Abstract

Compared to regular columns, short columns absorb more earthquake force due to their greater stiffness. For this reason, short columns are seriously damaged during an earthquake and sometimes cause the destruction of the entire structure. When short columns are displaced as much as long columns, shear and joint failure occurs in them due to the absorption of more energy. In this research, by using the laboratory results of a short column subjected to lateral reciprocating loads, an attempt was made to select the most optimal state with the help of steel sheets covered with different shape patterns. For this purpose, to determine the effect of retrofitting on the short column, six different installation modes of the proposed steel cover were used in abaqus software for finite element analysis. Next, the studied short column was subjected to reciprocating cyclic loading according to the standard pattern. The results of this research show that retrofitting a short column with an integrated steel sheet is able to increase the seismic resistance of the column by 49%, but the most optimal retrofitting method in terms of strength and volume of steel used is the retrofitting method with model-2 installation pattern.
