ASCE 7-16 Site Seismic Data

The SkyCiv Load Generator uses seismic parameters obtained from U.S. Geological Survey (USGS) Web Services. This is the same database used in ASCE 7 Hazard Tool. Users will get the following data that can be modified to get the most appropriate seismic load for the structure:

  • Long-period transition period \( {T}_{L} \)
  • Design spectral response acceleration parameter at short period, \( {S}_{DS} \)
  • Design spectral response acceleration parameter at 1s period, \( {S}_{D1} \)
  • Mapped maximum considered earthquake spectral response acceleration parameter, \( {S}_{1} \)

NBCC 2020 Site Seismic Data

The SkyCiv Load Generator uses the Canada’s 6th Generation seismic hazard model (Kolaj, Halchuk, and Adams, 2023) in determining the site seismic data for a specific location. These data is then processed in our server to generate the appropriate for the specified location. A comparison of site seismic data of select locations and the data obtained from SkyCiv Load Generator can be viewed thru the link below.
