![]() ![]() ![]() ![]() Most loads are distributed or are treated as such, for example wind or soil pressure, and the weight of floors and roofing materials. Distributed (or surface) loads that act over a surface area.Line loads that act along a line, for example the weight of a partition resting on a floor, calculated in units of force per unit length.Concentrated loads that are single forces acting over a relatively small area, for example vehicle wheel loads, column loads, or the force exerted by a beam on another perpendicular beam.In structural analysis three kinds of loads are generally used: The magnitudes of these loads are not known with great accuracy and the design values must depend on the intended use of the structure. The weight of occupants, snow and vehicles, and the forces induced by wind or earthquakes are examples of live loads. On the other hand, live loads (LL) usually vary greatly. Dead loads (DL) are essentially constant during the life of the structure and normally consist of the weight of the structural elements. Loads are usually classified into two broad groups: dead loads and live loads. Loading conditions on the same structure may change from time to time, or may change rapidly with time. The nature of the loads varies essentially with the architectural design, the materials, and the location of the structure. The determination of the loads acting on a structure is a complex problem. ![]()
