For the strain diagram below, c=8, d=20, fy=40,000. What fails first, concrete in compression or steel in tension?

Concrete’s tensile strength is considered in ultimate moment capacity calculations.

What does Hooke’s Law define?

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:
