Different Modes of Combination in Response Spectrum by SolidWorks Simulation
The response spectrum method is used to compute inertial response, estimates of response quantities developed for each mode, each direction of excitation and each input, if multiple inputs are considered. The total response is then formed by summing over all modal component, spatial component and excitation component responses. It estimate the structural response to short, nondeterministic, transient dynamic events. Examples of such events are earthquakes and shocks. Since the exact time history of the load is not known, it is difficult to perform a time-dependent analysis. It is a widely used procedure for performing elastic dynamic seismic analysis, represents the set of the maximum acceleration, velocity or displacement responses of a family of single-degree-of-freedom (SDOF) damped oscillators. Fig: 1 For a given time period of system, maximum response is picked. This process is continued for all range of possible time periods of SDOF system. Final plot with system time perio...
