| 摘 要： | 依据15个钢管膨胀混凝土试件的试验情况,研究了钢管膨胀混凝土的水化热,自应力及破坏荷载。确定了膨胀剂的最佳掺量,提出了钢管膨胀混凝土相对普通钢管混凝土的极限破坏荷载的提高幅度,通过算例,验证了非线性有限元分析钢管膨胀混凝土力学性能的方法的正确性。这将有利于指导实际工程的应用。

| Abstract: | According to the test results of 15 specimens of expansive concrete filled steel tube,study the hydration heat,self- stress and the limit bearing capacity of expansive concrete filled steel tube.Determined optimum content of expansive agent.Taking the mothed of expansive concrete filled steel tube analyzed with nonlinear finite element. It is proved by example that the nonlinear finite element analyzed the mechanical properties of expansive concrete filled steel tube.These will do good to the application of... |
