List of Steel Beam Posts-part 3.
Review of Shear stresses for steel beams.
This is Post number 19S of the Steel Beam Posts for Shear of the steel Beam, in the list of steel Beam posts Part 3, which includes a Review of Shear stresses for steel beams and the relation between horizontal and vertical Shear stress and the stress value of Shear stress based on Shear force and first Moment of Area.

A-Solved problem 2-22 for Shear stress parts A, B, and C.
There are two posts, 20S and 21S, on steel Beam Posts. First, an Introduction to Shear stress for a Rectangle: how can we estimate it? How do you get the first Moment of Area for an I-section and derive the Shear stress equation?
Two posts discuss solved problem 2-22, which includes determining the maximum Shear stress for the following sections when the external Shear force equals 75 kips for parts A), B), and C).
For item C, in solved problem 2-22. For the I-section W12x87, I obtained the relevant Flange depth and web thicknesses from Table 1-1. the width of the flange=12.125″ and its width=0.81″.
The web thickness is 0.515″, and the overall height of the W section is 12.53″. Ix=740.0 inch4.

Solved problem 10-2 for Beam adequacy for Shear.
This post includes a solved problem from Prof. McCormac’s book. Solved problem 10.2: a given steel section W21x55 with Fy =50 ksi. The loads for the Beam are shown in Fig.10.4. It is necessary to check its adequacy in Shear.
The second part discusses the Nominal Shear strength for steel beams based on CM#14—the relation between Nominal Shear and the ratio of hw/tw for different steel grades.

Solved problem 10-2: How do we use Table 3-2 for Shear value?
The first part of the post includes a solved problem from Prof. McCormac’s book. A solved problem 10.2: a given steel section W21x 55 with Fy =50 ksi. The loads for the Beam are shown in Fig. 10.4, where I used Table 3-2 to find the Shear value for the solved problem. 10-2.
The second part discusses the Nominal Shear strength for steel beams based on CM#15.
Check section M12.5×12.40 for Shear and estimate the Nominal Shear strength.
