摘　　要：运用受弯构件全过程数值分析计算程序,在预应力混凝土空心板截面尺寸及荷载形式相同的情况下,对预应力混凝土空心板进行受力全过程的数值分析,即采用计算机模拟试验的方法,探讨了跨高比对中强螺旋肋钢丝预应力混凝土空心板延性影响的总体规律。In this paper, under the condition of unchanging section sizes of precast prestressed concrete slab and forms of loading, the numerical simulation calculation procedure of member in bending is used and the whole numerical Valne process of precast prestressed concrete slab stress is analyzed. In other words,the computer simulation experiments is performed and study the whole influencing law of span - height ratio to the ductile property of precast prestressed concrete slab with mid - strength spiral - rib steel wire is studied.

关 键 词：跨高比 中强螺旋肋钢丝 预应力混凝土空心板 延性破坏
