Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

This paper highlights aspects of the development of self-stabilizing links having tubular cross-sections for use in eccentrically braced frames (EBF’s). EBF’s utilizing this type of link could be used in bridge piers or other applications where lateral bracing to prevent lateral torsional buckling is difficult to provide. The development of design recommendations for these types of links consis...

Though topology optimization has been applied to many fields, ranging from mechanical to aerospace engineering, more work must be done to tailor it to the needs of the structural engineer, especially in regards to the design of high-rise buildings. Thus, this work aims to improve its application to structural engineering by describing an integrated topology optimization approach involving conti...

In recent years, it is considerably attempted to develop the concept of energy dissipation as an applicable technology to overcome the energy released by earthquakes. The passive control systems such as metallic dampers have been widely considered. The dampers are basically used to mitigate the structural responses and reduce the damages in main structural elements by energy dissipation. ...
