Stiffness-based optimal design of tall steel frameworks subject to lateral loading
This study presents an effective stiffness-based optimal design technique for planar tall steel building frameworks subject to lateral loading. An initial design under strength constraints is first performed, and then the lateral load resistant system is designed to control any lateral drift of the structure that yet exceeds the drift criteria. The rigid diagphragm effect of the floor slab is accounted for so as to reduce the degreesd of freedom to three at each floor level. Design optimization based on a mathematical programming technique involves minimizing the lateral stiffness of the lateral load resistant system for the structure while satisfying specified drift constraints. Three steel frameworks with diagonal bracing systems are presented to illustrate the features of the design optimization method.
