Tubular Brace Member Connections in Braced Steel Frames

cast connections. ABSTRACT: Diagonal bracings are extremely popular elements for lateral load resistance in steel-framed buildings. In turn, the most common shape used for bracing members is the hollow structural section. While the design of such members is straight-forward, the design of gusset-plate connections at the member ends is controversial. This paper reviews the current ‘state-of-the-...

an investigation on steel knee braced frames for lateral loads

hysteretic dampers as the most practical passive control methods have improved the seismic performance of steel structures through energy dissipation induced by large inelastic deformations. among them in this paper, kbf (knee braced frames), a special form of braced frames having a diagonal brace connected to a knee element instead of beam-column joint, is investigated. in such systems, the kn...

SEISMIC RELIABILITY ASSESSMENT OF OPTIMALLY DESIGNED STEEL CONCENTIRCALLY BRACED FRAMES

The main aim of this study, is to evaluate the seismic reliability of steel concentrically braced frame (SCBF) structures optimally designed in the context of performance-based design. The Monte Carlo simulation (MCS) method and neural network (NN) techniques were utilized to conduct the reliability analysis of the optimally designed SCBFs. Multi-layer perceptron (MLP) trained by back propagati...
