［摘要］鋼管混凝土疊合柱具有抗震性能好、斷面小、防火防腐性能好等眾多優(yōu)點，但是在目前的結構設計軟件中很難真正模擬，相關規(guī)范也只給出了簡化計算方法，并且計算過程仍非常繁瑣。從材料本構關系出發(fā)，提出了基于平截面假定的疊合柱正截面受壓承載力計算方法，并進行編程計算，計算結果表明此計算方法很好地反映了疊合柱分階段受力的特點。此計算方法已在一些項目的設計中得到運用，效果較好。
［關鍵詞］鋼管混凝土疊合柱； 受壓承載力； 計算方法

Abstract:Steel tube-reinforced concrete column has many advantages such as good seismic performance, small section, good fire and corrosion resistance, but it is difficult to simulate in the current structural design software. The relevant specifications only give a simplified calculation method, and the calculation process is still very cumbersome. Based on the constitutive relation of materials, the calculation method of the compressive bearing capacity of the steel tube-reinforced concrete column based on the assumption of plane section was proposed and programming calculation was carried out. The calculation results reflect the force characteristics in different stages of the columns well. This calculation method has been applied in the design of some projects and has a good effect.
Keywords:steel tube-reinforced concrete column; compressive capacity; calculation method
