Investigation of different infill wall effects on performance of steel frames with shear beam-column connections under progressive collapse

Abstract

This article examined steel frames with shear beam-column connections to determine the effectiveness of different masonry infill walls under progressive collapse. This research concentrated on the shear connection, which is the most common type of steel beam-column connection in steel buildings. Furthermore, this work experimentally evaluated one-third-scale steel-framed configurations with a single shear beam-column connection and another infilled steel frame wall configuration from the literature to verify the validity of 3D finite element models developed using the program ABAQUS. Finite element models were then used to investigate 16 different kinds of steel frames with infill masonry as well as the influence of multiple frames and the number of stories. In addition, the effects of a fully infilled frame and those of a bare frame and an infilled frame with openings were compared in flexural and catenary action phases. Results revealed that the steel building's structural strength and energy dissipation against progressive collapse are significantly improved by infill walls.

Behavior of Steel frame subjected to lateral load

“…It is important to evaluate and strengthen the structural components by various methods as per IS 1893-2002/2016 codes since they provide the guidelines for design and construction of Steel and RCC structures against earthquake forces (5) .Frames were analyzed by response spectrum method to calculate the seismic displacements and stresses (6) .Normally frames are constructed of RCC and steel with suitable infills. These types of frames are increasing the dead load of the structure (7) .Static and dynamic analysis of buildingsgives design parameters such as base shear, story drift and etc (8).…”
