Some Key Issues of Elasto-plastic Analysis for RC Frame Structure Retrofitted by FRP

摘要

Based on summary and analysis of research results for RC frame structure retrofitted by FRP, the significance and necessity of elasto-plastic time history analysis was pointed out. Some key issues of elasto-plastic analysis using ABAQUS for RC frame structure retrofitted by FRP were discussed in the following aspects: the selection of modeling method and element type, restoring force model, and the definitions of steps and load, etc. Then several feasible suggestions were put forward.
