## CE Board Exam- Design and Construction Review Problems

Concrete beam 8meters long and spaced 4m center-to-center are used to support a concrete slab 115 mm thick. The beams have effective depth of 650 mm measured from the slab surface, bw=300mm, and are reinforced for tension only with six 28-mm-diameter bars. The beams are to be analyzed as T-beams. Steel yield strength fy=350MPa and concrete strength fc=21MPa.
