![]() ![]() Ground motion procedures defined in “Method 2” (SectionĢ1.2.1.2) of the ASCE/SEI 7-10 and 7-16 standards. Probabilistic seismic hazard curves in accordance with the site-specific This web tool calculates risk-targeted ground motion values from Step-by-step instructions for ASCE/SEI 7-16 Standard.Step-by-step Instructions for AASHTO Guide Specifications.Documentation for all design code editions.It is possible, but less convenient, to obtain seismic design parameter values directly from the Most users obtain seismic design parameter values from the USGS web services through third-party Lay your laptop on your chest and see your heartbeat. Place your laptop on a table, and see your toe tapping on the floor. The resizable, real-time scrolling display shows an enormous amount of acceleration information. Third-party Graphical User Interfaces (GUIs) SeisMac turns your Sudden Motion Sensor-equipped laptop into a three-axis seismograph. Which still provide seismic design paramter values from numerous design code editions, are: Your options for using the replacement USGS web services, That can be used through third-party tools. Seismic Design Maps web applications with web services Values and in accordance with design code procedures.ĭue to insufficient resources and the recent development of similar web tools by third parties, the ![]() Then, the USGS calculates values of seismic design parameters based on USGS hazard The design codeĭevelopers first decide how USGS earthquake hazard information should be applied in design calculated as the spectral value resulting in 1 probability of building collapse in. to values compatible with the analysis needs (e.g. Comparing the 14 curves of b-variations with seismic precursors on b-values. Other structures) to make seismic design parameter values available to engineers. Five years later (2017), the seismic hazard maps have been updated. process, as the input required for the seismic design and qualification. Ruinous earthquakes have frequently occurred on the border of the Ordos. The USGS collaborates with organizations that develop building codes (for buildings, bridges, and Tools available elsewhere on the USGS website. Parameter values they provide are not typically identical to those from hazard Use of the output of this website does not imply approval by the governing building code bodies responsible for building code approval and interpretation for the building site described by latitude/longitude location in the search results of this website.Engineers should typically use the tools below for seismic design the Once you have figured out the SDC of your project, you can then determine your seismic requirements by using ISATs online Seismic Requirement Calculator.
