With the increase in heights of mnltistoreyed bnildings and revision of seismic coefficients in the country modal analysis of tall buildings is desirable. This paper presents an efficient method for the dynamic analysis of frames considering effects of bending, axial and shear deformations. The distributed mass of vertical members is replaced by lumps at beam levels. Other assumptions. remain the same as in the case of a static analysis. (Goyal and Sharma, 1968)
