wind load
how can apply wind load to a regular truss if i have a 110 mph wind exp "c"
check out our whitepaper library.
refer to asce 7 for application. in general, you will have to apply factors to the wind load depending upon wind direction and shape of structure. you will also have to check at least two directions, perhaps more depending upon configuration of the structure.
my concern is that if you are asking this question in a forum, you have no one to check and mentor you through this process. this can be a bit tricky depending on many factors and should be done by a structural engineer. if you are not a structural engineer, get some help with it.
i know that,but the thing is i'm not a very good english speaker
pawis2k:
ron is correct. asce 7 (preferably 7-95) is essential to your answer.
the load on a lattice truss is heavily dependent on the shape of the truss
check your local building code. some (such as ny state and massachusetts) have wind load pressures already listed. how high up is your truss, pull the design wind loading off the chart, apply it to your vertical projected area, and badda boom - badda bing, your off to the races.
there are spreadsheets available at
ron was right you should review asce 7 and take a course on line visit their website
