Numerical investigation of the behaviour of bolted and welded top and seat angle connection in progressive collapse of steel structures [PDF]
Journal of Structural and Construction Engineering, 2019 After failure of a column in structure by an abnormal loading, undesirable performance and damage of connections of the beams connected to the top of this column, can lead to the local failure of floor and in turn result in progressive collapse in the ...

Research on Initial Stiffness of Top-and-Seat Angle Semirigid Connections [PDF]
Proceedings of the 10th Pacific Structural Steel Conference (PSSC 2013), 2015 Based on the mechanical characteristics, deformation characteristics of top-and-seat angle semirigid connections, the initial stiffness of the connections were studied. The initial stiffness were derived theoretically with component method. Analytical formulas and fitted formulas were obtained, and these formulas were analysed comparatively with test ...

Nonlinear Analysis on Prying of Top-and Seat-Angle Connections
Journal of applied mechanics, 2001 application/pdf Nonlinear finite element (FE) analyses are performed to simulate the behavior of top- and seat-angle connections. Contact model with small sliding option is applied between contact pair surfaces of all connecting elements. Bolt pretension force is introduced in the initial steps of analysis.

Numerical Investigation of the Behavior of Unstiffened Semi-Rigid Top and Seat Angle Connections under Monotonic Loading [PDF]
Buildings, 2023 In steel structures, unstiffened top and seat angle connections (TSACs) show semi-rigid behavior and transfer both the vertical reaction and some end moment of the beam while also making some degree of rotation.

Moment Rotation behavior of Top and Seat Angle Connection with Angle Stiffeners
ASPS Conference Proceedings, 2022 The design specifications for seven commonly used semi-rigid steel connections have been embodied in Indian Standard Code of Practice for General Construction in Steel (IS800:2007). Bolted connections are proved to be efficient by several researchers for its energy dissipating capability under reversal of loading; among them top and seat angle (TSA ...

Design Tables for Top- and Seat-Angle with Double Web-Angle Connections
Engineering Journal, 1998 This paper provides a set of design tables, based on the AISC/LRFD Specification (1994), for the selection of top and seat-angle with double web-angle connections given beam sections and applied loads. These tables enable the engineer to rapidly select proper angle sizes and configurations as well as determine the moment-rotation curve for the ...
