Abstract

Direct analysis method is a new approach on stability design of steel structures. This method consider SECOND ORDER EFFECTS by applying lateral force and reducing stiffnesses, however the effective length method consider these effects by increasing column length. The direct analysis method takes the effective length factor unity for all members. Joints displacement, out of straightness and out of plumbness as initial imperfections can be modeled directly or alternatively by applying notional loads in design considerations. Inelasticity and geometric nonlinearities calculated by reducing member stiffness in design considerations. In HEAVY OIL STRUCTURES, significant gravity loads and column length lead to more SECOND ORDER EFFECTS in compare to typical structures. This study evaluates and compares nonlinear dynamic analysis responses of designed HEAVY OIL STRUCTURES in both direct analysis method and effective length method based on ANSI/AISC 360-10 provisions.
