Modular systems have been mostly researched in relatively low-rise structures but, lately, their applications to mid- to high-rise structures began to be reviewed, and research interest in new modularization subjects has increased. The application of modular systems to mid- to high-rise structures requires the structural stability of the frame and connections that consist of units, and the eval...

Steel Plate Shear Walls (SPSW) consist of unstiffened infill steel panels surrounded by columns, called Vertical Boundary Elements (VBE), on both sides, and beams, called Horizontal Boundary Elements (HBE), above and below. These infill steel panels are allowed to buckle in shear and subsequently form a diagonal tension field. SPSW are progressively being used as the primary lateral force resis...

Current seismic design philosophy is based on dissipative structural response, which implicitly accepts damage to the main structure and significant economic losses. Repair of the structure is often impeded by the permanent (residual) drifts of the structure. The proposed research aims at reducing the repair costs and downtime of a structure hit by an earthquake, and consequently more rational ...

A simplified fragility analysis of steel building frame is presented which can be used for preliminary estimate of its probability of failure. The risk analysis procedure uses the format of probabilistic Risk Analysis (PRA) and considers band limited white noise at the bed rock as the seismic input. The steel building frame is modeled as a 2D frame and Pushover analysis is then carried out to o...

This research suggests a novel method to use steel cables as a structural bracing system. The Moment Resisting Frame (MRF) works in tandem with the cable bracings when this method is used. The suggested bracing model can address the fundamental problem of current cable bracing methods, namely the lack of flexibility while keeping costs to a minimum. This approach requires no additional equipmen...
