Reshoring meant to prevent concrete slab deflection under its own weight, similar to that shown in this photo of another project above, became a point of controversy among the Philadelphia hotel ...

When floor flatness and levelness are measured using F-number technology, timing of measurements is critical because curling of slabs on ground increase with time. The result is decreased F-numbers ...

Cast-in-place reinforced concrete structural members deflect under load. Whatever the cause of the problem, engineers have sometimes tried to control deflection effects by requiring cambered form ...
