Performance of Rigid Steel Frames under Adequate Soil Conditions Using Seismic Code Provisions

Abstract

This study is focused on nonlinear analysis and design of spatial and perime-ter moment resisting frames for a 9-storeys office building having 9.15 m span. Seismic design criteria of Eurocode 8 Ductility Class High (DCH) with behavior factor (q) of 6.5 and AISC/ASCE code, Special Moment resisting Frame (SMF) with response modification factor (R) of 8 were employed. The design outcomes are expressed in terms of frame performance (non-linear analysis), section profiles (code recommendations), strength-demand to ca-pacity ratios, drift-demand to capacity ratios and structural weight. The con-sequences of the research compare two codes in term of weights and design performances. This will aid professional engineers and researchers to select effective design criteria and capacity design rules efficiently.
