Resumo: | The BubbleDeck type slab (BD) is a reinforced concrete (RC) flat slab that includes recycled plastic hollow spheres (RPHS) in its core for decreasing its dead weight. However, punching capacity of BD slabs can be a critical aspect, thereby this work is devoted to assess experimentally its punching behavior. An experimental program composed of four real scale prototypes, representative of RC flat slabs in punching loading conditions, was carried out. Two of these slabs are of BD type, while the other two do not include the RPHS system, herein denominated as RC solid slab (SS). The test results show that all the tested slabs failed in punching after the occurrence of yield initiation of the flexural reinforcement. The punching capacity and the deflection at failure of BD type slab has decreased up to 14% and up to 44%, respectively, when compared to the corresponding SS type slab. A relatively small ductility index was obtained (between 1.51 and 2.65). In BD type slabs, the punching failure surface had tendency to propagate through the RPHS, at an inclination angle of about 45 |
