Industrial Flooring

The document provides input data and characteristics for analyzing the flooring of two industrial buildings. For the first building, the floor thickness of 150mm is specified, along with other details like width, load, concrete strengths, modulus, and calculated ultimate moment resistance of 13,645 kN-m. For the second building, the floor thickness is increased to 190mm and other parameters are given, with an ultimate moment resistance of 19,704 kN-m. It is noted that for the second building, the increased floor thickness is sufficient.
