| 摘 要： | 通过两榀单层单跨混凝土框架在竖向荷载下的试验研究和非线性有限元全过程分析,对"梁强于柱"和"梁柱等强"框架的极限荷载、正常使用状态下的变形、位移延性和塑性内力重分布进行了研究.研究结果证明,在配筋适当的情况下,"梁强于柱"和"梁柱等强"框架在正常使用荷载下裂缝宽度和挠度均能满足混凝土结构设计规范的要求,且均具有较好的延性,能实现充分内力重分布.

| Abstract: | Through the test of two concrete frames under vertical load and nonlinear finite programme analysis,the performances of strong beam with weak column and equal strength column and beam are studied,such as ultimate load,deflection,displacement ductility,redistribution of internal force.When the reinforcement is proper,the research proved that strong beam with weak column" and "equal strength column and beam" have better displacement ductility and can realize full redistribution of internal force,the width of cracks and deflections can satisfy the rules of code for design of concrete structures. |

| Keywords: | concrete frame strong beam with weak column equal strength column and beam displacement ductility redistribution of internal force |
