Nonlinear analysis of reinforced concrete beam : a case study / Zulkornain Yusoff

A number of material-related factors can cause stiffness of structure to change during the course of analysis. Nonlinear stress-strain relationship of plastic will cause a structure stiffness to change at different load levels. In this study, the nonlinear finite element analysis of a reinforced concrete beam using ANSYS (Swanson Analysis System), a finite element analysis system is presented ANSYS element was utilised to model the beam in three dimension (3D) were adopted in the analysis, Two case of support conditions were adopted in the analysis, i.e. firstly considering no anchorages and secondly with proper anchorage at the end joints. Crack propagation was also studied on the beam
