Comparative Study Of Prefabricated Shear Wall Structure Of Vertical Connections

Currently,with the rapid development of China's economy,in particular,the concept of sustainable development in depth.Built in the form of prefabricated concrete with low-carbon,green,environmental protection,energy-saving features such research is gradually warming.Way to achieve the construction of industrial and civil buildings fundamental shift,Not only implement national industrialization and building housing industry overall deployment,but also the transformation of economic development,improvement of the objective requirements of residential and livelihood conditions.Prefabricated shear wall structure is a senior-oriented form of high-rise residential housing construction,most of its members in the factory prefabricated,assembled at the construction site.Situ shear wall structure than the more energy-saving construction methods and materials,shorten the construction period,with a broad space for development.Therefore,in our prefabricated concrete structural system development,it occupies an important proportion.And this paper,the use of the sleeve were prefabricated vertical shear wall structure connected with far-reaching significance.In this paper,the use of a sleeve assembly type specimen vertical shear wall structure connected to low cyclic load under quasi-static test,the main content is divided into the following four chapters are as follows:(1)The housing industry through domestic and international situation,the advantages and disadvantages of prefabricated concrete structures introduced,compared to the existing prefabricated concrete shear wall vertical connection form describes the analysis.(2)the ability to study the use of carrying capacity and seismic performance of the sleeve connection,and in order to investigate the use of different sleeve diameter,fabricated shear wall structures of different pitch connector sleeve reciprocating loads in energy dissipation capacity under low cycle,the design of the three shear test specimens.(3)Based on three specimens of quasi-static test,the test results showed that:after testing found that the use of shear specimens sleeve sleeve connection is not more quantity,more quantity,etc.on behalf of the steel shear walls seismic performance,the better;the more the number of the sleeve,the sleeve joint stiffness greater the mutation is not conducive to the earthquake.(4)Experimental models using ABAQUS software for the numerical simulation,the simulation results were compared with experimental results,the analysis shows,from the destruction of form and capacity,energy consumption and other characteristics are consistent with the experimental results.
