[Abstract]:Absrtact: the research on seismic behavior of steel-concrete composite frame structures at home and abroad mainly consists of pseudo-dynamic test method in simple frame form and finite element analysis of bar system, and the application of three-dimensional finite-shell solid finite element analysis method is relatively rare. In this paper, the seismic behavior of multi-story steel-concrete composite frame structure is analyzed by using Abaqus finite element analysis software. The main research contents are as follows: (1) the basic analysis method of Abaqus is introduced, and based on the plastic damage constitutive relation of concrete proposed by our group, The constitutive relation of elastoplastic hardening monotone loading and mixed reinforced cyclic loading is introduced. The modeling method and modal analysis method of steel-concrete composite frame are introduced, and its natural vibration performance is analyzed. From the static point of view, the finite element analysis and experimental verification of octagonal concrete filled steel tubular short columns are carried out by Abaqus software, and the bearing capacity formula of octagonal concrete filled steel tubular short columns is put forward. From the point of view of quasi-static force, using Abaqus finite element software, the concrete filled circular steel tube column, square steel tube concrete column and steel-concrete composite beam are studied. The hysteretic behavior of circular concrete-filled steel tubular column-steel beam composite joints and circular concrete-filled steel tubular column-steel beam composite frames are analyzed and tested. By using Abaqus finite element software, the elastoplastic seismic response analysis and comparison of the experimental results of the existing steel-concrete composite frame model are carried out. (3) A reasonable constitutive relation between concrete and steel is adopted. Using Abaqus finite element software, the 3D fine finite element solid model of 3 脳 3 脳 3 span 10 story steel-concrete composite frame is established. The elastic-plastic time-history response and displacement time-history response of the frame structure under the action of seismic waves under eight conditions are analyzed. The stress time history response of steel tube, core concrete, steel beam and bolt in every key position is discussed. The interaction between steel tube and concrete and the energy dissipation of bolt in the steel-concrete composite frame structure under earthquake are discussed. The results show that the frame structure has good dynamic performance under seismic waves.
