This initial deflection reduces the compressive ultimate strength of the deck panels. In a study that is described, the initial deflection of some 450 deck panels was measured, and the shape and magnitude of the deflection investigated. The compressive ultimate strength of the panels is calculated and its statistical characteristics are examined.

Get PriceExplanation: Compressive strength is defined as the strength of the hardened concrete which gives the measure of the concrete's ability to resist compressive loads. It can be found out by testing standard-sized concrete cubes (15 cm x 15 cm x 15 cm) or cylinders (15 cm diameter and 30 cm height) under Compression Testing Machine after 7 and 28 days taking an average of three samples.
