Consider an ASTM A992 W 18×50 beam forspan and uniform dead and live loads as shown in Figure 1. Стержень ограничен максимальной номинальной высотой 18 дюймов (45,72 см). The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
