Examine the Possibility of Increasing the Size of Openings According to Seismic Behavior of Masonry Structures Isolated with Sliding Layer Compared with the Fixed Structures Under Naqan Earthquake

Abstract

Masonry buildings have a large share in the context of large and small towns, For example, in the city of Bam more than 90 percent of the buildings with brick and masonry structures, which are about 40% of the amount of masonry structures. According to reports, all masonry buildings are damaged in the earthquake of 20 to 100 percent. Research shows that the bulk of the damage to buildings caused by non-compliance with the provisions of the Building Regulations 2800, including the opening of the wall, the opening in the wall, resulting space restrictions, the wall of the building and etc. In this paper, a masonry structures under earthquake made great naqan modeling the structures in abaqus software in the form of macro, and the first to be connected and then a layer of sand sliding sought to separate the topside of the use and analyzed them. After this, the effect on the seismic behavior of the proposed system and create havoc in the corners of the openings are possible. Find answers to the two-state system; it is found that the proposed isolation system, while considerably reducing damage, the size of the openings can be considered more of a standard.
