Abstract:

A deep beam is a beam with a small ratio of its shear span to its effective depth. Deep beams at failure under shear mechanism behave as brittle in contrast to the normal beams which become ductile under the flexural mechanism. The shear failure of deeps beams can be prevented by providing a sufficient amount of web shear reinforcements. Providing horizontal web reinforcement to the RC deep beams is a way to increase their capacity to shear. Testing of the studied deep beams was performed by Finite Element Method (FEM) modeling with the aid of ANSYS software. To obtain valid parameters for modeling RC deep beams in FEM modeling, calibrating test have to be done through verification and validation processes. The study results of all studied RC deep beams show that by closing up the spacing between the horizontal web reinforcement results in increment in the ultimate load, while the ultimate deflection and the curvature ductility were found to be decreasing. For RC deep beams, the placing configuration of horizontal web reinforcement at 0.5h-0.7h was found to be efficient for gaining higher values of ultimate deflection and curvature ductility compared to the placing configuration at 0.3h-0.5h with similar values of ultimate load. It was also found that all the specimens’ crack patterns at the first crack state were caused by flexural-tension while at the ultimate state, they were caused by the shear mechanism.

Abstract:

Background: When a beam is loaded on two opposite faces and the beam’s depth is increased such that either the span-to-depth ratio is smaller than four or the shear-span-to-depth ratio is less than two, it will behave like a deep beam. Strain distribution in deep beams is different from that of ordinary beams because it is nonlinear along with the beam depth. If the beam is cast monolithically with a slab in the slab–beam system, it is considered a T-deep beam. The behavior of the resulting member is more complicated. Objective: The effect of flange width on the behavior of high-strength self-consolidated reinforced concrete T-deep beams was investigated. Methods: Experimental and numerical studies were conducted. Two shear span-to-depth ratios (1.25 and 0.85) were adopted for two groups. Each group consisted of four specimens: one rectangular beam that served as a reference beam and three flanged beams with flange widths of 440, 660 and 880 mm. All specimens had an overall depth of 450 mm, a width of 160 mm and a total length of 1600 mm. The tests were performed under a two-point load with a clear span of 1400 mm. A nonlinear analysis was also performed using ANSYS software. Results: Throughout the study, the performance of the T-deep beams has been investigated in terms of cracking loads, failure loads, modes of failure, loading history, rate of widening of cracks and ductility index. Results revealed that such parameters have a different ranges of effect on the response of T-deep beams. Calibration of the ANSYS model has been done by comparing results of load-deflection curves, cracking and failure loads with that obtained experimentally. Conclusion: The study’s results indicated that increasing the flange width yielded an 88% improvement in the failure load and an approximately 68% improvement in the cracking load. This positive effect of flange width on the failure load was more pronounced in beams with higher shear span to- depth ratios and flange widths of 660 mm. In addition, the beam’s ductility was improved, especially in cases corresponding to a higher shear span-to-depth ratio. The finite element simulation showed good validation in terms of the load-deflection curve with a maximum failure load difference of 9%. In addition, the influence of longitudinal steel reinforcement on the behavior of such members was studied. Some parameters that reflect the effect of changing the flange width on the behavior of deep beams were also presented. Increasing the flange width is more effective when using normal strength concrete than when using high-strength concrete in terms of cracking load, beam stiffness, and failure load.

The paper presents the results of experimental study carried out by authors on the deep beams with cantilever which was loaded throughout the depth. The main deep beam was directly simply supported on the one side. On the other side the deep beam was suspended in another deep member situated at right angles. All deep beams created a spatial arrangement. The tested deep beams were reinforced orthogonally. Crack patterns and the mode of the failure as well shear concrete were analyzed for their influence on load carrying capacity of the deep beams.

Abstract:

Based on strut-and-tie model (STM) in deep beams, steel truss reinforced concrete (STRC) deep beam was developed. Experimental investigations of mechanical performances of STRC deep beams were carried out, and results show that STRC deep beam is of high ultimate bearing capacity, large rigidity and good ductility; Strut-and-tie force transference model is formed in STRC deep beams, and loads can be transferred in the shortest and direct way. Then Steel reinforced concrete (SRC) strut-and-tie model (SSTM) for determining the shear strength of STRC deep beams is proposed. The contribution of SRC diagonal strut, longitudinal reinforcements, stirrups and web reinforcements to the shear strength of STRC deep beams are determined with consideration of softened effects of concrete, and for safe consideration, superposition theory is employed for SRC struts. Computer programs are developed to calculate the shear strength of STRC deep beams and verified by experimental results.

Abstract:

The test results of six reinforced concrete moderate deep beams with embedded PVC pipes are reported. The tests studied the effect of installation of PVC pipe on behavior of reinforced concrete moderate deep beams. The test parameters were the diameters and locations of the pipes. The dimensions of beams were 1000 mm length, 150 mm width and 300mm depth. One beam was constructed without pipe as control and the remaining five had embedded pipes. Four pipe diameters were used: 25.4, 50.8, 76.2, and 101.6 mm and these pipes were inserted longitudinally either at the center of the beams or near the tension reinforcement. The beams were simply supported and tested under central concentrated load up to failure. The test results indicated that, the pipe diameter less than 1/3 of the beam width had limited effect on the capacity and rigidity of beam. For larger pipes, the ultimate strength of beams decreased between 16.7% and 33.3% and the beams stiffness decreased between 103% and 297%.

Abstract:

The present study explains about the behavior of Deep beams in both experimental and analytical aspect. Considering the maximum moment from the analytical analysis, the Deep beams are designed according to the IS-456[2000] codal provisions. The failure of deep beams is mainly due to shear, which is considered as a catastrophic failure and many studies are being done on their behavior, some studies concluded that strut-tie- method(STM) is most relevant, but the IS-456(2000) code has no provisions regarding the STM. So, in the present study, the reinforcement area obtained in conventional design of deep beams as per IS provisions were arranged in the form of truss. Thus, comparing the behavior of conventional reinforced Deep beams with truss configured Deep beams, and comparing experimental results with analytical results of Deep Beams. The results concluded that the truss reinforced Deep beams shown good results compared to Conventional Deep Beams and IS-456 code need to be updated for the deep beam design in various approaches.

Abstract:

Results of test on seven simply supported self-compacting reinforced concrete deep beams, including six of these beams containing circular openings in center of load path are reported in this paper. The objective of the tests was determined the influence of, changing shear span to effective depth ratio a/d, the existence of circular openings in shear span and using inclined strips of carbon fiber polymer (CFRP) on behavior of deep beams. The general trend in crack pattern, the load-deflection response, and the mode of failure of reinforced SCC deep beams were also investigated. All specimens had the same geometry, details of the flexure and shear reinforcement in both vertical and horizontal directions and they were tested under symmetrical two-point loads up to failure. The experimental results revealed that the web openings within shear spans caused an important reduction in the deep beam capacity by 50% when compared with the corresponding solid beam. The increase a/d ratio from 0.8 to 1.2 decreases the ultimate load by 21.7% and 22.5 % for the reference unstrengthened beam and strengthened beam, respectively, also it was found that the externally inclined CFRP strips in deep beams increased the ultimate strength up to 39.5%, and enhanced the stiffness of deep beams with openings.

Abstract:

This investigation presents an experimental and analytical study on the behavior of reinforced concrete deep beams before and after repair. The original beams were first loaded under two points load up to failure, then, repaired by epoxy resin and tested again. Three of the test beams contains shear reinforcement and the other two beams have no shear reinforcement. The main variable in these beams was the percentage of longitudinal steel reinforcement (0, 0.707, 1.061, and 1.414%). The main objective of this research is to investigate the possibility of restoring the full load carrying capacity of the reinforced concrete deep beam with and without shear reinforcement by using epoxy resin as the material of repair. All beams were tested with shear span-depth ratio 2.2. An analytical study was made to show the behavior of a sample of test beam at higher stages of loadings before and after repair. The test results showed that the epoxy resin used for repairing was very efficient in restoring full capacity of failed beams. Moreover, epoxy resin increased the strength capacity of the original beams by about 14% to 40%. On the other hand, the increase in the longitudinal reinforcement increased significantly the ultimate capacity of deep beams before and after repair.

Abstract:

Twenty five model beams were progressively loaded to failure in order to investigate the influence of the following variables on the behaviour of reinforced concrete deep beams : i) Concrete compressive strength ii) Reinforcement iii) Geometry. The model beams were all of 1500mm span, with a depth of 750mm. This span to depth ratio of 2 corresponds to the upper limit, to which the recommendations for deep beam design applies, as provided by many current codes of practice. Methods currently in use for the design of reinforced concrete deep beams were reviewed and compared. The experimental results were compared with the predictions of these design methods. This comparison revealed a large lack of agreement in the predictions of the cracking and ultimate strengths of deep beams.

Abstract:

This thesis presents the results of an experimental, numerical and analytical study to develop a design method to calculate shear resistance of flanged ferrocement beams with vertical mesh reinforcements in the web. Two groups of full-scale testing were conducted comprising of three I beams and four U beams. The I beams had the same geometry and reinforcement arrangements, but differed in the matrix strength or shear span to depth ratio. The U beams differed in web and flange thickness, reinforcement arrangements, matrix strength and shear span to depth ratio. The experimental data were used for validation of finite element models which had been developed using the ABAQUS software. The validated models were subsequently employed to conduct a comprehensive parametric study to investigate the effects of a number of design parameters, including the effect of matrix strength, shear span to depth ratio, cross sectional area, length of clear span, volume fraction of meshes and amount of rebar. The main conclusion from the experiments and parametric studies were: shear failure may occur only when the shear span to depth ratio is smaller than 1.5; the shear strength may increase by increasing the matrix strength, volume fraction of meshes, cross sectional area and amount of rebar. The main type of shear failure for I beams was diagonal splitting while for U beams it was shear flexural. Based on the results from the experimental and numerical studies, a shear design guide for ferrocement beams was developed. A set of empirical equations for the two different failure types and an improved strut-and-tie were proposed. By comparison with the procedures currently in practice, it is demonstrated that the methodology proposed in this thesis is likely to give much better predictions for shear capacity of flanged ferrocement beams.

Abstract:

RC deep beams are key safety critical structural systems carrying heavy loads over short span, such as transfer girders in tall buildings and bridges. Current design provisions in codes of practice fail to predict accurately and reliably the shear capacity of RC deep beams and in some cases they are unsafe. This work aims to develop a better understanding of the behaviour of RC deep beams and governing parameters, and to improve existing design methods to more accurately predict the shear capacity of such members. An extensive experimental programme examining 24 RC deep beams is carried out. The investigated parameters include concrete strength, shear span to depth ratio, shear reinforcement and member depth. To develop a better insight on the distribution and magnitude of developed stresses in the shear span, finite element analysis is also performed. The microplane model M4 is implemented as a VUMAT code in ABAQUS to represent the behaviour of concrete in a more reliable manner and validated against experimental tests on RC deep beams. This model is utilised in a parametric study to further investigate the effect of concrete strength, shear span to depth ratio and shear reinforcement. The experimental and numerical results show that concrete strength and shear span to depth ratio are the two most important parameters in controlling the behaviour of RC deep beams, and that shear strength is size dependent. The analysis also shows that minimum amount of shear reinforcement can increase the shear capacity of RC deep beams by around 20% but more shear reinforcement does not provide significant additional capacity. A lateral tensile strain based effectiveness factor is proposed to estimate the strength of the inclined strut to be used in strut-and-tie model. Additionally, node factors to estimate the developed strength in different type of nodes are proposed. The proposed model is evaluated against a large experimental database and the results show that it yields more accurate and reliable results than any of the existing models. The model is characterized by the lowest standard deviations of 0.26 for both RC deep beams with and without shear reinforcement and accounts more accurately for all influencing parameters.

Abstract:

The work described in this thesis is concerned with the behaviour, analysis and design of reinforced concrete beams. A brief historical review of the methods of analysis on deep beams is given. The current major codes of practice and design manuals associated with reinforced concrete deep beams are reviewed. This study has been useful in identifying the limitations of the current design documents on the subject of deep beams. Because of the acute shortage of information regarding buckling, web-opening and combined loading, three test programmes are performed to provide experimental evidence on these topics. Their behaviour is examined in terms crack developments, crack patterns, modes of failure, in-plane and lateral displacements, ultimate loads, strains and stresses. The ultimate buckling strength of the slender deep beams without web-openings are analysed using the methods described in the CIRIA Guide (1977). Adopting the same methods in the guide, an attempt has been made to analyse the buckling strength of deep beams with web-openings. Based on the structural idealization of Kong et al (1973), a modified approach is proposed for the ultimate shear strength of deep beams with web-openings. In addition, the CIRIA ultimate shear interaction equation for deep beams under combined top and bottom loadings is studied and an equation is proposed for the uniformly distributed loading cases. Finally, based upon these findings, some design recommendations are given.

Abstract:

Reinforced concrete deep beams have useful applications in construction. However, their design is not yet covered by the British Standard BS 8110: 1985 which explicitly states that "for the design of deep beams, reference should be made to specialist literature". A selection of literature on deep beams is considered. First, the major works that have led to design recommendations are reviewed. Then, the current major codes and manuals covering deep beams, namely the CIRIA Guide, the European CEB-FIP model code, the American ACI(318-83) (revised 1986) code and the Canadian CAN3-A22.3-MB4 code are outlined; worked examples are given in order to illustrate their practical applications and compare their different approaches to deep beam design. The purpose of this literature review was to define the deep beam problem and identify the major questions still remaining unanswered together with the limitations of the present design documents on the subject. The nature of diagonal cracking in slender deep beams has recently raised a question as to the application of the shear-strength equation in cl.3.4.2 of the CIRIA Deep Beam Guide. The effectiveness of web reinforcement on serviceability and strength of deep beams in general is also an area where strong disagreement exists. A testing programme, consisting of 15 beams of height/thickness ratios ranging from 20 to 50 and grouped in 3 different series, was performed to provide information on these two areas. The main variables were the height/thickness ratio and the quantity and arrangement of web steel. The beams were tested under concentrically applied two point-loads. Based on the test results and observations, modifications are given for the CIRIA equation and other formulae derived from stocky deep beam tests to be used in slender ones for analysis and design purposes. A new formula is also proposed for the prediction of the ultimate shear capacity. The stability of deep beams is another area which has received less attention in the past by researchers and designers who often avoided the problem by opting for stocky sections. To quote from the CIRIA Guide "as a possible criterion of failure, buckling can not be disregarded". However, information on such topic is very scarce in the literature. Currently, the only documents that provide design guidelines for buckling are the CIRIA Guide and the Portland Cement Association Design Aid, both of which are based on theoretical studies and engineering judgement. An experimental testing programme, consisting of 7 large scale beam-panels with height/thickness ratios in the range of 20 to 70 and a constant span/depth ratio of 1.0, provided buckling data against which the reliability of the two design documents was assessed. These tests confirmed that both documents offer a safe buckling design with the CIRIA Guide being too conservative. Although deep beams are frequently continuous over several spans, very little published data exist for such beams. For this purpose, 12 two-span continuous concrete deep beams with span/depth ratios less than 1.0 and having different quantities and arrangements of web reinforcement were tested under two point-loads. The specimens were heavily instrumented to obtain as much information as possible about the behaviour of the beams at each stage of loading. Applied loads and reactions were among the measurements made and enabled the actual bending moment distribution to be determined and compared to that of corresponding continuous shallow beams. Based on the test results and observations and in the light of other published work, recommendations are given for the bearing, shear and flexural design of continuous deep beams.

Abstract:

As part of a research program at McGill University, involving the testing of eight full-scale deep beams, this research studies the response of four full-scale deep beams that were designed in accordance with the strut-and-tie model provisions of the CSA Standard A23.3 (2004). All of the deep beams had a centre-to-centre spacing of 2000 mm between the two supports, 1000 mm in height, and 350 mm in thickness. They were simply supported with an application of a single point load at midspan. The total length of the four beams varies depending on the type of anchorage being used. The four anchorage details that were considered in this study include a straight development length, a standard 90 degree hook, friction-welded 1.5 in. (38 mm) diameter circular headed bars and friction-welded 2 in. (50 mm) diameter headed bars. The dimensions of the loading pad and the bearing pads were 200 mm (and 300 mm) and 100 mm, respectively. All beams were reinforced with two layers of five 15M bars forming the tension tie reinforcement. El-Jorf (2006) carried out the testing and analysis of the other four full-scale deep beams in this overall research program.
This research project demonstrated that providing friction-welded circular headed bars capable of developing the full yield strength at the head results in shorter beams and improved response compared to straight bar embedment details. Providing a lead-in length as well as friction-welded circular headed bars, with reduced head size, provides improved ductility compared to the straight bar embedment and compared to the hooked anchorage. This research also shows that benefits of confinement pressures at the supports can increase the bar stress although the provided development length is below code requirements.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
As principais recomendações para o dimensionamento de vigas-parede, como o ACI 318-95, o CEB-FIP, a Norma Canadense CAN-A23.3-M84 e o Guia 2 da CIRIA, apresentam métodos de cálculo que não cobrem satisfatoriamente o projeto de tais vigas. Outras normas, ainda, não trazem nenhuma indicação especial de dimensionamento. A própria Norma Brasileira, a NBR 6118, por exemplo, declara apenas que vigas desse tipo devem ser calculadas como chapas no regime elástico. O Código Britânico corrente BS 8110 explicitamente comenta que “para o projeto de vigas-parede, referência deve ser feita à literatura especializada”. Por razões como as citadas acima, a obtenção de um método racional, baseado em um claro mecanismo de ruptura e que leve em conta os principais parâmetros que influenciam a resistência última das vigas-parede tem sido o objetivo de vários pesquisadores de todo o mundo nas duas últimas décadas. Neste trabalho são apresentados, comentados e analisados vários métodos de dimensionamento de vigas-parede biapoiadas de concreto armado. Os métodos de cálculo são aplicados ao total de trinta e sete vigas ensaiadas no Laboratório de Estruturas e Materiais (L.E.M) da PUC-Rio, desde 1979, e a algumas vigas descritas na literatura, visando a obtenção de um método que gere resultados de carga última os mais próximos possíveis dos obtidos experimentalmente, e tendo como objetivo futuro a obtenção de recomendações que possam ser propostas para a Norma Brasileira.Os ensaios das trinta e sete vigas, no total, referenciadas acima, fazem parte de pesquisas teórico-experimentais realizadas na PUC-Rio por Guimarães (1980), Vasconcelos (1982) e Velasco (1984), sob a orientação do Prof. K. Ghavami. Várias conclusões foram obtidas em cada uma dessas dissertações de mestrado, separadamente, mas nenhum estudo havia sido feito no sentido de comparar os resultados encontrados. O presente trabalho também tem como objetivo obter informações comparativas relacionadas às 37 vigas citadas, com o respaldo da literatura atualizada.
The major codes that contain recommendations and discussions concerning the design of deep beams, including the ACI Building Code 318-95, the Canadian Code CAN-A23.3- M84, the CEB-FIP Model Code and the CIRIA Guide 2, present design methods that do not cover adequately the dimensioning of this type of beams. Nevertheless, some other codes don’t give any special recommendation. The Brazilian Code (NBR 6118), for instance, just explains that this type of beams should be calculated as a plate in elastic range. Another example is the current British Code BS 8110, which explicitly states that “for design of deep beams, reference should be made to specialist literature”. Because of reasons as those mentioned above, obtaining a rational method not only based on a clear mechanism of failure but taking into account the main parameters that have influence on the ultimate strength of deep beams, has been the purpose of several researchers in the whole world in the last two decades. In this work, some methods for the design of simply supported reinforced concrete deep beams are presented, examined and commented upon. These methods are applied to a total of 37 beams tested in the Laboratory of Structures and Materials (L.E.M) of PUC-Rio, since 1979, and to some beams reported in the literature, in order to yield a method which can predict results of ultimate load closer to those ones obtained experimentally. The future aim is to achieve recommendations that could be proposed to the Brazilian Code. The tests of the 37 beams just referred are included in theoretical-experimental research done by Guimarães (1980), Vasconcelos (1982) and Velasco (1984), which took place in PUC-Rio, orientated by Professor Khosrow Ghavami. Several concluding remarks were obtained in each Master Thesis, apart from one another, but there wasn’t any work that compared these results. The present work is also intended to provide some comparative information regarding the 37 deep beams mentioned above, with the support given by the current literature.
