Aisc Steel Manual Shapes With 4
Is anywhere in the CERM showing the self-weight and other properties of W??.?? W12.72) Steel? What does it mean?I know the questions are fundamental and stupid, but am really struggling with this while learning myself. Also, I don't want to bring the AISC Steel Construction Manual as a Transportation exam taker.Please advise. Thanks!SammySammy,In my old 10th edition CERM, on page 58-2 there is a section titled 'Structural Shapes' and it gives an example of a W 30 x 132 designation and states that it 'refers to a W-shape with an overall depth of approximately 30 in that weighs 132 lbf/ft.' Does that answer your question?Also, please note, no standards at all, for any of the 5 AM disciplines, should be required.

Learning how to efficiently use the Steel Manual (AISC Steel Construction Manual 14th Edition) is very important in steel design. Below are some helpful AISC tables/sections to know for the PE/SE exam, college exams, or everyday engineering practice.Table 2-4 Applicable ASTM Specifications for Various Structural Shapes: This table gives the preferred material (i.e. A992 for wide flange, A36 for angles, etc) to use for each structural shape.
You can also go here to to find the ultimate stress and yield stress for each material type. You should know all of this information by heart eventually, but it’s good to know where this information is in case you forget.Table 3-2 W-Shapes Selection by Z: Great table for beam design. This table helps you figure out what beam size to use after you figure out what Z (plastic section modulus) needs to be. For each group, the bold shape is the most efficient design.
Remember also that Lp and Lr are shown in this table for each shape so don’t waste time calculating these values on exams if you are not asked to show your work. This table also has both shear and moment capacity values.Table 3-23 Shears, Moments and Deflections: This table is not only important and helpful for steel design but for any structural design in general.
This is a great place to figure out the shear, moment, and deflection for many different beam situations. Don’t waste time figuring out the shear and bending diagram if you don’t have to on tests. Remember also that if there’s a case where you can’t find the answer in these tables, you can always use superposition and add/subtract the values on each table to get what you need.Table 4-22 Available Critical Stress for Compression Members: This is by far my favorite table for column design. This table will save you a lot of time on exam questions of compression members. Basically you just need to calculate KL/r for your member and you can figure out the capacity if you know the member area! This table works for any member shape and sizes, including built-up members.
The only limitation is that the member yielding capacity has to be 35 ksi, 36 ksi, 42 ksi, 46 ksi, or 50 ksi. When you have a compression member question, this should be your first go to table before going through all the equations.Table 7-1 and 7-2 Available Shear and Tensile Strength of Bolts: These two tables give shear and tensile capacities for commonly used bolts that are attaching two steel members together.Table 7-17 Threading Dimensions for High-Strength and Non-High-Strength Bolts: This table gives the different areas (gross bolt area, minimum root area, and net tensile area) for different bolt sizes. Basically, gross bolt area for the bolt is the same as the area for the rebar, so you can look up the rebar area here if you forget what they are (you can of course also calculate this by hand).
The other two areas are sometimes used in steel design equations and this is the table to look at for those values.Table 8-2 Prequalified Welded Joints: Excellent table that provides you with a quick summary of all the welding symbols/call-outs and what they mean. It also shows you how to correctly call out the welding symbol on a design drawing. If you are a young structural engineer and are drawing up structural details, this is a great place to make sure that you are calling out information correctly and look up what certain welding symbol mean if you are familiar with it.Base Plate Design (page 14-5): Have you wondered how you can easily design a base plate for a column? Wonder no more, because this page gives you an easy chug-and-plug equation to do this design in minutes. Pretty handy!Table B4.1b Width-to-Thickness Ratios Compression Elements Members Subject to Flexure (in Specifications): This is the place to find the equations to determine if a section compact or non-compact for bending (important first step in beam design).Section E3 of Specification Chapter E (page 16.1-33): If you can’t design the column using Table 4-22, this page shows the equations for compression design.Table User Note F1.1 Selection Table for the Application of Chapter F Sections (page 16.1-45): Great table to figure out what limit states to check for in beam design. The relevant specs sections where the equations are located for the design is also shown on the table.Weld Limitations (pages 16.1-109 to 16.1-111): The tables and information shown on the page call out some importation information for max/min sizes for different type of welds. Make sure you follow these requirements for your design.Table J3.3 Nominal Hole Dimensions (page 16.1-121): This table gives the design hole dimension for standard, oversize, short-slotted, and long-slotted bolts.Table 17-27 Properties of Geometric Sections (pages 17-36 to 17-42): This is a nice table to figure out A, c, I, S, r, and Z for some common shapes.Are there other tables or information in the Steel Manual that you think are uber useful?
