1. What is Maximum Compressive Load on Bracket?

Definition: This calculator determines the highest compressive force that a bracket can withstand when supporting a vessel under wind loads.

Purpose: It helps engineers design appropriate support brackets for vessels and structures exposed to wind forces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{Load} = \frac{4 \times F_{Wind} \times (H - c)}{N \times D_{bc}} + \frac{\Sigma W}{N} \]

Where:

\( P_{Load} \) — Maximum compressive load on bracket (N)
\( F_{Wind} \) — Total wind force acting on vessel (N)
\( H \) — Height of vessel above foundation (mm)
\( c \) — Clearance between vessel bottom and foundation (mm)
\( N \) — Number of support brackets
\( D_{bc} \) — Diameter of anchor bolt circle (mm)
\( \Sigma W \) — Total weight of vessel (N)

Explanation: The formula accounts for both wind-induced moments and the vessel's weight distribution across the brackets.

3. Importance of This Calculation

Details: Proper calculation ensures structural integrity, prevents bracket failure, and maintains vessel stability under wind loads.

4. Using the Calculator

Tips: Enter all required parameters. Note that all dimensional inputs include ±5% tolerance. Number of brackets must be ≥1.

5. Frequently Asked Questions (FAQ)

Q1: What does the ±5% tolerance mean?
A: It accounts for measurement uncertainties and material variations in real-world applications.

Q2: How do I determine the total wind force?
A: Calculate wind pressure (based on wind speed and vessel dimensions) multiplied by the exposed area.

Q3: What's typical clearance (c) value?
A: Typically 100-300mm, but depends on vessel design and foundation requirements.

Q4: How many brackets should I use?
A: Usually 2-8, depending on vessel size and weight. More brackets reduce individual loads.

Q5: Does this include safety factors?
A: No, apply appropriate safety factors (typically 1.5-2.0) to the calculated load for design.
