OBJECTIVE/SCOPE To introduce composite columns; 组合柱概念、分 类、构造 To describe their behavior; 组合柱的特性 To explain the design method for axially loaded composite columns. 组合柱承载力计算、设计
7.1 Introduction By definition,columns are structural members which are subjected mainly to axial forces and very little transverse shear. Composite action in columns utilizes the favorable tensile and compressive characteristics of the steel and concrete,respectively.Complete interaction between the structural components of the column,the steel and concrete elements,is achieved through direct interface bond. Two basic types of composite columns are used in buildings:encased composite columns型钢混凝士柱 and concrete filled composite columns钢管混凝土柱

Uses for Composite Columns Extra capacity in concrete column for no increase in dimension Large unbraced lengths in tall open spaces -Lower story in high rise buildings -Airport terminals,convention centers Corrosion,fireproof protection in steel buildings Composite frame-high rise construction Transition column between steel,concrete systems Toughness,redundancy as for blast,impact
Uses for Composite Columns • Extra capacity in concrete column for no increase in dimension • Large unbraced lengths in tall open spaces – Lower story in high rise buildings – Airport terminals, convention centers • Corrosion, fireproof protection in steel buildings • Composite frame – high rise construction • Transition column between steel, concrete systems • Toughness, redundancy as for blast, impact
Applications around the world Full-scale 3stor.3-bay braced frame tested in Taiwan
