Experimental Study on Seismic Behavior of Strengthening Joints in Light Steel Adding Storey
In order to acquire the seismic performance of three different types of nodes between the concrete frame and the light steel adding storey, the pseudo-static tests were carried out to analyse contrastively these specimens’ failure modes, stiffness degradation, hysteretic curves and energy dissipation. The test results showed that : Three nodes’ destruction were due to the plastic hinges emerging at the end of beam; both encased steel and carbon fiber strengthening method can improve the seismic behavior, and in terms of the ultimate bearing capacity, energy consumption ability, the encased steel strengthening one can improved more significantly, and the encased steel one can effectively slow down the speed of stiffness degradation.
