How can I calculate Ss and S1 in pushover analysis in ETABS in asce41-13 NSP

• Pushover analysis in ETABS:
  • The method uses a pushover curve and its associated capacity spectrum curve to determine seismic demands.
  • The user must input a seismic hazard in terms of a response spectrum.
• Ss and S1:
  • Ss (the mapped spectral response acceleration parameter at short periods) and S1 (the mapped spectral response acceleration parameter at a period of 1 second) are required parameters for seismic hazard analysis in the United States.
  • They are used in calculating the design spectral response acceleration, which is then used in designing the structural system.
  • The seismic hazard is typically represented as an acceleration response spectrum that shows the maximum response of a range of different periods.
  • The values of Ss and S1 depend on the site location and soil conditions.
• ASCE41-13 NSP:
  • This refers to the seismic performance assessment of buildings, bridges, and other structures using ASCE 41-13 standard and its interpretations, including non-linear static procedures (NSP).
  • Non-linear static procedures are used to estimate the seismic demands on structures based on a simplified inelastic response analysis.

• The webpage provides a step-by-step guide for the calculation of Ss and S1 in pushover analysis in ETABS in asce41-13 NSP.
  • The guide explains that Ss and S1 are parts of the spectral response acceleration values.
  • The guide directs the user to use the software’s ASCE 7-10/16 Maps to get the spectral response acceleration values.
  • The user needs to input site-specific information such as Site Class, Risk Category, and Short Period Design Spectral Response Acceleration (Sds) in the software.
  • The software supplies the parameters required for the calculation of Ss and S1.
  • Ss and S1 are calculated using equations in asce41-13 NSP.
  • The calculated values of Ss and S1 can then be entered into ETABS to perform the pushover analysis.
