PERFORMANCE-BASED CONNECTION TOPOLOGY OPTIMIZATION OF UNBRACED AND X-BRACED STEEL FRAMES
The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...
متن کاملTubular 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-...
متن کاملSEISMIC 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...
متن کاملEarthquake Response Evaluation of RC Frames using High Strength Steel
To achieve better structural performance, lesser damage along with minimum residual displacements is a main objective of earthquake resistant design. In ordinary steel reinforced concrete frames, chances of severe damage because of the lower strength of conventional steel are always present during strong earthquakes. With the invention of high-strength steel (HSS) it can be anticipated that its...
متن کاملSeismic Yield Displacement Profile in Steel Eccentrically Braced Frames
Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...
