Collapse simulations of steel buildings under fire
Collapse analysis of steel structures under extreme hazards has been placed on the forefront of research in recent decades. This was primarily motivated by the September 11, 2001, terrorist attacks, which caused the complete collapse of the World Trade Centers (WTCs) including WTC-7. The collapse, …

Performance-Based Analysis of Steel Buildings: Special Concentric Braced Frame
The performance-based analysis methods and evaluation criteria in ASCE 41-06 were used to evaluate a special concentric braced frame building based on the design standards in ASCE 7-05. A rectangular, six-story office building was evaluated using linear static, linear dynamic, nonlinear static, and …

Computational and Experimental Study on the Behavior of Diaphragms in Steel Buildings
The lateral force resisting system (LFRS) of a steel building consist of two parts, i.e., a vertical LFRS such as braced frames or shear walls, and a horizontal LFRS with diaphragms playing a crucial role. There are various types of floor and roof diaphragms in steel buildings, such as …

Evaluation of Connection Fracture and Hysteresis Type on the Seismic Response of Steel Buildings
… the maximum displacement response amplitude of buildings plays a important role in determining the design forces. Linear, bilinear, strength degradation, stiffness degradation, and connection fracture models were used to determine the effects of hysteresis type on multi-degree-of-freedom (MDOF) …

Column Capacity Evaluation For Low-Rise Moment Frame Steel Buildings In Mississippi Subject To Wind And Seismic Hazards
For the design of steel frame structures, AISC outlines approaches of second-order analysis. In this study, two of these approaches are considered: Amplified First-Order Analysis Method and Direct Analysis Method. The methods were studied using SAP2000. Amplification of moments in a two-story plane …

Reliability based criteria for cold-formed steel members
<p>"In the design of steel buildings, the "Allowable Stress Design (ASD)" method has long been used for cold-formed steel structural members in the United States and other countries. In this approach, member forces, or moments, determined on the basis of working loads should not exceed the …

Effect of seismic loading on steel moment resisting frames
In recent history, the use of Steel Moment Resisting Frames (SMRF) in many structural steel buildings has become popular among many engineers and designers. The use of these moment resisting frames allows for more open spaces between floors and columns than in buildings that use the more …

Effect of Continuity Plate Eccentricity on the Performance of Welded Beam-to-Column Connections
<p>Beam-to-column connections in structural steel buildings may have varying degrees of rotational restraint and varying degrees of moment transfer. In fully restrained moment connections, shear is typically transferred through the beam web, while the moment is mostly transferred through the beam …
