Energy Analysis And Damage Design Of Steel Frame Filled With The Steel Deep Beams

Steel frame filled with the steel deep beams which is the steel deep beam infilled steelframe can achieve the gradual stiffness by changing the plate size. According to the testresults of steel deep beam infilled steel frame structure in the constant axial force andhorizontal low cyclic loading test，we can get the restoring force model by the fitting of theexperimental data and get the results of seismic research by MATLAB programming on theelastic-plastic dynamic time-history analysis method. The main research contents of this paperare as follows：1. We can get the hysteretic energy, damping energy and earthquake input energyincrement expressions of each energy system with single degree of freedom and multipledegree of freedom system by using the method of Wilson-, and gives the system of singledegree of freedom analysis of energy flow diagram.2. We can get hysteretic energy, damping energy dissipation and earthquake input energyto analyze the structure of the lag by the seismic ground motion characteristics (peak ground,spectrum and duration) and the structure dynamic characteristics (natural vibration period anddamping ratio); then on two groups of test specimens in the energy are analyzed; through thestructural dynamic characteristics (natural vibration period and damping ratio) of seismicinput structure self-dissipation effect was analyzed.3. The hysteretic energy provides basis for damage design. According to the steelstructure damage model proposed by Ou Jinping on a steel structure，the deep beams infilledsteel frame structure is damage design.
