新型裝配式型鋼剪力墻組合結(jié)構(gòu)抗震性能研究
[Abstract]:At present, with the development of urbanization in China, the demand for new housing is increasing. Clearly, this will not change for decades to come. Because of the high population density and the shortage of land resources in cities, it is difficult to imitate the urbanization pattern of developed countries in Europe and the United States in a short period of time. To build multi-storey houses or villas to meet the housing needs. At present, the development mode of urbanization in China is still to expand the scale of the city and absorb the new city people. How to meet the housing needs and maximize the utilization of limited urban land resources is an urgent problem to be solved. Under this trend, speeding up the construction of high-rise residential clusters should be a reasonable choice for the development of most cities in China for some time to come. From the point of view of building structure research, it is a way to solve this contradiction to develop a high-rise residential building system with low pollution and low cost, which can make use of resources more effectively and build a better quality high-rise residential building system with low pollution and low cost. The assembled steel shear wall composite structure studied in this paper is a kind of structural system for high-rise residential buildings, which was proposed by Beijing Architectural Design and Research Institute Co., Ltd. This paper mainly introduces the research contents of three related experiments. The full text is divided into six chapters, including: (1) introduction. This paper expounds the present situation of housing industrialization in China, and explains the necessity of developing assembled structure housing. This paper introduces the research situation of assembled structure, especially the assembled shear wall structure at home and abroad. Finally, the main contents of this paper are listed. (2) the seismic performance test of the new assembled integral wall. This experiment consists of two groups of walls. The first group of tests examined the seismic performance of the dry connection at the vertical joint position of the walls, while the second group tested and tested the edge-constrained members of the section steel. High strength grouting material post-pouring belt and post-cast steel shear bond connection performance. (3) pseudo-static test of assembled integral steel shear wall composite structure. Through the introduction of the design, fabrication, assembly and quasi-static test of the test model, the construction technology of the structural system is summarized, and the strength, stiffness, ductility and energy dissipation of the structure are investigated and studied. (4) pseudo-static test of prefabricated steel shear wall with bolted connection. Four groups of quasi-static tests were designed to investigate the seismic behavior of bolt-joint joints in horizontal joints of wall pieces. The bending and shear properties of prefabricated shear walls connected with pre-embedded bolts were tested respectively, and the strength and stiffness of the test body were obtained. Ductility and energy dissipation performance parameters. (5) conclusion and prospect. This paper summarizes the experience and deficiency in the process of experiment, puts forward some suggestions, and provides some ideas for the follow-up research.
