WebDetermine the maximum uniform distributed load w0 that can be supported by the reinforced concrete beam if the allowable tensile stress for the steel is 28 ksi and the allowable compressive stress for the concrete is 3 ksi. Assume the concrete can not … Web2.5.1 Allowable Stress Design. Allowable Stress Design (ASD) is also referred to as the service load design or working stress design (WSD). The basic conception (or design philosophy) of this method is that the maximum stress in a structural member is always smaller than a certain allowable stress in bridge working or service conditions.
