Nominal flexural strength of the given welded shape.
Answer to Problem 10.4.1P
Explanation of Solution
Given information:
Web thickness
Depth of web from inside face of flange to inside face of flange
Thickness of flange
Area of flange
Calculation:
Web width to thickness ratio given by,
Determine web is slender or not.
Now,
From the above equation web is non slender.
Calculate the elastic section modulus by using the formula,
Calculate
Maximum distance is calculated by using the formula,
Elastic section modulus about the axis
Tension in flange strength is given by,
From AISC table B4-1b than the required slenderness parameters
Here
To calculate the plate girder strength reduction factor values
From AISC Equation
From AISC Equation
Conclusion:
Therefore, the nominal flexural strength for the given welded plate is
