The load-bearing part of the floor slab vertically divides the house into several floors, and the vertical load of people and furniture and the weight of the floor slab are transferred to the foundation through walls, beams or columns. According to the materials used, it can be divided into wooden floor, brick arch floor, reinforced concrete floor, steel liner bearing floor and so on.
In addition, the bearing standard of the office building floor is 2.5 kn/m2. The fixed load is the floor weight, plastering load at the bottom of the slab and plane layout, depending on the design thickness (generally within the range of 100-200mm), which is about 4-6.5 kN/m2 (about 400-650 kg/m2). The total is about 6.5-9 kN/m2, about 650-900 kg/m2.
Extended data
According to the Code for Load of Building Structures, the general live load of civil buildings is 2.0 kn/m 2, that is, a square live load is 200kg. When calculating the bearing capacity of the floor, this load must be multiplied by a load subentry coefficient, which is generally 1.4.
Calculation of bearing capacity: the sum of static load and live load on bearing floor or structure. For example:
1, residence, dormitory, hotel, office building, hospital ward, nursery and kindergarten 2.0(kN/m2)
2. Classrooms, laboratories, reading rooms, conference rooms and hospital clinics. 2.5 kn/m2
3, canteen, canteen general information file 2.5(kN/m2)
4. Auditorium, theater, cinema, fixed seat stands, public laundry 3.0(kN/m2)
5. Shops, exhibition halls, stations, ports, airport halls and their passenger waiting rooms, stands without fixed seats 3.5(kN/m2)
6. Gym, Performance Stage and Ballroom 4.0(kN/m2)
7, stacks, archives, storage room 5.0(kN/m2)
