In this paper, the structural analysis software ETABS is used to analyze and design a G + 5 reinforced concrete residential building for vertical loads due to dead and live loads and horizontal loads due to earthquake and wind load. Jul 01, 2013 · ETABS manual - Seismic design of steel buildings according to Eurocode 3 & 8. Shear Wall Design Manual. Behavior of structure during earthquake motion depends on distribution of weight, stiffness and strength in both horizontal and vertical planes of building. Response spectra have also been obtained during the 1971 San Fernando earthquake as well as from other earthquakes in the Los Angeles, California area. ’s profile on LinkedIn, the world's largest professional community. The import of Revit Structure models from CSiXRevit has been enhanced to handle multi-story sloped columns and vertical planar walls with openings on their edges. The earthquake leads to random ground movements, which occur in all possible directions originating from the epicenter. designed for lateral loads of earthquakes / wind.
