Review of shear stresses for steel beams.
This post is post Number 19s- 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.

A-Solved problem- 2-22 for shear stress parts A, B, and C.
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 problems 2-22, which include Determining the maximum shearing stress for the following sections when the external shear force equals 75 kips for parts A) & B) and C).

The first post is post-20S.
The second post is post 21S.
Solved problem- 10-2 for beam adequacy for shear.
This 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. 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.

This is the link for post 22S: Solved problem 10-2.
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, in which I have 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.
