A floor loading assessment is the evaluation of the concrete subfloor, not the raised floor. However, you should consider the weight of the raised floor in the floor loading formula. Floor Loading Formula. Floor Loading is: (machine weight + (15 lb/ft2 x svc clear) + (10 lb/ft2 x total area)/ total area
Concrete formworks are subjected to various loads and pressure. Concrete formwork loads and pressure calculations are described in this article. Formworks or molds are considerably important for building constrictions by holding fresh concrete mixture at place until it get required strength by which the self weight can be sustained. Ad Free!

Design calculations are done on the basis of a limiting strain that must not be exceeded. It should be noted that in cases of nonlinear deformation behavior, there is a difference between operating, for example, at 80% of the yield strain and operating at 80% of the yield stress. Different values are obtained as depicted in Figure
