均布荷載(Uniformly Distributed Load) 指在結構構件的長度或面積上均勻、連續分布的力。其特點是荷載大小處處相等,方向垂直于作用面(通常為豎向),常用符號 ( q ) 表示,單位為牛頓/米(N/m)或千牛/米(kN/m)。例如,橋梁上的人群荷載、樓闆的自重均可簡化為均布荷載。
數學表達與簡化計算
若均布荷載 ( q ) 作用于長度為 ( L ) 的簡支梁,其總荷載值為:
$$
F = q times L
$$
總荷載等效作用于梁的中點,由此可計算支座反力與彎矩。例如,跨中最大彎矩為:
$$
M_{text{max}} = frac{qL}{8}
$$
工程表示方法
在結構設計圖中,均布荷載通常用平行箭頭帶标注 ( q ) 表示(如圖1所示),或直接标注荷載值及作用範圍。這種簡化模型顯著提升了結構分析的效率。
典型應用場景
例如,《建築結構荷載規範》(GB 50009)将住宅樓面活荷載标準值定為 ( 2.0 , text{kN/m} ),設計時按均布荷載考慮。

“Uniformly distributed load”(均布載荷)是工程力學和結構分析中的常見術語,指均勻分布在結構某段長度或面積上的載荷。其核心特征為:載荷強度在作用範圍内處處相等,且方向一緻。以下是詳細解釋:
均布載荷通常用符號$q$ 表示,計算公式為: $$ 總載荷 Q = q times L $$ 其中:
均布載荷 | 集中載荷 |
---|---|
分散在較長區域(如梁全長) | 作用在單一點(如懸挂重物) |
計算時需積分或簡化等效 | 直接以力的大小參與計算 |
例如,簡支梁受均布載荷時,最大彎矩出現在梁的中點,計算公式為: $$ M_{text{max}} = frac{qL}{8} $$ 這一結果常用于梁的截面設計或強度校核。
如果需要更專業的分析(如非均勻載荷或動态載荷),建議參考結構力學教材或工程規範(如 ASCE 7、Eurocode)。
