Study On A New Technology Of The Connection Between Vertical And Horizontal Wall In Prefabricated Shear Wall Structure

In prefabricated shear wall structure, theconnection between vertical and horizontalwallin the prefabricated shear wall structure plays an important role on the mechanicalproperties of the whole structure. This paper introducesseveral connections betweenvertical and horizontal wall in the current domestic, aiming at improving the performanceof the connecting technology, we design a new-type connection between vertical andhorizontal wall. The main research work and achievements are as follows:Using the concrete filled steel tube in the connection area for the new connection asthe core design, the connection of longitudinal and lateral wall model in a shrinkage scaleis manufactured to carry out the quasi static test. This is for analyzing the model’sexperimental data to evaluate carrying capacity, hysteretic characteristics andcircumstances of energy consumption.The finite element analysis software is utilized to get the result of the loads in theory,compare the numerical solution and the experimental solution, fitting the result in theoryand practice, study on the main factors which have effect on mechanical properties of theconnection. The theoretical foundation is prepared for the further study of new-typeconnection.Based on the energy balance principle, the linear static alternate path method is usedto obverse the pipeline of the spare stress of the damaged structure. According to the study,the vertical carrying reserve of fabricated shear wall structure can be provided by thenew-type vertical seam connection, the capacity of anti-progressive collapse of buildingstructure can also be improvedin occasional loads.
