wsdot.wa.gov2. Prestressed Concrete Girders. The nominal 28-day concrete compressive strength (ƒ' c) is 7.0 ksi. Where higher strengths would eliminate a line of girders, a maximum of 10.0 ksi can be specified. Slab girders should be limited to 8.0 ksi. The nominal concrete compressive strength at release (ƒ' ci) is 6.0 ksi. Where

Standard Steel Joists and Joist Girders
www.newmill.comconnection to the overlying concrete slab using field applied shear studs, such that when the decking is filled with concrete, the shear studs become embedded in the hardened concrete and a unified load bearing system is created that deflects as a single unit. Composite steel joist design is an example of Load and Resistance Factor Design (LRFD).
Cracks and Crack Control in Concrete Structures - PCI
www.pci.orgConcrete can crack due to a number of causes. Some of the most significant causes are discussed in detail. Tensile Strength of Concrete The tensile strength of concrete is a widely scattering quantity. Cracking oc-curs when tensile stresses exceed the tensile strength of concrete. Therefore, to control concrete cracking, the tensile
