# Example G.1A W-shape in strong axis shear

The results are generated with SDC Verifier 3.6 and calculated with FEMAP v11.0.0

Determine the available shear strength and adequacy of a W24×62 ASTM A992 beam using the AISC Manual with end shears of 48 kips from dead load and 145 kips from live load.

Solution:

From AISC Manual Table 2-4, the material properties are as follows:

ASTM A992

Fy = 50 ksi

Fu = 65 ksi

From Chapter 2 of ASCE/SEI 7, the required shear strength is:

From AISC Manual Table 3-2, the available shear strength is:

# Example G.1B W-shape in strong axis shear

The available shear strength, which can be easily determined by the tabulated values of the AISC Manual, can be verified by directly applying the provisions of the AISC Specification. Determine the available shear strength for the W-shape in Example G.1A by applying the provisions of the AISC Specification.

Solution:

From AISC Manual Table 1-1, the geometric properties are as follows:

W24×62

d – 23.7 in.

tw = 0.430 in.

Except for very few sections, which are listed in the User Note, AISC Specification Section G2.1(a) is applicable to the I-shaped beams published in the AISC Manual for Fy = 50 ksi.

From AISC Specification Section G2.1a, the available shear strength is:

Example G.1A

From Chapter 2 ASCE/SEI 7, the required shear strength is:

From AISC Manual Table 3-2, the available shear strength is:

Example G.1B

From AISC Specification Section G2.1a, the available shear strength is:

Comparing results of calculation in SDC Verifier and in Example G.1AB we can see that values completely match.

The required shear strength is 289.6 kips.

The available shear strength is 305.73 kips.
