Structural Design for Shear Wall Structure with Composite Reinfoced Concrete Wall of Tall Building

高层预制钢筋混凝土叠合剪力墙结构的设计包含许多新的设计内容。目前尚无配套的设计规范及计算分析软件。通过在研究预制钢筋混凝土叠合剪力墙试验资料的基础上,采用了两种设计方法。方法一是将PC和PCF作为结构的外加荷载进行结构的强度设计,但考虑PC及PCF构件的刚度对结构周期以及主要计算参数的影响。方法二是在进行结构的刚度分析,控制结构位移时,将PC和PCF作为结构的构件,以此计算结果作为控制结构刚度的依据。运用上述两种方法将结构简化后,仍采用现行的计算软件进行结构分析。通过实际工程的计算结果,可以看出,这两种方法在满足现行设计规范的同时也优化了高层预制钢筋混凝土叠合剪力墙的结构设计。

The structural design for shear wall structure with composite reinfoced concrete wall of tall building includes many new contents.There are still no suit design codes and computer softwares to use for the designers.Based on the analysis about some mid-rise experiments on composite reinfoced concrete walls,the two design methods are offered by the author.In the first case,the PC and PCF are considered as the loads of the structure.Considing the effects of PC and PCF on period of the structure and some parameters of calculation,the design of the strength is according as the results of the calculation.In the second case,the PC and PCF are considered as members of the structure when calculating the stiffness of the structure.The structure is simplified,and can be analysised by the softwares which are generally accepted in structural design.The resurlts of the design calculation are both fitted with the design codes and rule of the optimum design for the shear wall structure with composite reinfoced concrete wall of tall building.
