Abstract
Indonesia steel design code 2002 was revised in 2015. The latest version refers to AISC 360-10 which convert steel stability analysis to direct analysis method (DAM). DAM is an elastic analysis which includes second-order effect where P-delta and geometric imperfection are directly calculated during the analysis. Imperfection is modelled as notional load applied horizontally which is determined as 0.002 of gravity load. Numerical study using SAP software had been conducted to compare DAM and the previous method ELM on eccentrically braced frames (EBFs) under seismic load. It is known that EBF is one of earthquake resistant structural systems of steel structure. Numerical study was validated against experimental results performed by other researchers. Similar EBF frames used in the experiment were reanalyzed by ELM and DAM and coefficient of notional load is varied as 0.002 and 0.003. Seismic load applied in the analysis were varied based on three different seismic zones and soil conditions.
