loading取最大墩宽2.40m，按简支梁梁宽1.0mm作为计算单元 q=Pb=0.05×1000=50N/m
M=0.175×50×26002=42250×103
M42250?103σ===118.7<170MPa 可
W178.0?103?2B、挠度验算
50(2600)4ql4f=0.013=0.013 54EI2.1?10?1780.4?10?2=3.97mm<2400/400mm=6.0mm 可 四、拉杆
采用Φ20圆钢筋，抗拉力为T=3.14cm2×2400kg/cm2=7.54t 拉杆间距：一般为1.0米×1.0米；最大为1.0米×1.5米 T=1.0×1.5×5t/m2=7.5t<[T]
