3.0 Chapter Overview0:57
Compute design tensile strengths of tension members by analyzing nominal strength, net areas, and effective net areas, including staggered holes and connecting plates; cover block shear with examples.
3.1 Introduction4:59
Explore the tension member design process, from calculating the governing load to selecting a steel section from the ASC manual, and review built-up sections and tie plates.
3.2 Nominal Strengths of Tension Members8:28
Learn the nominal strengths of tension members by analyzing yield stress, tensile rupture, and net area with holes. Compare two equations to compute nominal strength and select the smaller value.
3.3 Net Areas5:45

3.13 Example 77:55
Calculate the design tensile strength of a 6 by 6 by 3/8 angled section under yielding and net-section rupture, using one line of four 7/8 in bolts and hole deductions.
3.14 Effective Net Areas (Part III of III)10:10
Discover how to calculate shear lag factors for welded steel members under tension, using longitudinal and transverse welds across cases 1–6 of the effective net area framework.
3.15 Example 84:26
Calculate design tensile strength for a plate-to-plate weld using yielding and rupture, with fy=50 ksi, fu=65 ksi, gross and net areas, and longitudinal welds; the smaller governs.
3.16 Example 95:50
Compute the design tensile strength for an angle welded to a plate on one leg, applying case two shear lag and obtaining 388 kips.
3.17 Connecting Elements for Tension Members3:42
3.18 Example 106:42
Determines the design tensile strength of a two-plate connection for a wide flange by yielding and rupture checks, net area, and the 85% rule.
3.19 Block Shear16:22
Explain block shear in steel joints, identify tension and shear planes, and compute block shear strength using dual conditions, net and gross areas, and the UBS reduction factor.
3.20 Example 1113:21
Determine design tensile strength through block shear calculations for angled sections with holes, welded plates, and wide flange sections. Evaluate net area, shear lag, and bolt considerations for safe design.
3.21 Example 1210:04
Compute the design tensile strength for welded A-36 plates by evaluating yielding, net-section rupture, and block shear, with yielding governing and a design strength of 162 kips.
3.22 Example 1312:34
Calculate the design tensile strength of a w12x30 wide flange with flange holes connected by 7/8 inch bolts, incorporating yielding, rupture, and block shear checks to identify the governing strength.

Description

This course is a continuation of Part 1, which dealt with pretty much the introduction to structural steel design, and design methodologies. Part 2 of the AISC Steel Design Course, will deal with the analysis and design of tension members. ASIC 360-22 has been used as a guide, which is the last spec, available at the time of course creation. This five-hour course dives exceptionally deep into the concepts and practical examples relating to steel tension design.

The following topics will be covered in this part of the course:

1) Introduction to Tension Members

2) Nominal Strength of Tension Members

3) Net Area with one example

4) Effect of Staggered Holes with four examples

5) Effective Net Areas with four examples

6) Connecting Elements for Tension Members with one example

7) Block Shear with three examples

8) Selection of Sections with two examples

9) Built-up Tension Members with one example

10) Rod and Bars with one example

11) Pin-Connected Members

12) Design for Fatigue Loads with one example

At the end of each section, you will face two challenging assignments.

Come and join me in this course, to expand your knowledge of steel tension design.

In the next part of this course, we will discuss the design and analysis of axially compression members!
