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.

Hooked anchorages provide additional anchorage when there is insufficient straight length available to develop a bar.

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.

In a pull-out test, a concrete cylinder containing the bar is placed on a stiff plate and a jack is used to push the bar into the cylinder.

LH is a hormone which helps with female ovulation and the production of the hormone estrogen. Which structure is influenced by LH and secretes the female egg during ovulation?
