WebSep 21, 2024 · Partially restrained (PR) bolted T-stub connections have been widely used in replacement of established fully restrained (FR) welded connections, which are susceptible to sudden brittle failure. These bolted T-stub connections can permit deformation, easily exceeding the allowable limit without any fracture because they are constructed with a … A comparison between results from the component-based finite element method (CBFEM)and traditional calculation methods used in US practice for T-stub connections is presented in this study. A schematic of the connection investigated is presented in Fig. 1. The limit states evaluated are slip, bolt tension … See more The first limit state investigated is slip. The configuration of this example matches that of Example J.5 of the AISC Design Examples … See more Prying action impacts the evaluation of plate bending strength and bolt strength. Part 9 of the AISC Manual (2024) presents equations that account for prying action. The equations are … See more The third investigation examines the strength of the beam flange and bolts. The beam flange was varied by selecting different beam sections. Six beam sections were selected for investigation as listed in Tab. 1. To … See more The second investigation examines the strength of the T-stub and bolts. Same as the previous investigation, the bolts are Group A (e.g. A325) … See more

WebThe connection of the stub to the rest of the beam is normally made with a bolted cover plate splice. Note that the bolted splices should use preloaded bolt assemblies if slip in the connection is to be avoided. A typical arrangement for … WebJul 1, 2015 · T-stub component is the most important component of connection in a steel-frame structure because it plays a major role in determining the overall strength, stiffness and ductility of a connection ...
