摘要
为建立FRP-混凝土-钢双壁空心管(简称双壁空心管)截面轴力-弯矩相关曲线方程,推导了双壁空心管压弯构件截面承载力计算公式,计算结果与试验结果符合较好。对构件的纤维特征值、内层钢管强度和含钢率等因素对双壁空心管截面轴力-弯矩关系的影响进行了分析。基于理论分析和试验结果,提出了双壁空心管截面轴力-弯矩相关曲线方程。
In order to develop the axial force-moment （N-M） interaction relationship of FRP-concrete-steel double-skin tubes （DSTs）, formulas of calculating strength of DSTs under compressive force and moment are derived. The calculated results agree well with the test results. Influences of fiber characteristic value, steel tube strength and steel ratio on the axial force-moment interaction relationship of DSTs are investigated. Based on the theoretical analysis and test results, the N-M interaction relationship equations of DSTs are developed.
