OPTIMIZED MODELING AND DESIGN OF STEEL FRAMES IN DIFFERENT SEISMIC ZONES USING ETABS SOFTWARE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
In the Present analysis, a steel framed building with 15 floors (each story is 4m height) is analyzed and designed in all seismic zones by using software “ETABS” an engineering software product that caters to multi story building analysis and design. The project consists of design based on a set of user specified load combinations. The design involves calculating story drift, story shear, displacements in all seismic zones and comparing the results. Optimization is an act, process, or methodology of making something as fully perfect, functional, or effective as possible. In steel structures best way of modeling can be possible by effective placing of steel braces to counter the lateral forces acting on the structure. Lateral forces always try to overturn the structure so effective placing of braces is required. Diagonal braces can be placed in interior elevations of the building. The intent of the braced frame at this location was to provide resistance to lateral loads in both shear and overturning. The horizontal truss elements at the roof and mid-height of the building are transfer trusses to help distribute overturning forces from the interior braces to the building exterior
