Performance Evaluation and Shear Resistance of Modular Prefabricated Two-Side Connected Composite Shear Walls

This paper investigates the impact of configuration parameters on the seismic performance of the modular prefabricated two-side connected composite shear wall. Firstly, the finite element model of the modular prefabricated two-side connected composite shear wall was established and validated by Xu’s experimental results. Secondly, three aspects of parameter investigations were discussed in detail based on the validated numerical technology, namely the design parameter of ISP, design parameter of the stud, and design parameter of reinforced concrete faceplate (RCF). Then, the computation formula of shear capacity is deduced on the basis of the finite element model for reference to structural design. The results of parameter analysis displayed that the seismic performance of the modular prefabricated two-side connected composite shear wall has excellent seismic performance with the array studs of the length-diameter ratio of 4 which the center distance of 150 mm, and RCF with the thickness of 75 mm. A satisfactory but unadventurous estimation of the shear capacity of a modular prefabricated two-side connected composite shear wall is supplied by the advised technique
