This paper presents the behavior and design concept of an efficient structural steel system
based on the applications of buckling-restrained knee braces (BRKBs). The advantages of a …

The attachment of supplemental knee braces is an efficient seismic retrofitting measure for
existing steel buildings. A new ductile knee brace with a built-in comb-shaped damper is …

A buckling-restrained knee-braced frame (BRKBF) is an efficient structural system utilizing
short buckling-restrained braces (BRBs) as knee bracing elements. Because of the shorter …

Abstract The Performance-based Plastic Design (PBPD) Method is a practical seismic
design and evaluation approach based on an energy concept. The required frame strength …

In the past two decades, extensive research has been conducted to evaluate the seismic
performance of Knee-element Connection Frames (KCFs) and to determine the most …

This paper investigates the seismic performance of an old school building with open ground
storey. The building was designed according to an old Egyptian design code that did not …

This article proposes an innovative steel modular MRF with knee brace elements for seismic
applications called Moment-Resisting Knee Braced Frame (MKF). In this system …

This study presents a design method for the seismic retrofit and rehabilitation of steel
moment-resisting frames (MRFs) with composite steel–concrete beams using the minimal …
