Question

ermine the maximum value of service load P that can be carried by this beam usingA RFD considering 1) bending: 2) shear strength and 3) deflection limit of L/360. The load P is 25% dead load and 75% ght. T and at the mid-span point only. Beam section is built-up of A992 steel plates, as shown. Use the User Note in section F2, page 16.1-48 to calculate Lr for this doubly symmetric section with o live load. Disregard the self-wei he beam is braced at the supports rectangular flanges. In this user note h is the clear distance between flanges. PL 14x1 32 A902 14 14 PL 14x1" 28 14*
