Damage Theory and Finite Element Model of Neoteric Protect Buildings/Li Ruili,Cao Zhiyuan(Mechanc Engineering and Technology, Tongji Univ.,Shanghai 200092,China)
Abstract:The damage theory and FEM model of the neoteric protect buildings are presented  according to the principle of damage theory.The constitutive model that contains the damage parameter and the expressions of reanalysis is built.It has important value in the analysis and evaluation of the neoteric protection buildings.
