均布荷载(Uniformly Distributed Load) 指在结构构件的长度或面积上均匀、连续分布的力。其特点是荷载大小处处相等,方向垂直于作用面(通常为竖向),常用符号 ( q ) 表示,单位为牛顿/米(N/m)或千牛/米(kN/m)。例如,桥梁上的人群荷载、楼板的自重均可简化为均布荷载。
数学表达与简化计算
若均布荷载 ( q ) 作用于长度为 ( L ) 的简支梁,其总荷载值为:
$$
F = q times L
$$
总荷载等效作用于梁的中点,由此可计算支座反力与弯矩。例如,跨中最大弯矩为:
$$
M_{text{max}} = frac{qL}{8}
$$
工程表示方法
在结构设计图中,均布荷载通常用平行箭头带标注 ( q ) 表示(如图1所示),或直接标注荷载值及作用范围。这种简化模型显著提升了结构分析的效率。
典型应用场景
例如,《建筑结构荷载规范》(GB 50009)将住宅楼面活荷载标准值定为 ( 2.0 , text{kN/m} ),设计时按均布荷载考虑。

“Uniformly distributed load”(均布载荷)是工程力学和结构分析中的常见术语,指均匀分布在结构某段长度或面积上的载荷。其核心特征为:载荷强度在作用范围内处处相等,且方向一致。以下是详细解释:
均布载荷通常用符号$q$ 表示,计算公式为: $$ 总载荷 Q = q times L $$ 其中:
均布载荷 | 集中载荷 |
---|---|
分散在较长区域(如梁全长) | 作用在单一点(如悬挂重物) |
计算时需积分或简化等效 | 直接以力的大小参与计算 |
例如,简支梁受均布载荷时,最大弯矩出现在梁的中点,计算公式为: $$ M_{text{max}} = frac{qL}{8} $$ 这一结果常用于梁的截面设计或强度校核。
如果需要更专业的分析(如非均匀载荷或动态载荷),建议参考结构力学教材或工程规范(如 ASCE 7、Eurocode)。
