The catastrophic events of September 11, 2001, stand out as a major motivation for research on improving the understanding structural behaviour in fire. These included first complete collapse tall steel framed structure solely due to World Trade Center 7 (WTC7) was 47-storey office building within WTC complex that collapsed fire initiated by debris from WTC1. In following years, detailed invest...

Since the tragic event of World Trade Centre (WTC), efforts to understand realistic fire behaviour in tall buildings are accelerated. It is critical dynamics involved a compartment before performing forensic investigation accident. In this paper, various scenarios considered simulate high-rise building and demonstrated case Plasco Building using computationally fluid (CFD). Two fuel distributio...

Abstract This study presents the impact of near-field and far-field earthquakes on seismic design Intermediate Moment Resisting Frame (IMRF) Special (SMRF) structures through FEMA (Federal Emergency Management Agency) P695 methodology to highlight importance probabilistic collapse as well performance factors these structures. The purpose this is investigate steel intermediate special moment res...

Abstract Buckling restrained braces (BRBs) represent an effective strategy for the seismic retrofit of existing steel moment resisting frames (MRFs), as they contribute to increasing strength and ductility capacity structure. However, current design strategies do not provide recommendations on how performance increase is achieved. Prioritising either or has impact damage evolution affects overa...

Conventional fiber-reinforced polymers (FRPs) have a relatively linear stress–strain behavior up to the failure point. Therefore, they show brittle until Shape memory alloys, in addition having high ductility and good energy dissipation capability, are highly resistant corrosion performance against fatigue. using SMA fibers production of FRPs can be suitable solution solve problem conventional ...

Propagation of seismic waves through soil deposits may considerably alter theircharacteristics at surface. This ultimately influences the performance structures.The are included in codes (e.g. Eurocode 8, EC8) by meansof proposed design response spectra for different classes used or retrofittingof structures. Nevertheless, a smooth spectrum cannot always representspectral an actual input motion...

Masonry infill walls are among the most vulnerable components of reinforced concrete (RC) frame structures. Recently, some techniques for enhancing performance infills have been proposed, aiming at improving both global and local behaviour infilled structure. Among promising ones, there those that aim to decouple or reduce infill-frame interaction by means flexible sliding joints, relying respe...

Abstract Nowadays, retrofitting-damaged buildings is an important challenge for engineers. Finding the optimal placement of Viscous Dampers (VDs) between adjacent structures prone to earthquake-induced pounding can help designers implement VDs with optimizing cost construction and achieving higher performance levels both structures. In this research, linear nonlinear 3-story, 5-story, 9-story S...
