均布荷载及集中荷载作用下框-剪结构中剪力墙的合理数量
|
摘要
根据框架-剪力墙结构的受力特点,提出了在均布荷载及集中荷载作用下确定剪力墙合理数量的方法.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JGJ3-2002《高层建筑混凝土结构技术规程》和GB50011-2001《建筑抗震设计规范》,严格推导了在这两种荷载形式作用下,框架-剪力墙结构满足层间侧移角限值的抗震剪力墙的计算公式.分别给出了在不同抗震等级、场地类别和设计分组情况下的剪力墙合理数量图,列出了计算剪力墙合理数量的步骤,讨论了影响剪力墙合理数量的各种因素.方法简单实用,可用于高层建筑结构的初步设计与结构施工图的审查.
According to the characteristic of force which frame-shear wall structures are suffered, a method for determining optimal numbers ofshear walls under top concentrated load and uniform load is proposed. Based onthe principle of continuous analysis of interactive frame-shear wall structuresand current JGJ 3-2002, Chinese technical specification for concrete structures of tall building and current GB 50011-2001, code for seismic design of buildings , a series of formulas are deduced strictly from the allowable horizontal rotation under top concentrated load and uniform load.Furthermore, the figures that show the optimal number of shear walls in frame-shear wall structures and uniform load under various ground categories, anti-earthquake grades and designgroups are separately given, the process to caculate the optimal number of shear walls is listed and some kinds of influence factors are discussed.This method is accurate and convenient enough for use when tall buildings are designed during the preliminary stage of design and structural shop drawings are censored during the final stage of censor.
