Which of the following expression for reduced plastic moment capacity is correct? |
| A. | M<sub>fr</sub> = 0.25b<sub>f</sub>t<sub>f</sub><sup>2</sup>f<sub>yf</sub> {1-[N<sub>f</sub>/( b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub>/γ<sub>m0</sub>)<sup>2</sup>]} |
| B. | M<sub>fr</sub> = b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub> {1-[N<sub>f</sub>/( b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub>/γ<sub>m0</sub>)]} |
| C. | M<sub>fr</sub> = 0.25b<sub>f</sub>t<sub>f</sub> {1+[N<sub>f</sub>/( b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub>/γ<sub>m0</sub>)]} |
| D. | M<sub>fr</sub> = 0.25b<sub>f</sub> {1+[N<sub>f</sub>( b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub>γ<sub>m0</sub>)<sup>2</sup>]} |
| Answer» B. M<sub>fr</sub> = b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub> {1-[N<sub>f</sub>/( b<sub>f</sub>t<sub>f</sub>f<sub>yf</sub>/‚âà√≠‚Äö√¢‚Ä¢<sub>m0</sub>)]} | |
