Enlarged ASCE 7 Basic Wind Speed Map

[clandry]

Does anyone know a source for a higher definition Basic Wind Speed Map for the ASCE 7. I have an electronic (.pdf) version of ASCE7-05, but when I zoom into the map, it gets really distorted. I am interested in the New Orleans, LA area.

Thanks in advance for your assistance.

The Louisiana building code should have the best maps. - but they might be based on ASCE-7 or, last I checked, with IBC 2000 (I think the LA code cites that version).

Is the information on Fig. 6-1a really that difficult to interpret? If you're right on the line, go with the higher value.

I'm not familar with that many Louisiana Building Codes, but a lot of the time the local building code will take the decision out of your hands and impose a design wind speed. Take a look at the city's website.

Doesn't anyone google anymore?

Looks like they're going with IBC 2003.

In Florida the state has been broken county by county for wind speed demarcation. They are very useful and I use them all the time.

Here is a link to the Florida county wind speed maps:

I also call the local building officials, for areas that I am not familiar with, and chat with them about their unique local requirements.

By the way, the ASCE wind speed map is an approximation that allows for interpolation between the lines. One must always call local building officials if they are not certain.

Orleans Parish permits dept. requires a 130 mph wind speed for design.

Thanks for the information.

The LSU website has the wind speed contours superimposed on a state map, so you can tell which zones specfic towns, parishes, highways etc. are.

Hi! Spider Web Structure and its application to a hurricane proof building. This is the Science Fair Topic my 12 yr. old son has chosen. Could you give me some tips on a procedure to build a model. Should he use the spider web structure as the structural support of the building model and then use legos to hang on the structure or build a model with legos and wrap the web structure on the outside.

Any suggestions on the material that he should use in his model to build the spider web structure. Any suggestions are greatly appreciated

Have you talked with Charlotte's Kids construction? They're the experts in "sticky-tension" structures. I don't know their URL, but they're on the web...
