Description The fundamental periods of buildings are essential to calculate the design base shear and lateral force under seismic actions. Most seismic codes specify empirical formulae to estimate the fundamental vibration period of buildings. These empirical formulae are used for both low- and medium- rise buildings. These formulae depend on the building materials (steel, reinforced concrete etc), building types (frame, shear wall etc) and overall dimensions of the buildings. In this paper, for finding the fundamental natural period of steel moment resisting frames, numerical studies are carried out, and by regression analysis, empirical formulae are derived for low- and medium- rise buildings. The numerical studies carried includes, the influence of the plan and bay dimensions, normalized stiffness and height of storeys on fundamental frequency of the moment resisting frames.
