新版《门式刚架轻型房屋钢结构技术规程》在老版规范的基础上对节点设计这一环节做了调整,对节点设计的要求更加严格。在应用新规范进行门式刚架设计时,梁柱节点处常会出现厚度大于100mm的节点板,这在实际施工中显然是不切实际的。本文针对这一问题,以实际工程为例,重点介绍新规范规定下节点设计需要注意的几个问题。
The new version of “technical specifications for steel structure of light-weight portal frame” made adjustments to the node design on the basis of the old version of the norms, the requirements of the node design more stringent. In the application of the new code for the design of portal frame, the node of beam and column often appear more than 100mm thick nodal plate, which is obviously impractical in the actual construction. This article addresses this issue, taking practical engineering as an example, focusing on several issues that need to be noticed in the node design under the new rules and regulations.
