Nonlinear Analysis of Steel Structure Bent Frame Column Bearing Transverse Concentrated Force at the Top in Factory Buildings

Abstract

The steel bent frame structure of single-story factory buildings is actually a spatial structure system. Different bent frame columns are connected with the roof of bent frame structure, making the columns work and bearing the load together. In the steel frame of the factory building with bridge cranes below 20 t, variable-section columns with corbels are used to bear the crane load. In this article, the steel bent frame column of single-story factory buildings was taken as the research object. The bent frame column was simplified as a cantilever variable stepped column bearing a transverse concentrated force at the top. After simplifying the model, the theoretical formula of deflection, rotating angle, and bending moment of the compression rod was put forward. Moreover, bending deformation and stability of variable stepped columns were analyzed in order to obtain the theoretical and practical formula, then the ANSYS software was used to simulate the bent column.

Analysis of the First Metallic Works That Represented a Geometric Innovation in Their Architectural Application: The Origin of the Architecture-Engineering Dichotomy

“…In relations between engineer and architect [17], France has always been a pioneering country, and not in vain, for one of the first buildings in which an architect and an engineer worked together, but with different skills and different responsibilities, was in the dome of the La Halle aux Blés in Paris in 1811 (Figure 8), where the old structure of timber from the market that covered the circular courtyard was destroyed by fire in 1802. In 1811, the architect Bélanger [A6] [18,19], together with the engineer Brunet, built an adaptation of the old methods to the new material, replacing the wooden beams with a structure made of iron and copper ribs [20].

Modeling of Curvilinear Steel Rod Structures Based on Minimal Surfaces

“…It encompasses the application of mesh generation by dividing a complex problem into small ones, as well as using software that is coded with an FEM algorithm. It allows one to model, analyze and design structures of various materials, e.g., the steel structures, among others [29][30][31][32][33].…”

Experimental and Finite Element Study of Polymer Infilled Tube-in-Tube Buckling Restrained Brace

“…The test program investigated the buckling behavior and unconstrained length stiffener detail of the BRB. Nonlinear finite element analysis [21][22][23] was conducted to better understand the proposed BRB.…”
