【摘要】 简要回顾了钢管混凝土火灾后力学性能的研究现状,探讨了组成钢管混凝土的钢管及其核心混凝土之间在火灾中(后)的相互作用问题,提出了基于神经网络的高温后钢管混凝土柱残余力学性能的评定方法,并与其他方法进行了比较.最后,对今后进一步开展的研究工作进行了展望.更多还原

【Abstract】 The state-of-the-art of the behavior of concrete-filled steel tubes on (after) fire is briefly reviewed and the interaction of the two kinds of material is discussed in this presentation.Then an assessment methods based on neural networks to predict the residual strength of concrete-filled tube after fire is presented,and the comparison of the methods with other calculation methods is carried out.Finally,the further research is pros- pected.更多还原
