Seismic loads for high rise buildings are affected by higher modes even base shear force. This paper investigates the base shear coefficient for the preliminary earthquake resistant design considering the second mode contribution using a simple model and the design earthquake acceleration response spectrum. The required design base shear strength is established from this spectrum and the design criteria such as story drift limitation and allowable ductility factors of structural members. Final suggestion of this paper is C_B=0.24/Ti, where C_B is base shear coefficient and Ti is initial period of a building. The dynamic response analysis for the buildings having the base shear strength calculated by this equation showed sufficient earthquake resistant ability.
