Abstract

Due to architectural reasons and constraints on the plan structure, Openings such as doors, windows and installations ducts have been created on the Concrete Shear Wall. It causes some changes in behavior, stiffness, Load Capacity and failure mechanism of specimens. In this paper, ABAQUS software is used for finite element modeling and investigating the parameters. In order to verify the results of this software, a scaled six stories wall with two bands of Openings are modeled in ABAQUS software and compared with experimental results. After verification, parameters of Opening area and position, bands of Opening coupling, beam dimensions and diagonal reinforcement are investigated by non-linear finite element method using concrete Damage Plasticity model (CDPM) under the monotonic loading. Results further confirm that if dimensions of Opening do not change the failure mechanism of the wall, the Opening position will be more effective than the Opening area. In specimens with two bands of Opening, making a ratio of lateral pier length to middle pier length more than 50%, increases effective compressive area and coefficient correlation and thus the sample has reached its maximum Load Capacity. Setting the diagonal reinforcement both on coupling beam and in other compressive parts of the wall (base wall), decreases the crack propagation and augments the compressive area of the wall. It also leads to increase the Load Capacity of specimens by 19. 6 %. The comparison of results also showed that a specimen with coupling beam height to height floor ratio of 0. 52, the use of diagonal reinforcement on the coupling beam and putting up them in the base wall can be a suggestion for appropriate design of Concrete Shear Wall with an Opening.
