Practical Recommendations for the Preliminary Design Analysis of Multi- Story Moment-Resisting Frames
Approximate methods of analysis are essential tools at the preliminary design phase of any building project. For multi-story multi-bay lateral-force-swayed frames, the available classical approximate methods are the Portal and the Cantilever techniques. It is known that the Portal method gives more accurate results for low to medium rise frames. This investigation showed that it is possible to ...
متن کاملRobustness Assessment of Steel Moment Resisting Frames
Nowadays, many buildings with steel Moment Resisting Frames (MRF) are built in seismic zones when seismic codes are at its early stages of development, and as such, these structures are often designed solely to resist lateral wind loads without providing an overall ductile mechanism. On the other hand, current seismic design criteria based on hierarchy of resistance allow enhancing the structur...
متن کاملSeismic Behavior of Asymmetric Two-Story X-braced Frames
Concentrically braced frames (CBFs) are one of the efficient lateral load resisting systems in high seismicity regions. One of the common problems with the use of concentrically braced frames is limitation in the architectural application and position of the openings. Two-story X braced frames have more advantages than other configurations of concentrically braced frames, since in many cases th...
متن کاملERFORMANCE-BASED SEISMIC DESIGN OPTIMIZATION OF COMPOSITE MOMENT RESISTING FRAMES WITH CONCERETFILLED STEEL COLUMNS AND STEEL BEAMS
In this paper, an optimization framework is developed for performance-based seismic design of composite moment frames consisting of concrete filled steel box columns and I-shaped steel beams. Material cost of the structure and seismic damage under severe earthquake ground motions are minimized as objective functions. Two design examples are presented to demonstrate the applicability and efficie...
متن کاملA Technique for Seismic Rehabilitation of Damaged Steel Moment Resisting Frames
Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...
