Slab torsional strength

WebThe thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure. The minimum thickness can be determined by many factors: • Shear strength of beamless slabs (usually a controlling factor); slab must be thick enough to provide adequate shear strength WebMoment Slab Definition. The moment slab reinforcement shall be designed to resist forces developed at the base of the barrier. The torsion capacity of the moment slab must be equal to or greater than the traffic barrier moment generated by the specified TL impulse load (TL-3, TL-4, TL-5) applied to the top of the barrier.
