Abstract

This paper presented a nonlinear finite element analysis of lateral loading RC shear walls with regular openings using the 3D-NLFEA program. The RC shear walls model was generated from the available test results in the literature. To model the concrete under a complex stress state, a multi-surface plasticity model which combines compression failure surface with tension cut-off failure surface was used. The model was intended to look at the load-displacement relationship and the crack pattern between the model and the numerical model. In addition to the numerical model verification, parametric studies were carried out to investigate the use of high-strength steel (HSS) of the two different grades (grades 100 and 120) to replace all the normal-strength steel (NSS) or only some of it. The parametric studies found that the shear wall with the NSS bar demonstrated higher stiffness and achieved higher lateral load with the lowest extent of damage (compared to the RC shear wall with the HSS bar). On the other hand, using the HSS bar resulted in lower stiffness, lower lateral load, and higher damage region, which was expected as more strain is required to yield the HSS bar.

Abstract

This paper describes an attempt to predict the flexural response of a reinforced concrete (RC) beam using nonlinearfinite element analysis. To facilitate direct comparison, the beam was tested experimentally under four-point bending with theload increased monotonically. The load-deflection response, crack pattern and failure mode were observed in the experiment.Analysis incorporating the application of ATENA 3D was performed using the fracture-plastic model which is based on theclassical orthotropic smeared crack formulation and crack band model. The applicability of this model was demonstratedthrough detailed simulation of RC beam with identical geometry, reinforcement arrangement, and material properties. Fromthis study, it is found that the overall predicted responses are in very good agreement to those obtained from the experiment.It is also found that the feature in ATENA enables the presentation of reasonably maximum principal strains of concrete andrebar elements which can, therefore, be associated with the predicted crack bands.

Abstract

This paper explores the accuracy of nonlinear finite element procedures implemented in ATENA in predicting the load-deformation response of reinforced concrete coupling beams with headed bars under reversed cyclic loading. In this study, the coupling beam (incorporating headed bars) tested by Seo and co-workers in 2017 is analysed and its response at different lateral drifts is discussed. Parametric analyses, studying the influence of reinforcement layouts, are also presented. It is shown that the hysteresis loops of the coupling beam could be predicted accurately, along with the crack patterns at different stages of loading and failure mode. It is also shown that the omittance of headed bars resulted in more pronounced bond-slip effects and a more severe pinched response in the post-peak region, highlighting the importance of providing adequate headed reinforcement. A similar trend was observed in the coupling beam with the omittance of U-bars and horizontal transverse reinforcements, whereas the reduction of stirrups was found to increase the prominence of shear failure.
