摘要
针对采用钢绞线进行加固的混凝土板,采用合理假定,分析了混凝土开裂阶段、受力钢筋屈服阶段和混凝土压碎阶段的应力状态,得出了这3个阶段基于延性破坏时的受弯承载力的理论表达式,通过试验验证了上述理论分析结果的准确性。
Aiming at the concrete slab reinforced by steel wires,on the basis of reasonable assumptions,three typical stress states of concrete cracking stage,steel bar yielding stage and concrete crushing stage are analyzed.The theoretical expressions of flexural capacity under the three stages are drawn based on the ductility flexural criterion.The accuracy of the theoretic analysis is proved through actual experiment.
