Find the column for your dead load and spacing, and the row for your timber size to find the permissible clear span in metres. In the field of construction, understanding the concept of dead load and live load is crucial for ensuring the Dead load refers to the permanent, static weight that a structure must bear throughout its existence. Total truss load (live + dead) = 50 psf. It’s important to distinguish between live load and dead load since the latter describes the weight of all transient loads placed on the structure, including visitors, Load on the pink trusses = normal roof load calculation + a point load from the blue trusses. For example, the dead load of a slab is usually calculated as an area load (kN/m 2) because Computing the unit dead load for a region of surface area generally starts by identifying the region of a roof plan, floor plan, or elevation where the unit load is needed then looking at a typical section of that area to see how it The following calculations have been undertaken for the proposed alterations at the above address.
