摘要
冷拔丝预应力圆孔板是广泛使用的结构构件,因钢丝材质较脆、钢丝与混凝土的粘结强度低、又曾发生过脆断事故,它的结构性能一直是工程界关心的问题。本文从理论分析和试验研究两方面论述冷拔钢丝预应力圆孔板的结构性能,并定量地给出了延性指标。
The cold drawing wire prestressed concrete slab with circle hole is widely used as a structure member. Because wire is relatively brittle and its bond between wire and concrete is low. In addition, some brittle collapses of the slabss often accurred. Its structural capability is deeply cocerned in engineering. The paper discusses the structural capability of the slabs with circle hole from both the aspects of the theory and experiment and gives guantitative ductility index.
