钢结构规范 AISC 360-16 要求将结构体系作为一个整体以及其中的每一个构件进行稳定性考虑。 计算长度法和直接分析法等不同的方法可供选择。 This article will highlight the important requirements from Ch. C and the direct analysis method to be incorporated in a structural steel model along with the application in RFEM 6.
按照 AISI S100-16 对冷弯型钢构件的设计现在可以在 RFEM 6 中使用。 Design can be accessed by selecting “AISC 360” as the standard in the Steel Design add-on. “AISI S100” is then automatically selected for the cold-formed design (Image 01).
在设计冷弯薄壁型钢时经常需要使用特殊截面。 In RFEM 6, the custom section can be created using one of the “Thin-Walled” sections available in the library. For other sections that do not meet any of the 14 available cold-formed shapes, the sections can be created and imported from the standalone program, RSECTION. For general information on AISI steel design in RFEM 6, refer to the Knowledge Base article provided at the end of the page.
对于大跨度的建筑工程,板梁是一种经济的选择。 I-section steel plate girder typically has a deep web to maximize its shear capacity and flange separation, yet thin web to minimize the self-weight. Due to its large height-to-thickness (h/tw) ratio, transverse stiffeners may be required to stiffen the slender web.
