| 摘 要： | 进行了钢管混凝土哑铃型梁的试验与分析.哑铃型截面包含腹腔内填有混凝土的传统形式和腹腔内不填混凝土的新型截面.试验结果表明,钢管混凝土哑铃型梁具有良好的弹塑性和延性,构件挠度达跨径的1/20时仍能继续承载.腹腔内的混凝土对腹板的受力性能有一定的影响,但对梁的总体受力性能影响不大.

| Abstract: | Bending of concrete filled steel tubular (CFST) dumbbell-shaped beams is studied experimentally. Two types of cross sections of beams are discussed. One is the traditional type with concrete-filled in the web space, the other is a new type without concrete in it. Experimental results show that the CFST dumbbell-shaped beam has favorable elastoplastic and ductile properties. It can bear load even when the deflection reaches one-twentieth of its span. The concrete in the steel web has some influence on the local behavior of the web, but has very small influence on the overall behavior of the beam. |
