A New Calculation Approach on Fundamental Nutural Period of Vieration for Semirigid Steel Structure
The new calculation method of fundamental natural period of vibration for multistory and high-rise steel structure, in which semirigidity of joints between beam and column, shear deformation for the cross section and so on is considered at the same time, is presented in the paper. The lateral drift stiffness of column in steel structure and inter-story stiffness of steel structure, which joints semirigidity, shear deformation and effects for steel structure is simultaneously considered, is derived in the paper. General expression for stability function considered shear deformation of the cross section for beam-column members is put forward.The approach is relatively simple and more practical. It can be referred to steel structural design.
