i want to know few calculations done in construction sites
If there is no limit on how much glue you can use I would make several layers on both the top and bottom of the envelopeThis will help it act like an I-beam in the section with the glue; it will have a top layer that will be in compression and a bottom layer that will be in tensionAlso, it will have some shear resistance on the ends where the envelope is supportedIf there is a limit on glue I would put all the glue on the bottom and put additional layers near where the weight will be supported (probably the center).
This Site Might Help YouRE: Manilla folder bridge design? For my physics class, we have to build a quot;bridgequot; that can cover a 26 inch gapOur only materials are one manila folder, and regular glue(like Elmer's.) the only way weight can hurt is if I overuse glueThe max weight is undecidedAny suggestions on types of bridges.
Not quite sure where you're coming from, but some of the things you might need to calculate/check on site are: - Ground bearing pressures under cranes - Rigging/lifting calcs - Checks on beams etc that are subject to temporary loads - Checks on underground pipes, culverts etc that might be subjected to construction loads - Temporary works calculations Hope that helps.
