Consequently when calculating prestress losses of prestressed concrete member it is appropriate to assess linearly variable stress distribution along the anchorage zone.
Influence of stress distribution at anchorage zone of prestressed concrete member
During calculation of prestress loss of pretensioned reinforcement, assumption could be made that stresses along the reinforcement are constant or their distribution are linearly variable at the anchorage zone, but are constant beyond the anchorage zone.
Research shows that position of reinforcement at the anchorage zone is mostly influenced by prestressing force and bending moment induced by external effects.
At the anchorage zone rational eccentricity value of pretensioned reinforcement at transfer and service stages is with opposite sign.
Analysis of rational position of pretensioned reinforcement at the anchorage zone was performed by investigating 600 x 400 mm cross-section beam.
These immediately reportable falls--"accidents"--as defined by MSHA, impeded passage or ventilation, caused injury or death, or occurred above the anchorage zone of roof bolts, in turn, these "accidents" triggered MSHA closure order authority under Section 103(k) of the Mine Act.
This power grab resulted in expanded closure for even a non-reportable roof fall, which did not cause Injury, was not above the anchorage zone, and did not impede passage or ventilation.
Most ships stay in the anchorage zone
for about 10 days before heading somewhere else.
One of the cables also needed to undergo water leakage or dunk testing after completion of the fatigue cycling to prove the water tightness of the anchorage zone.
8-foot) head of red-dye solution on an anchorage zone of the 119-strand cable after it had gone through the fatigue testing cycles.
