【摘要】 从框架-剪力墙结构协同工作的连续化分析原理出发,建立了在水平荷载作用下考虑剪力墙剪切变形影响时的平衡微分方程.按照我国现行高层建筑混凝土结构技术规程(JGJ 3-2002)和建筑抗震设计规范(GB 50011-2001),推导了考虑剪力墙剪切变形影响时满足层间侧移角限值的抗震剪力墙计算公式,并将其与未考虑剪力墙剪切变形影响时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点与不同点.然后引入了各种修正系数,通过图表探讨了剪切变形系数对剪力墙合理数量的影响.最后给出算例,反映出系数对计算结果的影响程度,并分析了引起差异的原因.该方法简单实用,可用于高层建筑结构的初步设计阶段.更多还原

【Abstract】 Based on the principle of the continuous analysis of interactive frame-shear wall structures,a differential equation of equilibrium was established for frame-shear wall structures in consideration of shear deformation of shear wall.According to the current Chinese technical specification for concrete structures of tall buildings(JGJ 3-2002)and the current code for seismic design of buildings(GB 50011-2001),a series of formulas taking shear deformation of shear wall into account was deduced strictly from the allowable horizontal rotation under various load actions.Furthermore,the similarity and difference in determining the optimal quantity of shear walls in frame-shear wall structures between considering and not considering shear deformation of shear walls were analyzed.When various correction coefficients were inducted,a series of diagrams was given,and the effect of the shear deformation coefficient of the shear wall on the optimal quantity of shear walls in frame-shear wall structures was discussed.Finally,an example was given to show the effect of the coefficient on the optimal quantity of the shear walls,and the reason for the difference in the optimal quantity of the shear walls was analyzed.It has been proved that this method is accurate and convenient for the preliminary stage of tall building structural shop drawing design and the final stage of censor.更多还原
