A rectangular beam has a cross section of b = 14 in., h = 28 in., and d = 25.5 in. It is reinforced with five No. 5 Grade 60 bars. The concrete strength is 5,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the modulus of rupture of the concrete, fr.

In order for a reinforced concrete beam to function properly (concrete resisting compression, steel resisting tension), a bond must exist between the concrete and the reinforcement.

The Attendance assignment is the syllabus quiz which is due on January 14th at Noon; while the other assignments for week 1 are due on January 14th at 11:59 p.m. 

Failure of a hooked anchorage rarely involves crushing of the concrete inside the hook.

There are no scheduled make-up classes or allowance to attend another section for missed on-snow sessions. There are no exceptions for any reason, except for isolation/quarantine due to COVID.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 18 in. and No. 3 stirrups. This beam has four No. 7 bars as longitudinal reinforcement. The clear cover is 1.8 in.

The hardest way to test the bond strength of bars in a laboratory is by the pull-out test.

When the steel ratio, ρw, is small, flexural cracks extend _______ into the beam and open _______ than would be the case with large values of ρw.
