Performance Analysis Of New Precast Concrete Shear Wall

With the popularity of China’s urbanization, the country is facing a lot of demand for new housing. In short, how to quickly solve the housing problem of residents imminent. Conventional low-situ reinforced concrete shear wall structure level of industrialization, the slow progress of construction, the construction site of serious pollution, the huge consumption of resources is not conducive to the sustainable development strategy of the country.February 21, 2016, the State Council on Several Opinions of the urban planning and construction management to further strengthen the work of the proposed: the promotion of prefabricated buildings to encourage construction companies Prefabricated construction, the construction site to reduce the generation of pollutants. Government to increase incentives to develop the assembly building design, construction and acceptance. Implement housing industry is the best way to solve the current problem. Fabricated shear wall system is the most widely used building prefabricated structures form, the researchers have a certain research value of prefabricated shear wall system.Node connection is the core technology of prefabricated shear wall system, the paper proposes a new form connection fabricated shear walls, the construction can improve efficiency and reduce the cost of the project. Using ABAQUS finite element software simulation based on their connections. By applying lateral cyclic loading on the shear specimen analysis skeleton curve of the new member, hysteresis curve, stiffness degradation curve, yield load, yield displacement, ultimate load, energy dissipation capacity, ductility and other properties. The following conclusions:(1) in-situ shear test and finite element simulation of consistent performance in situ shear hysteresis curves, skeleton curves, stiffness degradation curve characteristic curve aspects.(2) under low cyclic loading effects, although the new shear wall structure assembled in situ shear energy dissipation capacity compared to slightly weaker, but close to the cast wall structure, exhibit relatively good mechanical performance to meet the structural requirements.
