Abstract
In the present study, four set of full scale specimens have been cast to investigate the effects of handmade GFRP shear bands on punching behavior of single footings. To do so, the specimens’ reinforcement was designed so that the punching failure governed. Besides, two types of concrete mixture, i.e. normal concrete (NC) and self-compacting lightweight concrete (SCLC) were used. Five Linear Variable Differential Transformer (LVDT) sensors have been installed on each specimen to record settlement as well as deflections. Moreover, the amounts of strain of bars and shear bands, caused by loading, at the edge of baseplate and two-way shear critical section have been recorded by installing strain gauges. The results show that the use of GFRP shear bands results in the increase of cracking resistance, maximum tolerable deflection, and recorded peak loads. In addition, it led to an increase of failure time which could warn occupants before complete failure.
