EXAMINING THE EFFECT OF SHAPE, SIZE AND DISTANCE OF POPS IN THE NON-LINEAR BEHAVIOR OF STEEL SHEAR WALLS

Abstract

The shape and place of the holes of shear walls are effective on tensions and the elastic and non-elastic transformation and also the formability, bending resistance and capacity of absorbing energy at times of earthquakes. Thus, it is necessary to pay attention to the non-linear behavior of steel shear walls with pops and consider some strategies for reinforcing the sides of the pops. The goal of this project is studying and deeper understanding of the strength and weakness points of pops, the effect of shape and place of pops on the functioning and behavior of shear walls in the non-linear area of steel shear walls. For this purpose, we present the results of a numeric study on steel shear walls with pops. The analyses are done by the limited components Abaqus program and are calibrated by experimental results. An area of subjects that is studied in the steel shear walls with pops includes final load, and load-displacement curves. The numeric results for steel shear walls with pops would also be compared. Finally, the calculated numeric results will be compared with the experimental results. Final load and load-displacement curves gained by the numeric analysis show a good adaptation with the results gained from related experiments. Results of numeric analysis in most cases indicate that this method is a conservative one. Thus, we could use this method in designing applications.
