Document Summary
There are two main categories of loads on structures: Dead loads: weights of various structural members and any objects that are permanently attached to the structure. Superimposed dead load (floor finish, partition, ceiling, equipment, etc. ) Live loads: can vary both in magnitude and location. Wself weight = 0. 2 m * 24 kn/m3. Wsdl = (carpet) + (duct & support) + (ceiling) = 0. 1 kn/m2 + 0. 3 kn/m2 + 0. 5 kn/m2. Live loads come from the national building code of canada. It provides minimum required design loads based upon building type. If we know the building type, the we can do anything. There is also formulas on the nbcc to calculate environmental loads like wind and snow and seismic loads. For highway bridges, there is the canadian highway bridge design code (csa s6) with more specific information. Determination of reactive forces and internal forces for structural members. Calculate stress and make sure that the stress is below the allowable stress.
