The 24 ft beam shown is laterally braced at the ends and at the centerline of the beam span. The beam supports two concentrated live loads of 15 kips at the / and points. Assume 50 ksi steel and use a calculated value of Cb. You may neglect the beam self-weight. Select the lightest W-shape. As part of your answer indicate the following: Problem 3 (20 points) Member selected W X Cb Mu DMa PL PL 12 ft 6 ft...
1. A simply supported beam is 14-ft long and is braced only at the ends. A concentrated service live load of 55 kips is located at midspan of the beam. Determine whether a W14x53 is adequate for this beam? The steel is A992, use LRFD.
Problem l The beam shown below is laterally braced at D,F and F. The uniform load shown does not include the weight of the beam. Determine whether a W24x 104 ASTM A992 is adequate for bending and shear.

Problem 2 (65%) (see table on page 2 for values of Wu(AB) and W (AC) Two simply supported beams meet at the corner 16 foot tall beam-column "A" shown. Beam AB carries supports a uniformly distributed factored design load W AB)=?? and is 24 feet long. Beam AC carries a uniformly distributed load, W.AC=?? and is 16 feet long. Compute the following if the beams and the beam-column are laterally supported at the ends only in this braced frame. a)...
1. The floor framing plan is shown below. Design the beams B1, B2, and Ba Check the beam weight for each beam. The bay does not repeat. Note The dead load does not include the weight of the beam Select the most economical section for each design to be fully laterally braced. Use A36 steel where Beam B1 frames into it only. Use A992 Grade 50 steel is considered fully braced by the slab it supports. Use A992 Grade 50...
The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...
(Text 6.8-6) The member shown in Figure P6.8-6 is part of a braced frame. The axial load and end moments are based on service loads composed of equal parts dead load and live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity, El, was unreduced. Select a W shape of A992 steel.
The beam shown in Figure has lateral support only at the ends. Both the uniform load and the concentrated load is live load. Use S355 steel and select a HEB shape. The live load deflection must not exceed L/360. Use LRFD. ? 100 kN 30 kN/m 6 m 6 m 12 m
Select the lightest designated W14x section (A992) for the load condition given below assuming the member is fully braced against lateral torsional buckling and no holes: Pu = 400 kips (tension) Mux = 300 kip-ft Muy = 0 kip-ft Make use of AISC-15 Table 6-2 but verify selection using more detailed calculations, tables and beam charts.
1) Select the lightest section that can be used for the beam shown below if lateral bracing is provided only at the ends of the beam. Given loads are service loads (dead load given includes beam dead weight). Use Fy= 50ksi. The point load is applied at midspan. 4) Select the lightest section that can be used for the beam shown below if lateral bracing is provided only at the ends of the beam. Given loads are service loads (dead...
