ETABS Tutorial 6: How to Develop the Design Response Spectrum According to ASCE 7-10/ ASCE 41-13?

Learn how to develop design response spectrum curves in ETABS software, following the guidelines of ASCE 7-10 and ASCE 41-13. This tutorial demonstrates the step-by-step process of creating response spectrum curves for both 5% and 2.5% damping ratios as specified in ASCE 7-10 and ASCE 41-13, respectively.

I use Response Spectrum function from ASCE 7 for my project. and i am using scale factor 9,81 as recommendations of CSI when defining the response spectrum load case, but I want to know the rational beyond that because response spectrum curve is defined as a fraction of graviotanal acceleration as Ss and S1 are function of G?

Response spectrum is a fundamental tool in structural engineering used to assess how a structure or system will respond to seismic or dynamic ground motions, such as those generated during earthquakes. It provides valuable insights into the structure's behavior by representing the maximum response at various natural periods of vibration. The concept of response spectrum analysis is based on the understanding that different structures have different natural frequencies of vibration, and these frequencies influence their response to external forces.
The response spectrum is commonly used to represent the structure's response in terms of acceleration, velocity, or displacement. Each of these response spectra is plotted against the corresponding natural period of vibration of a hypothetical single-degree-of-freedom (SDOF) oscillator. In a response spectrum analysis, the ground motion records are either derived from historical earthquake data or synthetic ground motion models.
The ASCE 7 standard, widely used for seismic design in different countries, provides specific response spectra for different ground motion parameters. These parameters are often denoted as Ss (short-period response spectrum) and S1 (1-second period response spectrum). The values of Ss and S1 depend on the seismic hazard and design category of the structure's location.
Response spectra are typically expressed in terms of gravitational acceleration units (g). The gravitational acceleration constant, denoted as "g," is approximately 9.81 m/s^2 or 32.2 ft/s^2, depending on the unit system used (SI or Imperial).
