Problem 4.39 Design the one-way slab shown in the accompanying figure to support a live load of 10 kN/m2. Do not use the ACI thickness limitation for deflections. Assume concrete weighs 23.5 kN/m. f 28 MPa and = 420 MPa. Use p Pmax: (One ans. 240-mm slab %3D with #25 @ 140-mm main steel) -10m- Width of the slab is 10m WL = 10kN/m2 And draw slab section showing all reinforcements along with the slab

Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.
