阐述了钢结构中节点在常温下和在高温下的行为和设计方面存在的差异,指出采用在常温下的设计方法应用于火灾设计时不合理的地方,并提出在高温下的设计中应该综合考虑节点的牢固性。接着,该文介绍了一组旨在研究常用的节点在高温下的牢固性的试验,并对试验的主要观察现象和结论做了报告。最后,针对性能化设计体系,总结了节点设计中的3个要素,即节点的抗弯能力、抗轴拉/压能力和塑性转动能力之间的关系,并提出了在高温下对节点进行性能化分析和设计的方法。
The differences of the behavior and design of joints in steel structure at normal temperature and at high temperature are described. It is pointed out that the design method applied at room temperature should be used in the unreasonable design of fire, and the design should be integrated at high temperature Consider the firmness of the node. Next, the paper presents a set of experiments designed to study the robustness of commonly used nodes at high temperatures and reports the main observations and conclusions of the experiment. Finally, for the performance-based design system, the three elements in the node design are summarized, that is, the relationship between the bending resistance, anti-axial pull / pressure capability and plastic rotation capacity of the node. The performance of the node at high temperature Methods of analysis and design.
