NONLINEAR ANALYSIS OF SHEAR CRITICAL RC MEMBERS USING CURRENT FE SOFTWARE

Abstract eng:
The shear behaviour of concrete has been widely studied in the field of structural engineering, yet it is still considered an unresolved issue. In one hand, the design codes provide diverse methods to estimate the shear capacity of concrete with different results. On the other hand, analytical models to assess the performance of shear critical concrete members have been proposed by several authors. These models have been developed using different assumptions. Some of the theories have been implemented in finite element software packages that are used by engineers in academia and in the industry. This study presents an investigation of the state-of-the-art software packages for the analysis of shear critical concrete elements. The theory implemented on each software is detailed and analysed. To evaluate the capacities of the packages, some benchmark tests have been used for both monotonic and cyclic loading cases. The presented results show the capabilities and limitations of the programs from the experience obtained during the duration of this work. Just as well, the results among the programs are compared among themselves as well as the results from other authors.
