Performance-based Plastic Design Method for Buckling- Restrained Braced Frames
This paper presents the key design points of buckling-restrained braced frames (BRBFs) by using the performance-based plastic design (PBPD) methodology. This method is based on energy-work balance concept and uses pre-selected target drift and yield mechanism as design criteria. Based on multi-mode pushover and time-history analyses, a simple equation is developed for computing yield drift rati...
متن کاملSEISMIC TOPOLOGY OPTIMIZATION AND COLLAPSE SAFETY ANALYSIS OF CHEVRON BRACED FRAMES
This study is devoted to seismic collapse safety analysis of performance based optimally seismic designed steel chevron braced frame structures. An efficient meta-heuristic algorithm namely, center of mass optimization is utilized to achieve the seismic optimization process. The seismic collapse performance of the optimally designed steel chevron braced frames is assessed by performing incremen...
متن کاملDesign of Structural Braced Frames Using Group Optimization
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...
متن کاملConcentrically Braced Frames: European vs. North American Seismic Design Provisions
A critical review of seismic design provisions for concentrically braced frames (CBFs) in both European and North American (i.e. US and Canadian) codes is presented in this paper. Indeed, even though those codes are based on capacity design philosophy, different requirements and different approaches are used to guarantee the hierarchy of resistances between dissipative and non-dissipative eleme...
متن کاملImproved Seismic Performance of Chevron Brace Frames Using Multi-Pipe Yield Dampers
Spacious experimental and numerical investigation has been conducted by researchers to increase the ductility and energy dissipation of concentrically braced frames. One of the most widely used strategies for increasing ductility and energy dissiption, is the use of energy-absorbing systems. In this regard, the cyclic behavior of a chevron bracing frame system equipped with multi-pipe dampers (...
