I am designing aluminum screen enclosures in Florida. The aluminum members are thin walled, self mating sections (two C channels that overlap to form a hollow box. THe most common roof shape is a mansard beam. The beam is connected to the host structure at one end and an aluminum post at the...
I would some opinions on whether or not a splice at a gable or mansard style roof should be considered a moment connection. This is for aluminum design of hollow self-mating sections (two C shaped stitched together) usually spiced with a gusset plate. Obviously at, say, the center of a flat span...
Does anyone have any references on calculating deflection due to shear stress? I am looking for deflection due to uniform load, simply supported beam for a sandwich panel (aluminum skins with EPS core). Thanks for any input.
Any suggestions for designing wind load forces on a 6' aluminum fence (2x2 posts with (15) 5/8" square pickets)? I have a client that wants this fence engineered for 110 mph wind load according to the new Florida Building Code. Using ASCE 7-98, I ran numbers using the Trussed Tower...
I need some expert opinions. I have a client that installs sun rooms (aluminum framing, glass windows, composite roof structure). We now have a new building code in effect in Florida (The Florida Building Code). Previously, these rooms were not treated as "additions" to the home...
I am designing a gazebo structure for the wind loads of Florida. The gazebo will generally be 8-sided with screen as an option. I don't have a problem getting the wind loads, but have some questions on the design.
What are the accepted assumptions for a free standing strucure? For an open...
What is the correct way for calculating the wind load on the overhang using ASCE 7? I have gotten conflicting opinions about using the overhang wind load or adding the overhang wind load to the roof load.
I am checking the bending stress on a truss overhang. Can anyone tell me the types of lumber that are typically used in truss design? The truss drawings are unavailable. I figured it's probably Southern Pine or Spruce-Pine-Fur. The project is in Florida. I will of course be conservative if I...
I am a structural engineer and I design screen enclosures typically for pool areas which attach to the fascia board of the home. My question regards capacity of the house truss to take the additional wind loads (up and down)from the enclosure. (A typical load is 150 lb/ft of fascia or 1350 lb at...
