What is a living burden?

Live load is the tension on the structure that varies due to changing circumstances. People inside the office building are an example of such a burden; They come and leave the building and move there during the day. Another example is furniture, as well as the accumulation of snow on the roofs and other environmental pressures. Buildings must be designed with regard to potential live loads, because the inability to adapt to the conditions of the shift can lead to structural failure. Designers must think about the nominal occupancy of the building, including the circumstances of special use that could change the load requirements. For example, factories are more likely to have heavy equipment that could add to live load. Likewise, a rehabilitation center with a capacity of 70 people could contain a number of people in energy trucks, with a combined weight higher than the weight group of individuals.

This is unlike a dead load that is solid. The weight of the building itself is soupart of the dead load, as well as accessories that are functionally fixed on the spot. For example, built -in wardrobes and counters could be theoretically removed, but will probably remain in place for a long time. These loads behave statically and are easier to design because the engineer can calculate the solid trunk they develop and take into account it in the design plans.

Live loads are around, which has the potential to pose some problems. They can change stress formulas in the structure and can sometimes weigh some areas more than others. A classic example can be seen in the snow, which is collected on the roof of buildings. In an area where snow is rare and engineers do not consider the risks, in abnormal winter weather the collapse of the cesspudes may not be prepared for live load. The load movements in the structure over the stairs and elevators can cause problems by moving the weight distribution.

toleRance for engineering must be very high for safety reasons. When engineers are considering the potential live load of the building, they must propose a load exceeding to be safe. This ensures that the sudden movement of the piece of equipment will not break through the floor, or that a heavily loaded elevator does not interfere with the building when it throws on the shaft.
