Thaidavid-
Most of these structures are small and part of other projects and are architecturally driven. Can't use a pre-engineered buildings because of sometimes odd shapes, etc. So what I am looking for is a way of determining the reactions from the fabric on my structure. There are...
I don't know why things happen in clusters, but I am getting a number of requests for the design of framing to support fabric roofs. These are typically light-weight fabric with steel cable around the edges and no structure to give the fabric any shape. I am not sure of the amount of...
Good idea on the braces, but be careful what you attaching to. Pre-engineered building Z-purlins are not stable laterally, so you are depending on the diaphragm capacity of the roof deck to carry the lateral loads to the rigid frames, but many PEMB's use standing-seam roof systems that are...
Just to add to your worries, if the fabric "wall" is secured at both the top and bottom edges, it will generate an uplift at the bottom and a corresponding downward force at the top due to catenary action. This effect is frequently overlooked when dealing with fabric covered buildings and...
I would suggest that you start with ASCE7, which specifies minimum loads for structures, signs included. You will have to know the location in order to determine the required wind velocity, but you can get the required forces there. You will then have to check the sign (assuming it is...
