Experimental Research And Theoretical Analysis On The L-shape Connection Of The CS Panel Structural System

The focus of this article is the test research and theoretical analysis on the basic mechanics and seismic performance of the L-shape connection in the CS panel structure model. The experiment research on the L-shape connection was carried out in the integral building model test. Four L-shape connections were made, and two of the four L-shape connections were made of concrete and the others employed section steel. By exerting low reversed cycle loading to the overall building model, we made detail observation to the experiment phenomenon on the connection of the two type L-shape during the test, still, we carried out measurement on the distribution and changes of the node column's stress and strain,at last, the service performance analysis was carried out to those L-shape connections. In the end of the article, we made a pushing calculating analysis to model structure, and inspected the influence of the node column to the overall structure's service performance.The experiment and theoretical research shows that the L-shape connection made in section steel can extremely strengthen the stiffness and extension of entire structural system. The connection between section steel column and wall is steady by the steel link-bar. So the connection made of section steel is better than that made of concrete in aspect of mechanics, heat preservation and insulating.
