Reinforced Concrete Shear Wall with properties such as high stiffness, proper operation in earthquake, Ductility and high carrying capaity in seismic zomed as a suitable and reliable structural system for dealing with earthquake side forces in concrete buildings in a wide area has been used on the other hand, due the limited archi tectural existence, the opening in the shear wall is inevitable and a solid shear wall is used in reinforced concrete structural. Creating an opening in the shear wall of reinforced concrete, expecially in the load transfer path, can have a great influence on the behavior of the well. In this article, using ABAQUS limited element software, the effect of creating an opening with variaud shopes and positions on the concret shear wall strueture has been investigated.
In this Article, the shear wall is 750 to 750 mm in size and opening with 10% area of the concrete shear wall are modeled to a ceircular and triamgular shaft and a rectangular in thr center of the shear wall. Acording to the results of this research, it can be seen that, due to the comparison of different forms the shape has the best performance which has less sharp corners, resulting in a better performance rhythm also concrete damage is more pronounced in areas with shao corners.
