この 死荷重計算機 構造の engineering tool used to estimate the weight of permanent structural components in a building or construction project. Dead loads include materials such as slabs, beams, columns, and walls that remain fixed throughout the structure's lifespan. This calculation is essential for designing safe and stable structures, as dead loads affect the overall load-bearing capacity and foundation requirements.
使用することによって 死荷重計算機, engineers and architects can determine the load distribution on different building components and ensure コンプライアンス with safety standards and structural codes.
Formula of Dead Load Calculator
Dead load calculations depend on the type of structural element being considered. The following formulas help determine dead loads for slabs, beams, columns, and walls.
a) Slabs (Uniform Load)
For slabs, the load per unit area is calculated as:
DL (kN/m²) = Material Unit Weight (kN/m³) × Thickness (m)
b) Beams and Columns (Line Load)
For linear structural elements like beams and columns, the dead load is calculated as:
ダウンロード（kN / m) = Material Unit Weight (kN/m³) × Cross-Sectional Area (m²)
c) Walls (Distributed Load)
For walls, considering both thickness and height, the dead load is determined using:
DL (kN/m) = Material Unit Weight (kN/m³) × Thickness (m) × Height (m)
These formulas help calculate the dead load impact on different structural components, ensuring the structure can handle the permanent weight.

Example of Dead Load Calculator
Example 1: Calculating Dead Load for a Concrete Slab
A 強化 コンクリートスラブ には次のプロパティがあります。
- 厚さ = 0.2メートル
- Material Unit Weight = 24 kN/m³
式の使用：
DL (kN/m²) = 24 × 0.2
DL = 4.8 kN/m²
So, the dead load for the concrete slab is 4.8 kN per square meter.
Example 2: Calculating Dead Load for a Brick Wall
A brick masonry wall 寸法は以下のとおりです。
- 厚さ = 0.3メートル
- 高さ = 3メートル
- Material Unit Weight = 19 kN/m³
式の使用：
DL (kN/m) = 19 × 0.3 × 3
DL = 17.1 kN/m
So, the dead load for the brick masonry wall is 17.1 kN per meter.
最も一般的な FAQ
A dead load is the permanent weight of fixed structural elements, including slabs, beams, columns, walls, and fixed fixtures. It does not include temporary or movable loads.
