THE SUBASSEMBLAGE METHOD OF DESIGNING UNBRACED MULTI-STORY FRAMES,
Abstract
A new method is presented for the design of columns and girders in unbraced multi-story steel frames which are subjected to combined horizontal wind loads and distributed gravity loads. The method is based on the concept of sway subassemblages and considers the elasticplastic behavior of girders, the instability of the beam-columns, and second order effects (caused by P-delta moment) on the structure. It employs a semi-graphical solution using specially prepared charts to develop the complete horizontal load-deflection relationship for each story designed. A design procedure is proposed, and an illustrative example is included to demonstrate the technique developed. (Author)
