What are seismic parameters?

Seismic moment, corner frequency and seismic energy are inverted from the spectra that are corrected for the instrumental, distance and attenuation effects of each waveform and then averaged. Seismic source parameters are not measured, they are estimated. There is a difference between a measurement and estimation.

How is seismic design category determined?

What is a Seismic Design Category. If A Seismic Design Category is a classification assigned to a structure based on it’s occupancy category, and the severity of the design earthquake ground motion. Seismic Design Category A – Corresponds to buildings in areas where expected ground shaking will be minor. Good Soils.

What are seismic requirements?

Seismic codes or earthquake codes are building codes designed to protect property and life in buildings in case of earthquakes. The need for such codes is reflected in the saying, “Earthquakes don’t kill people—buildings do.” Or in expanded version, “Earthquakes do not injure or kill people.

Where can I find the USGS seismic parameters?

Most users obtain seismic design parameter values from the USGS web services through third-party GUIs like the following: 1 ASCE 7 Hazard Tool 2 SEAOC/OSHPD Seismic Design Maps Tool 3 ATC Hazards by Location Tool

Which is the best seismic design map tool?

Seismic Design Map Tool SEAOCC and OSHPD have developed this website interface that queries the U.S. Geological Survey (USGS) web servers and retrieves the seismic design variable in a report format. The website currently provides ASCE 7-16, ASCE 7-10, ASCE 41-13, ASCE 41-17, IBC 2015, IBC 2012, NEHRP-2015, and NEHRP 2009 seismic design map data.
