Frame analysis of reinforced concrete shear walls with openings

Abstract

There are several types of analysis methods available for analysing shear walls of the building structures. Frame analyses is one of the methods, and were used in this study to determine the ultimate strength of reinforced concrete coupled shear wall structures and its structural behaviour under lateral loading. Multiframe Version 5.16 software which based on linear (first-order elastic) analysis method were used to analyse the shear wall models adopted from previous research. Results show that linear elastic of frame analysis method was overestimating the ultimate strength of shear wall models and not reliable enough for this analysis compared to analytical Continuous Connection Method (CCM) and Non-Linear Finite Element Analysis (NLFEA) method. The difference was about four times higher than the experimental results being conducted by the previous researcher. However the structural behaviour of walls and its coupling beam at ultimate condition was still pose similar behaviour to the observation made on the experimental test and Non-Linear Finite Element Analysis (NLFEA).
