摘　　要：配T形钢的型钢混凝土异型柱,由T形钢桁架及部分纵向钢筋、箍筋和混凝土组成,具有承载能力高、抗震性能好、施工方便等优点。通过该种异型柱的具体配钢方式及施工工艺,提供了截面型钢的混凝土保护层厚度计算公式,正截面承载能力计算的办法及编制计算机程序的技巧,斜截面承载能力计算公式及方法,计算结果与试验结果吻合较好,研究结果可供工程设计及施工参考。A new type of structure component is introduced, which is T-shape steel truss reinforced concrete special-shaped columns. This component composed by T-shaped steel truss and vertical steel bars, stirrups and concrete. Which have the following advantage, strong bearing capacity, high seismic performance and construction convenient. This new type of componenVs steel layout fashion and construction technology, the calculation formula about minimum thickness of concrete, the bearing capacity of normal section calculation method and computer program skills, and formulas about ultimate shear bearing capacity are given, the calculating results are in good agreement with test. All of this may be help for engineering design and construction.
