Limit State Response of Composite Columns and Beam-Columns Part II: Application of Design Provisions for the 2005 AISC Specification

摘要

The strength of composite beam-columns, including steel sections encased in concrete (also known as SRC) and steel sections filled with concrete (CFT), as presented in the 2005 AISC Specification for Structural Steel Buildings, ANSI/AISC 360-05 (AISC, 2005a), hereafter referred to as the 2005 AISC Specification, must be computed based on first principles of mechanics and reasonable models for the stress-strain characteristics of the materials. Chapter I of the 2005 AISC Specification provides two options to fulfill this requirement: a general approach labeled the strain-compatibility method and a simplified approach labeled the plastic stress distribution method.
