Etabs (Atkins) J The following topics describe key parameters for the response spectrum case data: This definition will help to differentiate between the live loads that are NOT permitted by the code to be reduced. A Response Spectrum Analysis requires the specification of an excitation spectrum, also known as a frequency-acceleration spectrum. Static analysis, Response spectrum analysis) derived from SAP2000/ETABS can be imported in SCADA Pro and the corresponding P-M-V diagrams or the deformed shape to be displayed. The appropriate scale factors for response spectrum analysis was determined, by scaling between average story acceleration from nonlinear response history analysis and response spectrum analysis since the inertial forces were governing the design rather than. Response spectra can be requested either for a single time history function or a set of them. To investigate the seismic performance of a multistorey structural building with normal and oblique column by Response Spectrum analysis. Load Case Data - Response Spectrum. Lets assume the excitation angle = 0 and building principle direction is u1 So I will apply response spectrum function (per IBC 2006) in u1 direction by a scale factor.

Baker Department of Civil and Environmental Engineering Stanford University ABSTRACT: Earthquake engineering design requires an evaluation of the structure’s reliability over future seismic loads.
