Application of multi-spring element model in space steel frame

WANG Kaiqiang,SUN Feifei,HU Dazhu(College of Civil Engineering,Tongji University,Shanghai 200092,China)  
Multi-spring element model is effective in simulating the combined action of axial force,moment and shear force as well as reflecting the hysteretic behavior under the reciprocal load or earthquake load.The theory about establishing element matrix with multi-spring model is introduced.The key formulas and element matrix is also provided.Compare the results of nonlinear subprogram of MTS steel structure design program which is mainly compiled with multi-spring element model and experiment or SAP2000.The correct of this model and the reliability of MTS program are verified by the comparison.
