Concrete reaches its full compressive strength over time, typically within:

A unit strip of a one-way slab is analyzed like a rectangular beam.

Waffle slabs are also known as grid slabs.

The centroid is always located at the geometric center of a shape.

Calculate the ultimate Moment, Mu of a slab that has a 325 psf dead load that includes the slab weight and a service live load of225 psf. Slab span is 20ft. Final result should be in k/ft

Calculate the maximum bending moment and maximum shear force of a simple supported beam with a uniformly distributed load of 6 k/ft. The beam span is 11ft.

The neutral axis in a beam is the region where:

Factored load for floor slabs with dead and live loads is:

Calculate the weight of a reinforced concrete beam that has a cross section b=13″and h=24″. Span length is 16ft

Calculate the nominal moment, Mn for a beam that has b=13″, d=26″, As is 4#8, F’c=4,000 psi and Fy=60,000psi.
