurately characterize the press-fit section behavior and their failure modes. Plywood fiber orientation, material thickness, and connection tightness are considered as potential factors that may affect the performance of the press-fit jointing system. Experimental testing of square hollow sections (SHSs) under uniaxial compressive loading showed failure of sections through both conventional crushing and novel pop-off bifurcation failures. Pop-off buckling behaviors were shown to be governed by the integral joint transverse stiffness and its magnitude relative to a critical edge stiffness value. Columns with joint transverse stiffness value less than the critical edge stiffness value exhibited pop-off failures. These joint stiffness values were obtained from testing of unloaded joints and were used to obtain accurate predictions of column failure modes. Joint stiffness values for loaded joints were then predicted with an interpolation model mapping axial strain to a tighter connection tolerance and these were used to obtain accurate estimations for column failure load in most of the tested column types. Comparative investigations showed thin-walled sections with integral joints only to be capable of matching the compressive capacities of glued sections, for instances where crushing governed. Similarly, the weight-specific compressive capacity of timber sections was found to be comparable to thin-walled steel sections when crushing governs.

Abstract:

The growing use of gas-fired power generators and electricity-driven gas compressors and storage has increased the interdependence between electric power infrastructure and natural gas infrastructure. However, the increasing interdependence may spread the failures from one system to the other, causing subsequent failures in an integrated power and gas system (IPGS). This paper investigates the structural vulnerability of a realistic IPGS based on complex network theory. Different from the existing works with a focus on the static vulnerability analysis for an IPGS, this paper considers both static and dynamic vulnerability analysis. The former focuses on vulnerability analysis under random and selective failures without flow redistribution, while the latter concentrates on vulnerability analysis under cascading failures caused by flow redistribution. Also, different from the existing works with a focus on the IPGS as a whole, we not only analyze the vulnerability of the IPGS but also analyze the vulnerability of the power subsystem (PS) and gas subsystem (GS), in order to understand how the vulnerability of the IPGS is affected by its PS and GS. The analysis results show that (1) if the PS and GS are more susceptible to cascading failures than selective and random failures, the IPGS as a whole is also more vulnerable to cascading failures. (2) There are different dominant factors affecting the IPGS vulnerability under cascading failures and selective failures. Under cascading failures, the GS has a more significant impact on the IPGS vulnerability; under selective failures, the PS has a more important impact on the IPGS vulnerability. (3) The IPGS is more vulnerable to failures on the critical nodes, which are identified from the IPGS as a whole rather than from the individual PS or GS. The results provide insights into the design and planning of IPGSs to improve their overall reliability.

Abstract:

The purpose of the work is to develop a method of estimating the probability of failure-free operation of transport systems on the basis of their logical structural diagrams of reliability, which makes it possible to evaluate their dependence on the level of probability and the number of elements and to predict and prevent failure of a chain or system as a whole. The theoretical substantiation of reliability estimation of functioning of transport systems using logical structural schemes of reliability is given and it is revealed that their construction is based on the analysis of consequences of failures of individual elements. Properties of elements and systems for their working and inoperable states are highlighted. The formulas for calculating the probability of failure-free operation and failure of the chain or the transport system as a whole, as well as their time to failure. The dependence of the probability of failure-free operation of the transport system on the level of probability and the number of its elements is shown. Cases of serial and parallel connection of elements in the transport system chain are considered. Methods of calculation of structural reliability schemes are presented and formulas are used for estimating the probability of trouble-free operation of technical and transport systems, as well as the probability of their failures. Dependencies of reliability indicators on number of elements are constructed. It shows the reliability estimation of bridged structural diagrams using the methods of minimum paths, minimum cross sections, transformation of the connection of elements "triangle" - "asterisk", a key element. It is found that complex technical and transport systems have a large number of elements, and therefore the reliability of such systems depends not only on the reliability of the individual elements, but also on the nature of the connections between them. Carrying out the reliability analysis of transport systems is possible with the help of their structural functional circuits of reliability and unlike physical circuits that reproduce physical connections between elements, logical reliability circuits are built to show what combinations of failures of individual elements of the system lead to failure of a circuit or system in general. Thus, the construction of logical reliability schemes is based on the analysis of the consequences of the causes of failures of individual elements, which can later be used in the development of theoretical bases for improving the reliability of the functioning of road transport systems.

Abstract:

Data from the California Tree Failure Report Program (CTFRP) were analyzed to develop a profile of the structural failure characteristics for coast live oak (Quercus agrifolia). The most common pattern of structural failure for coast live oak reported in the CTFRP is a root or low trunk failure of a naturally occurring tree growing in a residential site. Decay, site grade changes, and low wind speeds are significantly more frequently associated with coast live oak failures than with other hardwoods, conifers, or eucalyptus. Decay of roots and lower trunk was a major contributing factor to failure of coast live oak (83%). Saturated soil conditions associated with root failure were also more frequent for coast live oak than for other species groups. Careful attention to controlling excess soil moisture, avoiding or correcting grade change and compaction, and monitoring decay are essential to maintain the health of coast live oak.

Abstract:

Nowadays, U-shaped thin-walled concrete girders have been widely applied in the urban construction of rail viaducts in China as well as worldwide. However, the mixed torsional behaviors of these structures are not well understood. In this paper, the mixed torsional behaviors of the U-shaped thin-walled RC girders are theoretically analyzed, and a method predicting failure modes and ultimate torques is proposed. Nonlinear FE models based on ABAQUS to simulate the mixed torsional behaviors are built and calibrated with the test results. Parametric studies considering three crucial parameters (boundary condition, span length-section height ratio, and ratio of longitudinal bars to stirrups) are conducted based on both the above suggested calculating method and the FE modeling. The calculated and the simulated results agree well with each other and with the test results. It is found that the failure modes of the U-shaped thin-walled RC girders under torsion are influenced by all the three parameters. Three kinds of failure modes are observed: flexural failures dominated by warping moment, shear failures caused by warping torque and circulatory torque, and flexural-shear failures in the cases where flexural failure and shear failure appear almost at the same time.

The objective: аnalysis of complications after endoprosthetic reconstruction in children and adolescents according to the Henderson classification of failure of limb salvage surgery modified by the International Society of Limb Salvage committee (ISOLS).Materials and methods.This study evaluates complications rates and mode of failures after endoprosthetic reconstruction for the tumor around the knee in 97 patients treated from 2012 to 2018 in D. Rogachev National Medical Research Center of Pediatric Hematology, Oncology, Immunology.Results. Overall 19,6 % of failures were identified. The most common postoperative complications were structural failu res, infection and soft-tissue failure (6,19; 5,15 and 3,1 % respectively). None of the developed failures affected the timing of treatment protocol.Conclusion. Literature review and the study results demonstrate that higher risk of failure in the paediatric group of patients is attributed to deficiency of adjacent soft-tissue and bone, skeletal immaturity, using of expandable endoprostheses and increased patient activity at this age. Multicenter studies are needed to optimize prevention and management of failures after endoprosthetic reconstruction.

Abstract:

Production lines are usually subjected to emergent machine failures. Such emergent failures disrupt pre-established maintenance schedules, which challenge maintenance engineers to react to those failures in real time. This research proposes an optimization procedure for optimizing scheduling repairs of emergent failures. Three optimization models are developed. Model I schedules failures in newly idle repair shops with the objective of maximizing the number of scheduled repairs. Model II maximizes the number of assigned repairs to untapped ranges. Model III maximizes both the number of assigned failure repairs and satisfaction on regular and emergency repairs by resequencing regular and emergent failures in the shop that contains the largest free margin. A real case study is provided to illustrate the proposed optimization procedure. Results reveal that the proposed models efficiently scheduled and sequenced emergent failures in the idle maintenance shops, the untapped ranges between repairs of regular failures, and in the maintenance shop with the largest free margin. In conclusions, the proposed models can greatly support maintenance engineers in planning repairs under unexpected failures.

Abstract:

A probability-based approach, combining deterministic and probabilistic methods, was developed for analyzing building and component failures, which are especially crucial for complex structures like nuclear power plants. This method links finite element and probabilistic software to assess structural integrity under static and dynamic loads. This study uses NEPTUNE software, which is validated, for a deterministic transient analysis and ProFES software for probabilistic models. In a case study, deterministic analyses with varied random variables were transferred to ProFES for probabilistic analyses of piping failure and wall damage. A Monte Carlo Simulation, First-Order Reliability Method, and combined methods were employed for probabilistic analyses under severe transient loading, focusing on a postulated accident at the Ignalina Nuclear Power Plant. The study considered uncertainties in material properties, component geometry, and loads. The results showed the Monte Carlo Simulation method to be conservative for high failure probabilities but less so for low probabilities. The Response Surface/Monte Carlo Simulation method explored the impact load–failure probability relationship. Given the uncertainties in material properties and loads in complex structures, a deterministic analysis alone is insufficient. Probabilistic analysis is imperative for extreme loading events and credible structural safety evaluations.

Abstract:

There is little in the way of test results for structural tees used in tension. This is especially true when it comes to results for block shear failures. By varying only the depth of the web, a limited experimental program was designed to produce failures ranging from net section to block shear for tees connected by bolts through their flanges. As the depth increased, block shear failures did result, but not along the paths anticipated. This alternate block shear path is the focus of this paper.

Abstract:

Abstract: Road widening projects are undertaken to accommodate increased traffic volume and improve transportation infrastructure. However, in some cases, structural failures can occur in the widened road sections, leading to safety hazards and increased maintenance costs. This study aims to investigate the causes of structural failure in road sections after widening and propose remedial measures to mitigate the issues. The research methodology involved field inspections, data collection, and analysis of failed road sections. Various factors contributing to structural failures were identified, including inadequate design considerations, improper construction techniques, and insufficient soil stabilization measures. The study also examined the effects of increased traffic loads and environmental factors on road performance. Based on the analysis, several remedial measures were proposed to address the structural failures. These measures include retrofitting the road sections with additional reinforcements, improving drainage systems to prevent water accumulation, and implementing proper soil stabilization techniques. Additionally, recommendations for enhanced quality control during construction, such as strict adherence to design specifications and regular monitoring, were suggested. Furthermore, the study emphasized the importance of considering longterm maintenance requirements during the road widening process. Establishing a comprehensive maintenance plan that includes periodic inspections, timely repairs, and proactive maintenance strategies can significantly prolong the service life of the widened road sections

Abstract:

In the beginning, man lived in shelters made from the abundant natural resources at hand. They learned where to construct their tents to avoid the effects of natural disasters. In the event of a breakdown, they may be fixed using only naturally occurring, low-cost components. Yet, as the world's population rises and new construction techniques emerge, it becomes crucial to understand why certain buildings have structural problems and what can be done to fix them. Materials used in engineering construction may deteriorate over time for a number of reasons, leading to structural failures. This study examines the causes of structural failures such as bad planning, low-quality materials, sloppy construction, bad luck, and extreme weather. Also covered are the different approaches to carrying out the necessary repairs, commonly known as corrective actions.

Abstract:

This article focuses on importance of visual inspection to observe conditions that can lead to structural and non-structural failures in civil construction. The subject article is based on structural failure reports information, condition assessment in generalized manner and practices which are being accepted in normal practices. Visual inspection procedures may help to identify the structural deficiencies in particular structural elements prior to becoming critical to challenge overall stability of integrated structure. Only generalized dangers can be revealed in visual inspections of the deterioration of structures. Experienced structural engineer is required for complete analysis of major structural defects.
