钢梁跨度2.4米，要求均布荷载达到4.0kg/m ，使用钢格板G505/30/100承载力能否满足实际要求？

钢格板安全均布荷载[f]= 170000(kN/m^2)

计算强度：qB2σ =-------------- =         40658.8(kN/m^2) <[f]8 N1W

计算强度满足要求                         

当前跨度下，钢格板安全均布荷载 

8 N1W*[f] Pu ≤-------------- =16.72 (kN/m^2)B2                                           

当前跨度下，钢格板安全线荷载                                                              

4N1W*[f]Pl ≤-------------- = 20.07(kN/m)                                           

施加活荷载时，钢格板变形:

5[(q+Wt)L1]B4Dq= -------------- = 5.8(mm)384EI

钢度分母值为：1/[Δ]=B/Dq= 416> 1[Δ]                                                                                           

则钢格板G505/30/100承载力能满足实际要求
