What is the bearing capacity of the roof of the house per square meter?

Generally speaking, the roof load is clearly stipulated in the building code. The owner's roof is generally 2.0kN/m2 and the non-owner's roof is 0.5kN/m2, which is converted into 200 kg per square meter of the owner's roof and 50 kg per square meter of the non-owner's roof.

The building belongs to barrier-free roof, which can be calculated according to 200 kilograms per square meter. The amount of earthwork and vegetation should not exceed this value, but should be calculated conservatively. Because the rainfall in summer and the snow in winter should also be considered, it is suggested that the unit earthwork should not exceed 0/30 kg per square meter/kloc.

Extended data:

Roof truss load-bearing refers to the structural mode in which a group of bars are combined with each other in the same plane to form an integral component roof truss, and load-bearing components (such as purlins) are placed on it to bear the roof load. This load-bearing method can form a larger internal space, which is mostly used in buildings that need a larger space, such as canteens and teaching buildings. ?

According to the different load-bearing parts, sloping roofs mainly include traditional wooden frame roofs, reinforced concrete roof trusses, steel roof trusses and membrane structure roofs developed in recent years. Transverse wall bearing is a structural way that the roof is built into a triangle according to the required slope, and the bearing members (such as purlins) are directly placed on the wall to bear the roof load. The bearing structure of the transverse wall is simple, the construction is convenient, the materials are saved, and it is beneficial to the fire prevention and sound insulation of the roof. Suitable for small rooms with a width less than 4.5m, such as houses, dormitories, hotel rooms and other buildings.
