Microlam Beam Size Calculator

What is a Microlam Beam Size Calculator?

A microlam beam size calculator is a tool used in construction and structural engineering to determine the appropriate size or dimensions of a microlaminated veneer lumber (LVL) beam.

Microlam beams are engineered wood products commonly used to provide structural support in building construction.

Why Use a Microlam Beam Size Calculator?

Using a microlam beam size calculator is essential because it helps ensure that the selected microlam beam can safely support the intended loads and meet building code requirements.

Incorrect beam sizing can result in structural issues, including sagging, deflection, or even structural failure.

How to Use a Microlam Beam Size Calculator:

1. Input the span length, which is the distance between the supports where the microlam beam will be installed.
2. Input the total load that the beam needs to support, including any dead loads (e.g., the weight of the structure) and live loads (e.g., occupants or furnishings).
3. Input the maximum allowable deflection, which is the acceptable amount of vertical sag or bending in the beam under load. This value is often specified in building codes or engineering standards.
4. Click the "Calculate" button to determine the recommended microlam beam size based on the provided inputs.

Example Calculation:

Let's say you have the following parameters:

• Span Length (L): 12 feet
• Total Load (W): 5,000 pounds
• Maximum Allowable Deflection (D): 0.25 inches

Using these values in the provided HTML code:

• Moment of Inertia (I) is calculated as (12^3) / 12 = 144 cubic feet.
• Required Beam Size = (5000 * 12^2) / (4 * 0.25 * 144) ≈ 156.25 inches.

So, the recommended microlam beam size, in this example, is approximately 156.25 inches.

In practice, you would typically round up to the nearest available standard size and consider other factors such as safety margins and local building codes for a more accurate determination of beam size.
