Trapezoidal formula =W * Lx / 6 [ 3-( Lx/ Ly )2 ] Triangular formula = W * Lx / 3 Rectangular formula = W * Lx / 2 15. As previously stated, the use of an equivalent uniform live load is not appropriate for a CMFS due to the large track forces. Dead load is distinguished from live load by the fact that the live load will change depending on the environment around the structure. Self weight of slab acts: This load acts as UDL, this is calculated after assuming the 1m wide square strip and suitable thickness consideration. Post-tensioned (PT) slabs PT slabs offer the thinnest slab type, as concrete is worked to its strengths, mostly being kept in compression. This load also acts as UDL. LOAD PATH AND DETAILING Prior to the calculation of the design. Thus, to optimize the value (i. 3 The slab is designed based on 1-foot strips, therefore the live load most be distributed to these strips. 00 (self-weight) + 4. The distribution for shear is; be = b m. The discussed calculations involve equations that represent load Reactions. While Celotex PIR boards have a good compressive strength, they cannot be laid below a raft slab and take the structural load of the building. 1, the minimum uniformly distributed live loads and minimum concentrated live loads are as follow: Occupancy or Use Uniform (psf) Concentrated (lbs) Office building Office Lobbies and first-floor corridors Corridor above first floor 50 100 80. Ribbed and waffle slabs They provide a very good form of construction where slab vibration is an issue, such as laboratories and hospitals. Punching shear calculations are provided for columns/pedestals that land on concrete slabs. (2) Loads (a) Determination of loads (gravity, wind, snow, earthquake) (b) How are loads carried from the floor slabs, to the joists and beams, to the columns, and then to the foundation. It is important to list live load, dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength. Enter the depth, width, and length to calculate the amount of cubic yards needed for your concrete slab. Calculate live load acting on the slab. 5 psf 1/2" Drywall Ceiling = 2.
