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 https://hazards.atcouncil.org/#/ .

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.

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.

LEAP Bridge Enterprise Release V12.01.00

LEAP Bridge Enterprise V12.01.00 is now available.  In addition to bug fixes, and code updates, some of the enhancements include the following:

LEAP Bridge v12.01.00.57

Enhancements:

  • Introduced a new analysis option “Integral Abutment Bridge” in the Project tab. This option allows users to analyze and design integral abutment

LEAP CONSPAN v12. 01.00.57

Enhancements:

  • CONSPAN has been updated to comply with the AASHTO LRFD 6th edition. Primary changes are minimum reinforcement requirement changes and Mcr calculations.

LEAP CONBOX v12. 01.00.57

 Enhancements:

  •  CONBOX now offers three types of temperature loading, including uniform temperature, linear gradient and multi-linear gradient temperature. Multi-linear temperature loading complies with AASHTO, CHBDC, and IRC codes.

LEAP RC-PIER v12. 01.00.57

Enhancements:

  • For integral abutment bridges RC-PIER performs a 3D frame analysis. In the 3D analysis each abutment and pier is part of the full bridge model and is subjected to the loads generated through RC-PIER. Model tab displays both the 3D model and the specific abutment or pier 2D frame with the node and member numbers referenced in the analysis reports.

Geometry Module: GEOMATH v12. 01.00.57

Enhancements:

  • Update for wall pier and pile bent.

How to Apply Wind Loads in RISA-3D – RISA News

RISA News has come with a new tutorial on applying wind loads.

Wind loads can be automatically are generated in RISA-3D for building models. RISA calculates the ASCE 7 Main Wind-Force Resisting System loads and calculations are based on the Analytical Procedure for Enclosed Rigid Building for All Heights.

The model has to have a Rigid Diaphragm in order to calculate the wind loads at each floor level.

To apply the wind loads select the Insert drop down menu and select Wind Load. This will open the Wind Load Generator, where you can add all the parameters based on you building location and conditions. The Base Elevation can be used to set the “ground elevation or the lowest point of wind exposure. This is helpful if you are modeling the basement level of the building.

Why is Plate Meshing Important?

RISA News has published an article on why plate meshing is important.  Basic understanding proper plate meshing is required to get reliable results on or Finite Element Mesh.  Without proper meshing of plates, inaccurate results are sure to follow.  Their example shows how too coarse of a mesh can result in stresses that are only half the magnitude of the actual solution.

As a rule of thumb, if the results change by less than 10% when doubling your mesh you can probably stop submeshing at that point.

How to Append or Merge Multiple Models Together in RISA-3D

RISA News has posted a how-to on appending and merging multiple models into a single model file.

RISA-3D allows you to append, or merge, multiple models into a single model file. This may be helpful if you model single floors in separate files and want to stack them together.

Before appending the files together you must be sure that each file has the same Units and Global Axesdefined. Once this has been verified, open a model and go to File > Append. Then choose the model you wish to add to the currently open model.
