Investigation of the behavior of reinforced concrete-coupled shear wall with opening using IDA analysis

Abstract

In a tunnel formwork system, concrete pour of the walls and ceilings is usually combined simultaneously and is done in one step. This causes the structure to be homogenized and also minimizes the number of cold connections in the structure. This system includes static formworks; thus, during the implementation of the structure, these formworks are seamlessly moved from place to place by lifters and cranes. This system combines quality, accuracy, and pace. An incremental dynamic analysis is a parametric analysis based on nonlinear dynamic analysis. This analysis method has been approved by the Federal Emergency Management Agency (FEMA) in the last decade and has been considered in the FEMA 350 and FEMA 351 standards for determining the overall disruption capacity of the structure. In this study, two, one-story buildings, one of which including openings and the other not including one, is analyzed by the ABAQUS software. The results indicate that the building without an opening demonstrates a better behavior than the one including openings. In this study, the effect of existence of openings on base shear as well as ductility and resistance factor, which are effective factors on the response modifier factor, is considered.
