INELASTIC FRAME ANALYSIS USING A CONTINUUM MODEL. IN: STRUCTURAL STABILITY RESEARCH COUNCIL. 1990 ANNUAL TECHNICAL SESSION, STABILITY OF BRIDGES, ST. LOUIS, MISSOURI, APRIL 10-11, 1990

The United States is moving towards the universal adoption of the Load and Resistance Factor Design (LRFD) method for steel structures. Unlike current allowable stress design, this method is based on ultimate strength principles. Checking the stability of structures subjected to factored gravity and lateral loads requires the use of a frame analyses which include both material and geometric nonlinearities. Utilizing such analyses to compute ultimate load carrying capacities of steel frames has been widely studied. Discrete finite element techniques including nonlinear geometric effects and inelastic material models have been developed. However, these methods normally require a large computational effort. This paper describes how the use of continuum modeling can lead to a computationally efficient inelastic frame analysis technique.
