Experiment on Seismic Performance of Steel Frame-Grouting Light Steel Shear Wall Structure
The horizontal low cyclic reversed loading test of full-scale steel frame-grouting light steel shear wall structure is carried out,the coupling effect of grouting light steel shear wall and steel frame is studied,and the failure mode,stress characteristics and energy dissipation mechanism of the structure are analyzed.The bearing capacity,lateral stiffness,ductility and energy dissipation capacity of the structure are obtained.Compared with the test results of pure steel frame and cold-formed thin-walled steel grouting wall,it is found that the grouting light steel shear wall is connected with steel frame by self-tapping screw,and the two have good cooperative performance.The shear bearing capacity and lateral stiffness of frame-shear structure are 1.50 times and 1.64 times of the sum of steel frame and wall respectively,the ductility coefficient of structure is 5.42,and the seismic performance is excellent.The research results can provide a scientific basis for the design and research of this kind of structures.
