Analysis & Design of Omrf & Smrf Structural System for Steel Buildings Using Is 800-2007
Abstract
The objective of this study is to investigate the seismic behavior of the structure i.e... OMRF (Ordinary moment resisting frame) & SMRF (Special R C moment Resisting frame). For this purpose 5th, 10th, 15th , 20th storied structure were modeled and analysis was done using Staad.Pro software and using the codes for analysis, IS 1893:2002, IS 456: 2000. The study assumed that the buildings were located in seismic zone II (Visakhapatnam region).The study involves the design of alternate shear wall in a structural frame and its orientation, which gives better results for the OMRF & SMRF structure constructed in and around Visakhapatnam region. The buildings are modeled with floor area of 600 sqm (20m x30m) with 5 bays along 20 m span each 4 m. and 5 bays along the 30 m span each 6 m. The design is carried out using STAAD.PRO software. Shear walls are designed by taking the results of the maximum value of the stress contour and calculation are done manually by using IS 456-2000 and IS 13920-1993. The displacements of the current level relative to the other level above or below are considered. The preferred framing system should meet drift requirements.
- 1. Up to 20 floored building subjected to seismic load for Visakhapatnam without shear wall
- 2. Up to 20 floored building subjected to seismic load for Visakhapatnam with shear wall
