Dynamic Analysis of a Reinforced Concrete Shear Wall with Strain Rate Effect

摘要

A simplified analysis method for a reinforced concrete shear wall structure considering strain rate effects is presented. The model uses a strut-and-tie simplified model with concrete strut and steel rebar elements comprising a three-element Maxwell model. The results of dynamic response analysis show very good agreement with the test results of the ISP (International Standard Problem sponsored by OECD/NEA/CSNI) shear wall in the nonlinear response region including at the maximum strength point. Some differences are observed in the elastic range and failure mode. The effective strain rate for increasing strength is less than one half of the maximum strain rate and 70 percent of the root mean value in this study.
