Question
The flooring of a warehouse is made up of double-tee joints (DT) as shown. The joists are simply supported on a span of 7.5 m and are pre tensioned with one tendon in each stem with an initial force of 745 kN each, located at 75 mm above the bottom fiber. loss of stress at service load is 18%. a=2.4 m 88 NA 192 267 75 mm Load imposed on the joists are: (See loadings) 10 kN/m A 7.5 m
Transcribed Image Text:The flooring of a warehouse is made up of double-tee joints (DT) as shown.

Properties of DT: • A = 200,000 mm? • 1 = 1880 x 106 mm4 • Yt = 88 mm • Yb = 267 mm • a = 2.4 m. Compute the stress in MPa at the bottom fibers of the DT at mid-span due to the initial pre stressing force alone.
