Research focus of this paper are stresses in concrete, reinforcement and tendons, cracks and
deflections of the prestressed girders of “Type A” in order to optimize the span of such girder for the
same amount of tendons and reinforcing steel. Serviceability Limit State (SLS) is a condition in which
construction ceases to meet the specific requirements of serviceability (deflection, crack width). The
large deflections can compromise the functionality and appearance of the structure. Crack widths that
are larger than permitted can cause deterioration of the structure (steel corrosion, leakage of liquid
or gas). Deflections and cracks must be within acceptable limits during the service life of the
industrial halls for their safety and durability.
