【摘要】 把钢管混凝土当作一种组合材料，对钢管混凝土柱的组合截面抗弯刚度进行了理论上和试验上的研究，并与原截面尺寸计算得到的刚度值进行了比较，在此基础上对钢管混凝土高层框架结构进行了初步分析。更多还原

【Abstract】 In this paper,besed on considering the CFST as a composite material,it is the first time to theoretically analyze the CFST composite sectional bending rigidity and compare with the rigidity devived from the oringinal section dimension Using the results,this paper analyzes the high-rise frame structure of CFST preliminarily更多还原
