Bridge Load Capacity Calculator

Formula

The formula to calculate the maximum load capacity of a bridge is:

$LC = \frac{S \cdot A \cdot F}{L}$

Where:

$LC$ is the maximum load capacity (tons)
$S$ is the strength of materials used (tons per square foot)
$A$ is the total area of the bridge (square feet)
$F$ is the safety factor (unitless, typically ranges from 1.5 to 3)
$L$ is the length of the bridge (feet)

What is a Bridge Law?

A Bridge Law is a legal regulation or legislation that governs the construction, maintenance, and safety standards of bridges. It includes guidelines for design, materials used, load capacity, and inspection procedures to ensure the structural integrity and safety of the bridge. These laws are typically enforced by transportation or infrastructure departments within a government. Violations of bridge laws can result in penalties, fines, or legal action.

Example Calculation

Let's assume the following values:

Strength of Materials (S) = 50 tons/sq ft
Total Area of the Bridge (A) = 2000 sq ft
Safety Factor (F) = 2
Length of the Bridge (L) = 100 ft

Using the formula:

$LC = \frac{50 \cdot 2000 \cdot 2}{100} = 2000 \text{ tons}$

The Maximum Load Capacity is 2000 tons.
