Problem #3 (25 points) A simply supported, W12x65 beam (A572 Gr. 55 - Fy- 55 ksi; Fu 70 ksi) is subjected to concentrated loads at third points as shown below. The beam is laterally supported at the ends and at third points (i.e., at each concentrated load). Considering x-axis flexural capacity only, what is the maximum factored load, Pu which can be applied? Assume that the controlling load combination is 1.2D 1.6L P Pu

Problem 1 (100 pts) Select the lightest W24 beam section with Fy = 50 ksi using LRFD for the following span and loading. The unbraced length of the compression flange is 30 ft (Lb = 30'). Consider Cb > 1. The given dead load does not include beam weight. Verify that the selected beam has adequate shear strength. Maximum allowable deflection due to live load is L720. Maximum allowable deflection due to total load is L/360. WD = 1.2 k/ft...

For the continuous beam shown, compute the support reactions using the method of consistent deformations by taking the reaction at support B as redundant. Also, draw the shear and bending moment diagrams. The beam is subjected to a 20 kips concentrated load at the middle of the left span plus a 1.5 inch settlement of support B. Use deflection formulas to determine deflections at B. Assume E-29000 ksi and I-750 in...

A timber [E = 1,800 ksi] beam is loaded and supported
as shown. The cross section of the timber beam is b = 4
in. wide and h = 7 in. deep. The beam is supported at
B by a 0.875-in.-diameter aluminum [E = 10,500

to the beam. After a distributed load of w = 610 lb/ft is
applied to the beam, determine

beam (ignore any torsional effects). Assume d = 41.5 in., ƒc’ =
4,000 psi, and ƒy = 60,000 psi.
