1. dead load: the floor load is 2.0kN/㎡, which is the self-weight of the professional floor practice of architecture, and the purpose is to leave appropriate room for decoration, excluding the self-weight of the floor structure and the weight of the floor bottom practice. 2. The self-weight of the light partition wall in the house, whether it is a light partition wall or a partition wall that may be flexibly and freely arranged, is regarded as a dead load, with a value of 2.0kN/㎡. 3. The live load of the house is also 2.0kN/㎡ (three 2.0kN/㎡: deadweight of floor slab, deadweight of light partition wall, live load value). 4. The dead load of the roof is 4.0kN/㎡, the live load of the roof is 2.0kN/㎡, and it is 0.5kN/㎡ when it is unoccupied (for the roof with light steel structure, it must be specified in No Overloading) 5. There are three data to remember: 2.5kN/㎡, 4.0kN/㎡, 7.0 kn/㎡ and 2.5 kn/㎡, which are applicable to floors where people or things may be concentrated, such as general stairs, general balconies, general toilets, general kitchens, conference rooms, reading rooms, hospital clinics and classrooms. 4.0kN/㎡ is suitable for floors where people or things may be concentrated and dense, such as gymnasiums, stands, dance halls, shops, passenger waiting rooms, exhibition halls, fire evacuation stairs, etc. 7.0kN/㎡ is used for two machine rooms and one transformer room, namely ventilation equipment room, elevator room and high voltage transformer room. Because these places not only have the load of equipment, but also the load of equipment foundation is very large. 6. Underground roof, or about 0.000 slab, with live load of 8~ 10kN/㎡. Because when the construction reaches 0.000, the construction unit often piles all the engineering data on the underground roof, which is convenient for construction to take at any time and anywhere. At the same time, it should be noted that when the live load of+/-0.000 slab is 8~ 10kN/㎡, the dead weight of partition wall under dead load can be 1.0kN/㎡ or less, because the construction of partition wall will not be completed when a large number of building materials are stacked. (When designing a 0.000 slab, the reinforcement of slab and beam is often larger than that of other floors with the same cross-sectional size) Concept first, calculation second.
