Total load on the purlin normal to the rafter w e w cos θ.

Refer to robert west drawings no. 3095 003 1010 1011 and 5010 for proposed replacement roof details actions permanent load roof finishes. The purlin is thus subjected to biaxial bending. The loads on building may be a residential or any type of structure are mainly classified into vertical and horizontal loads the vertical loads are the dead and live load.

Types of loads on column. The bending stresses about both axes of bending are determined. Is the total structural dead weight sufficient to prevent flotation of the house from the buoyancy. Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits.

Calculation of building loads. Total structure dead weight. Total load of slab dead load live load self weight the columns are also subjected to bending moments which have to be considered in the final design. D dead load l live load l r live roof load w wind load s snow load e earthquake load.

Self weight of beams per running meter. Vertical loads on the house excluding buoyancy force 5. The above calculated load of 30 kn can be further converted in udl of 5 kn m by dividing it by member length as shown above. The resultant stress shall not exceed the permissible value.

Load on 4 m span area of triangle x thickness of slab x density. Total load on the purlin parallel to the rafter w sin θ. Dead load comprise the weights of the roofing the purlins the joists and the rafters that support the joists or purlins or the truss that support the purlins. Refer to document knuk des cds 189 0003 rev 04 for conceptual design statement.

In this article some of many other important loads are also explained. The horizontal loads are the earthquake and the wind loads. Roof load is dead load and live load. Requirement for a design of replacement upper roof.

Self weight of the column x number of floors. Floodproofing design depth. Force during a flood event. Load types loads used in design load equations are given letters by type.

Total vertical flood load due to buoyancy. This is the general classification of loads. To find the dfe use equation.
