Force Mechanism

Two different kinds of steel-encased concrete composite beam connected concrete filled low-cycle reversed loading. The test results indicate that the two joints both have higher bearing capacity, better ductility performance and seismic behavior. In order to theoretically analyze the joints force mechanism, the nonlinear finite element analysis (FEM) of the above two joints has been conducted by using the ANSYS program. According to the results of FEM, the hysteretic curves and the skeleton curves are deduced. And from the contrast between the test results and the finite element results on energy dissipation capacity and ductility, it indicates that the theoretical results and the experimental results are basically coincident. But the errors of them are occurred due to the difference of material constitutive model. The precision of the nonlinear finite element analysis of reinforced concrete is depending on the constitutive relation of concrete to a large extent.

Based on experiment of two mixed frame with SRC columns and steel beam under low-reversed cyclic loading, hysteresis behavior, ductility, energy dissipation are studied. The test results show that the mixed frame with SRC columns has better seismic performance. The nonlinear finite element analysis on the seismic behavior of the frame specimen was conducted using Openness developed by the Pacific Earthquake Engineering Research (PEER) Center. The calculated results are much coincided with the tested results.
