The standing seam roof (SSR) system is the most commonly used roof system for metal buildings due to its superior durability, water tightness, and energy efficiency. In this type of system, SSR panels attach to Z-shaped or C-shaped purlins with clips, and the purlins are in turn connected to rafters (i.e. roof beams). For the design of metal building rafters against lateral torsional buckling, bottom flange braces provide torsional bracing to the rafter and the SSR system provides some lateral bracing. However, the degree to which the SSR system can restrain the rafter against lateral movement has not previously been …
Influence Of Bracing On Buckling Strength Of Pultruded Glass Fiber Reinforced Polymer Frames, Mojtaba B. Sirjani, Zia Razzaq
Influence Of Bracing On Buckling Strength Of Pultruded Glass Fiber Reinforced Polymer Frames, Mojtaba B. Sirjani, Zia Razzaq
Civil & Environmental Engineering Faculty Publications
A numerical study of the influence of structural bracing on the buckling strength of pultruded Glass Fiber Reinforced Polymer (GFRP) frames is presented. Although the influence of bracing on frames made from other materials such as steel have been studied in the past, this paper investigates the performance of pultruded GFRP portal frames with pinned or fixed column bases. Each frame is constructed with pultruded GFRP I-section members. The influence of I-section column major and minor axis orientation is also investigated. The results demonstrate the practical significance of bracing pultruded GFRP frames. The results show that the buckling loads for …
Lateral-Torsional Buckling Strength Of Two-Span Glass Fiber Reinforced Polymer Beams, Mojtaba B. Sirjani, Zia Razzaq
Lateral-Torsional Buckling Strength Of Two-Span Glass Fiber Reinforced Polymer Beams, Mojtaba B. Sirjani, Zia Razzaq
Civil & Environmental Engineering Faculty Publications
This paper presents the outcome of a study of two-span glass fiber reinforced polymer (GFRP) I-section beams susceptible to lateral-torsional buckling when subjected to gradually increasing concentrated vertical load(s) in the presence of two different types of lateral bracing schemes. It is found that loading one span results in a smaller buckling load as compared with the cases with loading in both spans regardless of the type of bracing scheme used. Also, the study shows that the addition of midspan braces for the GFRP beams results in up to 5.5 times increase in the buckling load capacity.
