The shear wall as the most commonly elements used in the current residence, Promotingthe wide application of prefabricated shear wall structure is an important role which willdeepen development of housing industrialization in our country. The reliability of theconnection between the shear wall is the key to the seismic performance of the wholestructure for most of the structure types, it also treat as the key to the application. Thisarticle systematically analyze the traditional connection system, it is proposing to designa new connection which machine steel as U model to finish connection. The Purpose isto improve the traditional connection structure which is complex, higher accuracy forpromotion of defects, and finish the experimental research on the seismic performance.Though pseudo-static test of2levels prefabricated shear wall connected nodes and2with the combination of the composite floor slab connected nodes to specimens ofanalyze specimen features such as submission, destruction, the connection of stresstransfer and stress distribution features such as complex connection district. Theexperimental results showed that the damage form of specimens for shear wall bendingshear failure, Yield failure process consists of longitudinal reinforcement, fractures, theexpansion of cracks, concrete phenomena. The stress transfer effect is normal in thewhole test. The specimen showed a good effect of energy consumption. This articleadopts the way of connection can be used as a reliable connection technology applied inengineering practice.This paper, by using ANSYS software to complete the four specimens of thenonlinear finite element numerical calculation and analysis, finite element calculationresults and test results is good, for the nonlinear analysis of prefabricated shear wallprovides analysis method.This article through to the comprehensive assessment of test results and finiteelement calculation results for the introduction of complex nodes stress distribution andfracture development of composite floor slab are analyzed, results show that theultimate bearing capacity of the composite floor for the whole specimen, it exist distincteffect on the mechanical shape such as stiffness, and assembled in the future for thedesign of the shear wall structure rationalization proposal is put forward.
