Abstract:
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 cold-formed 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.
