Question
The semi-compact section of a laterally unsupported steel beam has an elastic section modulus, plastic section modulus and design bending compressive stress of , and , respectively. The design flexural capacity (expressed in kNm) of the section is _________
Correct answer
99.9 to 100.1
Solution
For a semi-compact section, the design flexural capacity () is determined by the elastic section modulus () and the design bending compressive stress ().Given data:
The design flexural capacity is given by the formula:Substituting the values:To express the capacity in kNm:Thus, the design flexural capacity of the section is .
- Elastic section modulus,
- Plastic section modulus, (Note: For semi-compact sections, the capacity is governed by the elastic section modulus rather than the plastic section modulus )
- Design bending compressive stress,
The design flexural capacity is given by the formula:Substituting the values:To express the capacity in kNm:Thus, the design flexural capacity of the section is .
