摘要

A new method of concrete reinforcement is proposed in this experimental study. The behaviour of three shear wall specimens that were reinforced with steel perforated plates was investigated under cyclic semi-dynamic loads. The main parameter was the volumetric ratio of reinforcing steel. The other parameters were similar in all of the walls. Bending strength was calculated using the concrete beam bending theory according to ACI code and was compared with experimental results. The Experiment shows 30 percent increase in ultimate bending strength. Hysteresis diagram of the specimens indicates considerable energy absorption capacity of the walls reinforced with perforated plates. Also, the walls were capable of carrying loads to high deflections. This system of reinforcing shear walls provided good performance based on strength and ductility.
