SEAOCC Mission Statement

SEAOCC is the Central California section of the Structural Engineers Association of California (SEAOC). Our member organization serves structural engineers and communities the inland areas of Central and Northern California and Nevada. The Association and was established for the following purposes:

To advance the science of structural engineering; to assist the public in obtaining dependable structural engineering services; to encourage engineering education; to maintain the honor and dignity of the profession; to enlighten the public regarding the province of the structural engineer; to advance proper legislation and to oppose improper legislation affecting structural engineering practice; to cooperate with other professional organizations; to cultivate social contacts within its Membership and by closer association and a better mutual understanding to discourage unethical and detrimental practice.

To afford the public a reasonable assurance of the ability and integrity of its Membership by requiring that those admitted shall have established and shall maintain a high professional reputation.

SEAOC Seismic Design Map Software -BETA Version - Click Here

USGS is planning to phase out the web tool for finding seismic design variables. The background data will still be accessible at the USGS website, but there won’t be an interface website. ASCE developed a web tool that includes seismic maps but it has a subscription fee to use. SEAOCC and OSHPD developed a web interface that will be able to ping the USGS webservers and retrieve the seismic design data in a report format. The website is in development stage, a beta version is available to all members at the SEAOCC website. 

The website currently provides ASCE 7-16, ASCE 7-10, IBC 2015, IBC 2012, NEHRP-2015, NEHRP 2009 seismic design map data. We are in the process of adding ASCE 41-13, ASCE 41-17 and ASCE 7-05 seismic design map data. We’ll add more reference documents to the website as USGS adds more reference database to their server. The website will eventually find a permanent home, still free to all, possibly on the SEAOC website or ATC website. This website is open-source, currently hosted via GitHub. If you have any JavaScript improvement suggestions, we’d like to hear from you.
