Case study 1 - Design of Pre-Engineered Building Steel Structure as per Indian Standards. The present study involves response spectrum analysis RSA and construction sequence analysis CSA , which are done on a setback steel structure and the structural analysis results such as storey displacement, maximum axial force, maximum shear force and maximum bending moment of the structural frame elements are compared. In general, the response spectra analysis procedure is based on the assumption that the dynamic response of a structural model can be approximated as a summation of the responses of the. Issue Team 4 on Response History Analysis. This is to convert the spectrum into required units and for the base shear to scale it to an appropriate level. Applications of these methods is essential in the seismic design of critical structures, such as nuclear power plants and petroleum facilities. We studied the performance of a 6 storied steel frame building with knee bracing system and compared with bare frame. Key words: Earthquake Engineering, Reliability Analysis, Earthquake Engineering, Fragility Curves, Shear Wall System, Flat Slab Structures. pdf Free Download Here Theory of Response Spectrum Analysis - EES Website. To compare equivalent static analysis and response spectrum analysis method on flat slab for above parameters.
