某高层住宅剪力墙结构设计探讨

Design of Shear Wall Structure in a High Rise House

依托三亚红沙棕榈滩地块住宅项目中的高层住宅结构设计,从水平荷载特点、规范要求、计算环节和施工图环节出发,总结类似结构的主要特点以及设计中的注意事项。首先总结风荷载控制与地震荷载控制的剪力墙结构的设计区别、影响荷载取值的关键因素以及对钢筋强度的选取;其次,结合规范要求的位移、位移比、周期比、墙体稳定的限制,分析剪力墙布置的原则和方法以及明确6度区短肢剪力墙与剪力墙的区别与构造要求,提出减少短肢剪力墙布置的原则。另外,通过住宅单体的整体计算模型和嵌固层以上计算模型的计算分析对比,得出单体整体计算模型能满足设计精度要求。同时,对窗连梁采用高矮连梁两种做法进行分析比较,得出优先选用节省材料的矮连梁做法的结论以及明确四级剪力墙结构的构造边缘构件构造要求,指出通过精细的边缘构件设计和采用适当的楼层归并来进行梁配筋可以有效减少结构的钢筋用量。希望通过设计总结为类似结构设计提供参考。

This paper relies on the high-rise residential structure design of Sanya red sand beach plots of residential projects summarized the main features of the structure from the load analysis,the specification requirements,the calculation links and the construction drawings.First,the difference between the wind load control and the seismic load control wall structure design,the key factors and the selection of the strength of the steel bar were discussed.Secondly,according to the requirements of displacement,displacement ratio,cycle ratio and wall stability limit,the principles and methods of shear wall layout were analyzed.In addition,through the calculation analysis and comparison of the overall calculation model of the residential monomer and the above calculation models of the embedded layer,it was concluded that the overall calculation model of the monomer can meet the design accuracy requirements.In addition,the window lintel beams using height two methods of analysis and comparison,the preferred material saving short beam approach and a clear conclusion structure edge member structure four stage shear wall structure,and pointed out that the design of fine edge members and adopt the appropriate floor merge can effectively reduce the beam reinforcement of reinforced structure.It is hoped that the design summary of this paper can provide reference for similar structure design.
