Review on Stamping Shear Properties of Foam Board

Bubbled slabs are introduced to decrease the self-weight of the slab by decreasing the amount of concrete in the slab's middle. This decrease results in cost savings, a reduction in the time needed for construction, improvements in structural performance, and an increase in the slab's efficiency. Despite the many benefits that this form of slab offers, it is similar to flat slabs. The more concentrated load at the column connection causes it to experience failure-punching shear. In addition, the design equations for bubbling slabs suggested by building rules derive from experiments conducted on flat slabs. Previous investigations of bubbled slabs have shown that the punching shear of bubbled slabs is different from that of flat slabs.
