| Glulam material has gradually been widely recognized by all walks of life thanks to its advantages of reproduction,materials saving,environment protection and green lowcarbon.Its field of application changes from low-rise building to high-rise building.In order to promote the application of timber work in high-rise building,this thesis studies the seismic capacity of shear wall with glued timber structure by three groups pseudostatic testings with 9 specimens and finite element analysis.The main contents of the research are as follows:(1)Experiment on physical and mechanical properties of glued laminated timber.(2)The design of shear wall with wood structure by using the advantages of glued laminated timber.(3)The influence of axial compression ratio,number of supporting members and size of beam-column on the performance of wood structure shear wall.The main conclusions in this study are as follows in the experimental results and finite element numerical simulation and theoretical analysis:(1)Compared with the raw material,the glued wood material shows good performance in physics and mechanics.(2)Sway rod can share part of horizontal shear and transform it into axial force,and then give full play to the superior tensile and compression properties of glued laminated timber so that the shear strength,elastic lateral stiffness and hysteretic energy dissipation of the wall are greatly improved.(3)It uses ABAQUS to analyze the four kinds of supporting system of wood structure shear wall model by finite element method,and the analysis results show that the structure of shear wall system is reasonable,the simulation results are basically consistent with actual stress state with high degree of coincidence. |
