MECHANICAL PROPERTIES OF A NEW FULLY PREFABRICATED STAGGERED FLIP-DOWN SLAB

Prefabricated slab has been widely used in the global construction industry due to energy saving, environmental protection, and good economic advantages. In this paper, a new type of fully prefabricated staggered flip-down without cast-in-situ operation proposed. First, experiments were carried out on slab. The structural performance was compared with slabs composite same specification. experimental results showed that ultimate bearing capacity meets requirements for practical utilization. On basis, an additional CFRP sheet could be pasted bottom initial seam between enhance integrity prevent cracks. Then, whole loading process simulated, consistent results. Finally, through parametric analysis, recommendations improvement put forward mechanical properties kind
