摘　　要：在传统冷弯薄壁型钢结构体系的基础上,从模块化、装配化角度出发,提出了一种适用于低层村镇住宅的新型结构体系——模块化冷弯薄壁型钢结构体系。首先,简述了墙体模块单元的构成,给出了7种通用标准化墙体模块单元,并介绍了基于通用标准化模块单元的村镇模块化户型构建原则及过程;其次,详述了便于快速装配安装的标准墙体单元间模块化连接方式,对模块连接节点进行了受力分析及数值模拟,并给出了模块化冷弯薄壁型钢结构体系构建的原则;最后,重点介绍了适用于所有冷弯薄壁型钢结构体系的抗剪墙长简化设计方法以及基于模块化冷弯薄壁结构体系的抗剪墙长设计方法,并通过实际案例详述了墙长确定过程,同时对比了不同计算方法的抗剪墙长,进一步验证了所提出的抗剪墙长简化设计方法的可行性。结果表明:所提出的模块化冷弯薄壁型钢结构体系可大幅提高冷弯薄壁型钢结构低层村镇住宅的工业化和产品化水平,大幅缩减了工期;所提出的抗剪墙长简化设计方法可显著降低设计门槛,便于该类体系的推广应用。Based on the traditional cold-formed thin-wall steel structure system,from the perspective of modularization and assembly,a new type of structural system—modular cold-formed thin-wall steel structure system was proposed,which was suitable for low-rise village houses.First of all,the composition of the wall module unit was described briefly,seven kinds of general standardized wall module units were given,and the construction principle and process of village modular house based on the general standardized module unit were introduced.Secondly,the modular connection mode between standard wall units,which was convenient for rapid assembly and installation,was described in detail.The force analysis and numerical simulation of the module joint were carried out,and the principle of the construction for modular cold-formed thin-wall steel structure system was given.Finally,the simplified design method of shear wall length applicable to all the cold-formed thin-wall steel structure systems were emphatically introduced,and the design method of shear wall length applicable to modular coldformed thin-wall structure systems were also emphatically introduced.The determination process of wall length was detailed described through a practical project,and the shear wall length with different calculation methods was compared,so the feasibility of the proposed simplified design method for shear wall length was further verified.The results show that the proposed modular cold-formed thin-wall steel structure system can greatly improve the industrialization and productization level of low-rise village residential buildings,which can also greatly reduce the construction period.The proposed simplified design method of shear wall length can significantly reduce the design threshold,which is convenient for the popularization and application of this type of system.
