Resistance Performance

According to arrangements of local cast-in-situ regions, new precast concrete shear wall (NPC wall) has various types including integrally precast component, component with precast concealed columns and local region of wall by casting in situ, component with precast one end concealed column and the other end by casting in situ and component with all cast-in-situ concealed columns. By finite element analysis for four types of NPC wall and comparing with monolithic cast-in-situ finite element model, the lateral resistance performance of each type of NPC wall were discussed. Compared with cast-in-situ finite element model, NPC wall has rather different lateral resistant mechanism, the load-displacement curves are obviously different, and the horizontal and vertical connections decrease the strength and stiffness. The reasonable arrangement of local cast-in-situ regions can effectively improve the lateral resistance performance of NPC wall. The model composed of all cast-in-situ concealed columns, which has similar lateral resistant performance to cast-in-situ model and shows reasonable load mechanism, should be recommended. Meanwhile, the model consisting of precast concealed column and local cast-in-situ region of wall should be avoided for its poor performance.

Composite Shear

A new composite structure system is proposed in this paper to suit the demand of building energy conservation and heat preservation. Based on the low reversed cyclic loading test, the non-linear finite element (FEM) analysis model of composite shear wall is established by ANSYS so as to study crack status, stress variation characteristics and failure process under the action of horizontal loading. The results of ANSYS finite element analysis show good agreement with the test results.

Reinforcement Scheme

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2~3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.
