钢管混凝土在火灾作用下(后)的性能-理论与发展

The performance of concrete-filled stell tubular structures in (after) fire

简要回顾了钢管混凝土火灾中(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,介绍了当今钢管混凝土结构在一些实际工程中的应用和防火措施。最后,对需要进一步开展的研究工作进行了探讨与展望。

The state-in-the-art of fireproofing behaviors of concrete-filled steel tubes under (after) fire is presented generally in this paper.The general response of concrete-filled steel tubular structures in (after) fire is discussed with an emphasis on the composite action between the steel tube and its core concrete.The practice applications and fireproofing measure of concrete-filled steel tubes in some engineering structures are introduced.Finally,the need for further research is discussed.
