摘要
通过10根钢管混凝土叠合构件的受弯试验,研究了其抗弯性能;分别用极限平衡法和条带法计算了试件的受弯承载力,用条带法计算了试件截面的弯矩-曲率全曲线,计算结果与试验结果符合;根据试验结果,钢管混凝土叠合构件截面的弯矩-曲率关系曲线可简化为三折线,并给出了用弯曲刚度表示的三折线的方程。
Flexural behavior of the steel tube reinforced concrete member was studied by bending test of lO specimens. The bending strength of specimens was calculated by ultimate balance method and strap method respectively. The complete moment-curvature relationship curves of specimens were calculated by strap method. The analytical resuhs had good agreement with the test resuhs. Based on the test resuhs the moment-curvature relationship curve of steel tube reinforced concrete member can be simplified as a tri-linear model. Equations of the model expressed with bending stiffness were proposed.
