Test and bearing capacity calculation of fabricated shear wall based on strong horizontal joint and weak vertical joint
The design method of"strong horizontal joint and weak vertical joint"for fabricated shear wall structure was proposed.Three types of specimens(rectangle shape,T shape,L shape)were designed.Low cyclic loading tests were carried out under different coaxial pressure ratios(0.1,0.3),and the bearing capacity and ductility property of the specimens were studied.The results show that the fabricated shear wall structure has good mechanical properties.The dampers yield and dissipate energy,which improves the seismic performance of the structure and plays a good role in connecting the wall limbs.The strain distribution law of specimen section was discussed,the simplified mechanical calculation model was established,and the calculation formula of ultimate bending capacity of fabricated shear wall structure was put forward.
