Abstract
In order to simplify the modeling job for analysis of reinforced concrete structures, longitudinal rebar can be simulated with equivalent box section instead of being embedded in concrete section. Separate model and monolithic model are researched by using numerical method. Numerical results show that these two models can present almost the same solutions in linear analysis, but the differences in nonlinear analysis should not be neglected. In separate model, concrete may be damaged more serious than monolithic model, but both the load bearing capacity and ductility of separate model are overestimated because the contribution of rebar has been amplified improperly. So the reinforcement ratio should be reduced properly in nonlinear analysis while using separate reinforcement model
