To make a top local adding stories of “L” flat facade irregular frame structure with good resistance to twist and integrity, can better satisfy the requirements of local seismic fortification intensity,using metal damper to this after-adding-stories framework model for processing. Using SAP2000 finite element analysis software modeling and in its install metal damper dynamic time-history analysis before and after. Results show that the structure using metal consumption technology in consume earthquake input energy at the same time can enhance structure rigid and floor wrest resistant and strengthen the lateral stiffness integral structure seismic performance.

The introduction of can reasonable description of transversely isotropic soil micro-element strength parameters - damage variable, according Mohr-Coulomb strength theory and soil micro-element theory of geotechnical failure to obey normal distribution characteristic,the damage variables can true reflection of transversely isotropic soil softening characteristics.Based on the uniaxial stress-strain curve of the geotechnical rupture process of statistical damage constitutive model of geotechnical, statistical damage variable is adjusted, establishing the reflect the complete process of geotechnical failure of 3D statistical damage constitutive model.Model is simple, easy to use, can better reflect the actual.The model reflects the failure process of geotechnical damage not only with geotechnical micro-unit strength changes, and the effect of geotechnical stress state.
