平面移动式立体车库运载系统载荷谱编制与应用

open access: yesJianzhu Gangjiegou Jinzhan
平面移动式立体车库容量大、形式多样,对车位分配的要求更高,载荷形式更多样。因此在研究立体车库的载荷谱时,以平面移动式立体车库为代表对其进行研究,运用概率统计方法,基于车辆存取策略建立了适用于立体停车结构的交变载荷谱;进一步采用四点雨流计数法对载荷谱进行统计和边缘分布拟合,结果表明:载荷均值服从均值为9.876,标准差为0.493的正态分布;幅值服从形状参数为1.603,尺度参数为2.048的双参数winbull分布。通过参数外推得到整个生命周期的荷载频次,建立了对应的8级二维载荷谱和一维载荷谱 ...
