Maximum Deflection Limit for Steel Beam

The maximum deflection limit for a steel beam is an important factor to consider during the design process. The maximum allowable deflection is the amount of bending or sagging that a beam can undergo without causing damage or failure. The maximum deflection limit is determined by several factors, including the span of the beam, the load it will carry, and the material properties of the steel.

Calculation of Maximum Deflection Limit

The maximum deflection limit for a steel beam can be calculated using the following formula:

δmax = L/325

Where:

δmax = maximum allowable deflection (inches)
L = span of the beam (inches)

Explanation of Options

Option A, "Span/180", is not the correct answer because this value would result in a larger maximum deflection limit than the actual limit.

Option B, "Span/200", is also incorrect because it would still result in a larger maximum deflection limit than the actual limit.

Option D, "Span/400", is too conservative and would result in a smaller maximum deflection limit than the actual limit.

Therefore, the correct answer is option C, "Span/325", which accurately represents the maximum deflection limit for a steel beam.

Conclusion

In conclusion, the maximum deflection limit for a steel beam is calculated based on several factors, including the span of the beam, the load it will carry, and the material properties of the steel. Option C, "Span/325", is the correct answer for the maximum deflection limit for a steel beam.
