The braced tube frame system, a combination of perimeter frame and bracing frame, is one
of the systems used in tall buildings. Due to the implementation of this system in tall …

Steel bracing systems can be used effectively for seismic retrofitting of existing RC buildings
as well as for seismic design of new buildings. Although adaptation of bracing to upgrade …

Slit dampers are a specific type of metallic yielding dampers, for which many studies have
been conducted in recent years, to investigate their behavior and possible applications in …

In this paper, overstrength, ductility and response modification factor of buckling restrained
braced frames (BRBF) dual system were evaluated. To do so, building with various stories …

Recent earthquakes in Turkey (1999), Taiwan (1999) and Algeria (2003) demonstrated the
catastrophic impact of such power upon urban cities. A great number of existing buildings in …

This study aimed to compare the seismic behaviour of different bracing systems in high rise
2-D steel buildings. Nonlinear static pushover analyses were carried out to assess the …

The energy dissipation capacity of conventional concentric braced frames in multi-storeyed
buildings degrades drastically under earthquake loading, due to buckling of bracings under …

This paper presents an experimental investigation of buckling restrained braces (BRBs) with
new end restraints and casing members (CMs). The component tests for ten BRBs with CMs …

The results of experimental tests carried out on reinforced concrete (RC) full‐scale 2‐storey
2‐bays framed buildings are presented. The unretrofitted frame was designed for gravity …

The seismic behaviour factor (R) is evaluated for steel X-braced and knee-braced RC
buildings. The R factor components including ductility reduction factor and overstrength …
