【摘要】 首先从框架-剪力墙结构协同工作的连续化分析原理出发,按照我国现行高层建筑混凝土结构技术规程和建筑抗震设计规范,严格推导了刚接体系满足层间侧移角限值的抗震剪力墙的计算公式,并将其与铰接体系的计算公式进行比较,分析了它们在确定剪力墙合理数量上的相似与不同.然后讨论了影响连梁等效约束刚度的各种因素,接着引入了各种修正系数,通过图表探讨了对剪力墙的合理数量的影响.最后给出算例,反映了对计算结果影响的程度,分析了引起差异的原因,并提出了合理化建议用以指导工程实际.更多还原

【Abstract】 <Abstrcat> Based on the principle of continuous analysis of interactive frame-shear wa ll structures and current Chinese technical specification for concrete structure s of tall building and current code for seismic design of building s, a series of formulas for rigid connection system which are compared with hinged connection system are deduced strictly from the allowable h orizontal rotation under various load actions in this paper.Furthermore, the sim ilarity and difference in determining the optimal quantity of shear in frame-sh ear wall structures between rigid connection system and hinged connection system are analyzed.Then some kinds of effect factors of the equivalent restrained rig idity of connecting beam are discussed.According to inducting various correction coefficient, a series of diagrams were given, and the effect of the equivalent restrained rigidity to the optimal quantity of shear in frame-shear wall st ructures are discussed.Finally,an example is given to discuss that how much degr e e the influence of equivalent restrained rigidity to optimal quantity of shear wall is,and the reason for the difference in the optimal quantity of shear wall is analyzed,some reasonable suggestions are brought forward in engineering pract ice.更多还原
