| Abstract: | The rotational restraint stiffness of beams and columns in frame structure is a very important parameter.In calculating the frame member's fire resistance and anti fire design,this parameter is of vital importance.This paper used the FEM to calculate the rotational restraint stiffness of every beam and column in a typical 4 bay 6 story frames,and analyzed the factors that influence this parameter. |
