排钢管钢板混凝土剪力墙转钢管混凝土剪力墙体系设计方法及应用
Design method and application of transformation of shear wall with paralleled steel tube columns and steel plate-confined concrete to shear walls with steel tube-confined concrete
【摘要】 针对下层排钢管钢板混凝土剪力墙转成上层内置钢管混凝土(STCC)剪力墙结构体系,提出系统的截面转换设计方法。基于刚度等效原理进行上层STCC剪力墙设计,在初步设计截面基础上,使用穷举法以经济性为目标对上层STCC剪力墙截面进行优化。通过一超高层建筑实例采用本方法进行转换截面设计,利用ABAQUS建立该优化后的剪力墙有限元模型,进行承载力复核验证,结果满足承载力要求,且使造价相比优化前减少27%。该转换截面设计方法可为一般钢板混凝土剪力墙转内置型钢混凝土剪力墙的截面转换设计提供参考。
【Abstract】 A systematic design method for the transformation of the lower shear wall with paralleled steel tube columns and outsourcing steel plate-confined concrete to the upper shear walls with steel tube-confined concrete(STCC) is proposed. The design of the upper STCC shear wall is based on the principle of stiffness equivalent. On the other hand, the exhaustive method is used to optimize the section of the upper shear walls with steel tube-confined concrete, and a better economic benefit is obtained. Then, through a super high-rise building example, this method is adopted to design the transition section and ABAQUS is used to establish the optimized finite element model for the verification of the bearing capacity. The result meets the bearing capacity requirements, and the cost is reduced by 27% after optimization. The conversion section design method proposed in this paper can provide a reference for general outsourcing shear walls to shear walls with steel tube-confined concrete.
