A Study on Evaluation Method of Structural Performance for Seismic Walls with Mortar by Finite Element Analysis

Abstract

When constructing additional reinforced concrete seismic walls to existing buildings, mortar is sometimes required instead of concrete, which does not impair the habitability and the usability of the building during construction. However, compared to concrete, mortar has greater drying shrinkage and different shear stress transfer characteristic at the crack interface, so the performance of reinforced mortar seismic walls differs from that of using concrete. In this study, a static loading test and nonlinear finite element analyses were conducted in the three-dimensional stress field simulating the test to establish the method for evaluating the structural performance of reinforced mortar walls. As a result, the hysteresis behavior of the reinforced mortar seismic wall measured in the experiment could be properly evaluated by the analyses.
