ATC Hazards

The Applied Technology Council (ATC) has made a web tool for determining structural hazards by location. This is a useful tool to document code specified design values for snow, wind, seismic loading criteria. You can find their tool at .

About the ATC:

The Applied Technology Council (ATC) is a nonprofit, tax-exempt corporation established in 1973 through the efforts of the Structural Engineers Association of California. ATC’s mission is to develop and promote state-of-the-art, user-friendly engineering resources and applications for use in mitigating the effects of natural and other hazards on the built environment. ATC also identifies and encourages needed research and develops consensus opinions on structural engineering issues in a nonproprietary format. ATC thereby fulfills a unique role in funded information transfer.

ATC is guided by a Board of Directors consisting of representatives appointed by the American Society of Civil Engineers, the National Council of Structural Engineers Associations, the Structural Engineers Association of California, the Structural Engineers Association of New York, the Western Council of Structural Engineers Associations, and four at-large representatives concerned with the practice of structural engineering. Each director serves a three-year term.

Project management and administration are carried out by a full-time Executive Director and support staff. Project work is conducted by a wide range of highly qualified consulting professionals, thus incorporating the experience of many individuals from academia, research, and professional practice who would not be available from any single organization. Funding for ATC projects is obtained from government agencies and from the private sector in the form of tax-deductible contributions.

The corporate headquarters for ATC is located in Redwood City, California, with a satellite office in Arlington, Virginia.

AISC 2013 Spring Seminar Series

AISC has announced their new spring seminars.

(Chicago, IL) – This season, become more informed, more efficient, and a better structural engineer with AISC’s annual Spring Seminar Series. No matter what type of building you’re designing, nowhere else will you learn to leverage your professional knowledge with the 14th Edition Steel Construction Manual, apply welding applications for cost-efficient design or delve into design concepts and connections for seismic braced frames – all while learning from masters in these topics, in person. Organized by the American Institute of Steel Construction (AISC), the Spring 2013 Seminar Series will be offered in 12 cities around the U.S. from March to June. Act now and you’ll receive a $50 early registration discount when you register at; the discount is valid until February 22.

This year’s AISC spring seminars include:

2010 Specification and 14th Edition Manual: The Louis F. Geschwindner Seminar

Listen to the Steel: Duane Miller on Welding

Seismic Braced Frames – Design Concepts and Connections

Effective Steel Design with Seismic Considerations

Each lecture also provides useful tools and resources including course notes, design examples and AISC publications.

Why we need building permits

This is a very good example of why we need building permits from Asheville’s Citizen Times:

ASHEVILLE — The collapse of a downtown building might have been avoided if a contractor had gone through the proper permitting process, the head of the city’s Development Services Department said Friday.

Before a permit was issued, the city would have required that an engineer prepare plans that would include measures to ensure the structural integrity of the 1917 building during renovation, department head Robert Griffin said.

Odds are that following those plans would have prevented the Thursday collapse, he said.

Asheville fire officials say demolition work had been underway inside the building for about the last week.

People who heard about the collapse on Facebook gathered in a courtyard that was strewn with bricks from the collapsed building to get a look at the damage.

Calculator to Estimate Time to Freezing for Water in an Insulated Pipe

The Whole Building Design Guide ( has updated their online calculator to estimate time to freezing for water in an insulated pipe.

Reference: 2009 ASHRAE HoF, Chapter 23, Equation 1 (pg 23.4)

This calculator estimates the time for a long, water-filled pipe or tube (with no flow) to reach the freezing temperature.

Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05)

AISC Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05) are available on the AISC website for free.

This ANSI-approved specification is a companion to the Specification for Structural Steel Buildings (ANSI/AISC 360-05) that extends coverage to the connection detailing and member design requirements for structural steel and composite structural steel and reinforced concrete systems in high-seismic applications. This new standard, dated March 9, 2005, replaces and updates the 2002 Seismic Provisions for Structural Steel Buildings as well as incorporating provisions for two new systems: buckling-restrained braced frames and special plate shear walls. Supplement No. 1, dated November 16, 2005, is incorporated into the new seismic provisions which affects only the section on ordinary concentrically braced frames (OCBF). (5.2MB, 330 pages )
