Automated performance-based design of steel frames
Abstract
This paper presents an automated performance-based design methodology of steel moment frames using the reliability methods of FEMA 350 (FEMA, 2002, and Foley et al, 2003.) An integrated and flexible computational platform is programmed using Carroll's GA (Carroll) and DRAIN-2DX (Powell et al, 1993). It is validated through designing different structural systems for a variety of design optimization objectives. The present paper illustrates the process and discusses the resulting designs of a portal frame subjected to multi-level earthquake scenarios. The automated probabilistic performance-based design (PBD) is implemented using inelastic response history analysis to account for geometric and material non-linearities. The design objective is to minimize the cost of construction constrained by a certain predefined set of confidence levels in meeting multiple structural performance-objectives for multi-level seismic hazard.
