Abstract:
Three reinforced concrete columns with multiple composite stirrups were designed and manufactured, and the reversed cyclic lateral loading tests were carried out. Based on Mander model and modified Kent-Park model, the constitutive model of concrete was established under different constraints and OpenSees software was used to perform the finite element analysis. Compared to the test results, it verified the constitutive relation of concrete with multiple composite stirrups and the rationality of frame column modeling. The finite element analysis model of reinforced concrete complex frame structure with multiple composite stirrups was established, and history response analysis was performed. The results show that the hysteretic curves of three groups of columns with multiple composite stirrups are relatively full bow-shaped, showing good plastic deformation behavior and energy dissipation capacity. The peak load of the finite element simulation results is close to the experimental results, and the shape of hysteretic curves agrees well with the experimental results. The finite element model can be used to accurately analyze the mechanical behaviors of this kind of composite reinforced columns. The peak displacements of complex frame structure are the largest under the action of Tianjin wave, which are 341 mm and 500 mm in the X and Y directions, respectively, and the angles of structure drift ratios are 1/120 and 1/82, respectively. The maximum inter-story drifts appear in the third layer, which are found to be 1/66 and 1/57 in X and Y directions, and can meet the demands of the seismic design code of buildings. The order of yielding for this reinforced concrete frame structure is from the beam-end to the column-end, which achieves the anticipated seismic failure characteristics of “strong column-weak beam” mechanism.
