摘　　要：通过对 PK 预应力混凝土双向叠合楼盖的加载试验,研究了 PK 预应力混凝土叠合板的挠度、抗裂及双向受力性能,试验表明该叠合板具有良好的抗裂性能和整体性能,双向受力特征明显,可按整体双向板进行设计和计算;并根据试验数据分析了 PK 双向叠合板中荷载的传递规律,得出 PK 预应力混凝土双向叠合板的荷载传递规律基本满足现行规范要求。On the basis of the loading tests of the PK prestress concrete two-way composite floor , the deflection,anti-checking and two-way strength performance have been studied. The text indicate that the composite floor has excellent bulking property and cracking resistance, and two-way strength performance is obvious, so it is designed as two-way slab ; Based on the test data, the loading -transferring rules of the PK two-way composite slab were analyzed also and it was obtained that such loading-transferring rules satisfied the present criterion.
