Dynamic elastic-plastic analysis of a structure generally can be divided into following steps: (1) According to the mechanics characteristics of a structure system, establish a reasonable structural vibration model; (2) According to the material properties, structure type and loading condition, choose proper structural restoring force model, and determine restoring force characteristic parameters of feature points and the restoring force characteristic curves of each line segment stiffness value corresponding to cracking, yielding and ultimate displacement (3) Establish vibration differential equations of the structure under dynamic loads; (4)By step-by-step integration method, solve the vibration equations and get the responses of displacement, velocity and acceleration, and the whole process of structural seismic; (5) Draft angles are calculated and checked if they are less than allowable values.

The heat conduction equation is: (1) The boundary condition is: (2) All above, ρ is Material density (kg/m3);c is Material specific heat capacity (J / (°C · kg)); t is time(s); T is the temperature at the point (X,Y,Z);k is the thermal conductivity of the material (W / (m · ° C));Tf is Flame temperature (° C), it can be measured by furnace temperature curve; h is Convective heat transfer coefficient (W / (m2 · ° C)), to fiber burning fire , It’s usually set 25.To hydrocarbon burning fire, it’s usually set 50. is shape factor, generally take 1.0.is comprehensive radiation coefficient (W / (m2 · ° C)), For fire surface it’s generally take 0.5.
The coefficient of thermal conductivity and specific heat of steel or concrete, etc; with the elevated temperatures and the different material components were changing.
Researchers proposed numerous calculated methods about steel and concrete materials, thermal performance parameters, countries of fire resistant design specification is also not the same as the value of the steel and concrete thermal parameters.
