By means of calculating example, shear deformation of joint and second order effect which affect mechanical performance of structure ,seismic design and dynamical reliability of steel frame are investigated in this paper.

During the dynamic interaction of pile-soil-superstructure,it can not be neglected for the influences of seismic response upon the internal force and displacement of high rise steel frame structure due to both second order effect and joint shear deformation.

Based on the second\|order analysis of the beam element with semi\|rigid regions at ends,a new method of the free vibration analysis of steel frame structures is developed,which accounts for the second\|order effect and the joint shear deformation.

Mechanisms of localized shear deformation and fracture in amorphous alloys are summarized based on free volume model,adiabatic shear model,dislocation model and mechanics model.
