The Direct Analysis Method: Bridging the Gap from Linear Elastic Analysis to Advanced Analysis in Steel Frame Design

Developments in analytical software and computer hardware over the past few decades provide engineers with powerful tools for more realistically considering the behavior of steel structures. More sophisticated methods of analysis offer significant advantages in steel frame design by eliminating the need to calculate effective length factors and more directly including factors that affect system and member strength. One such method, the Direct Analysis approach, accounts for the effects of member inelasticity and frame imperfections in the assessment of both member and system strength. The latter is achieved by directly including these effects in calculating the distribution of forces in the structural system. This approach is applicable for use in the design office using commercially available software and it is applicable to a wide variety of structural problems including braced frames, moment frames and mixed systems. Just as importantly, the approach it allows for a natural transition between current elastic analysis procedures and the future availability of second-order inelastic analysis programs suitable for use with an advanced analysis-design approach.
