Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...

This paper is concerned with the determination of optimal sensor locations for structural modal identification in a strap-braced cold formed steel frame based on an improved genetic algorithm (IGA). Six different optimal sensor placement performance indices have been taken as the fitness functions two based on modal assurance criterion (MAC), two based on maximization of the determinant of a Fi...

The paper describes a project which uses a novel non-linear computational method to teach structural topics ranging from elementary statics to plastic analysis of beams, and frame buckling. The project centers around a computer program, called Arcade, developed using a computational method, called a physics engine, which has been widely used in computer games. This method has two special charac...

This paper describes the design, testing, and finite element modeling, of a proofof-concept eccentrically braced frame specimen utilizing a hybrid rectangular shear link. The link is self-stabilizing and does not require lateral bracing, making it suitable for use in steel bridge piers where lateral bracing can be difficult to provide (building applications are possible as well). Equations used...

Background: The seismic retrofitting of frame structures using hysteretic dampers is a very effective strategy to mitigate earthquake-induced risks. However, its application in current practice rather limited since simple and efficient design methods are still lacking, the more accurate time-history analysis time-consuming computationally demanding. Aims: This paper develops applies retrofit me...
