2-160 points] A992 steel (F, 50ksi) is used and LRFD method is to be followed. a) Through calculations determine if w14x 38 is compact or not. b) The beam shown below is laterally braced only at the ends. The applied load is a service live load. Through calculations determine if W14x38 is adequate. Note: Shear forces are of no concern. You are not allowed to use the beam design chart included at the end of the exam. 302...
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...

Reading Materials: (1) AISC 360 specifications: Chapter F in AISC Manual Part 16; (2) AISC ASIC Part 3: Flexural Members, and (3) Class notes on beam design. Problem Statement (Consider all possible limit states in beam design). The beam with W27x114, F, = 50 ksi, is loaded with the most critical load combination as shown in Figure 1. Find maximum load P (100% dead load) that can be applied to the...
The beam below is braced laterally only at the reactions and the point of the load. The point load consists of a 34-kip dead and 62-kip live load. Neglect self-weight and you do not need to check serviceability. Find the lightest W-section that will be adequate for the loading. Pp = 34 kip P2 = 62 kip B ус fo 28 ft 18 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.

A W10x60 column with the end conditions and bracing is shown in the figure. Determine the least theoretical bracing (maximum unbraced length) and its location about the y-axis, in order that the y- axis to not control the strength of the column. Also determine the design compressive strength (LRFD) and allowable compressive strength (ASD) for these end conditions (and effective lengths). Use Fy 50 ksi. Also, use the...
