LVL (Engineered) Beam Span Tables and Charts for Ontario, Canada

====================================================================================

The use of Engineered/Laminated Veneer Lumber (E-LVL or simply LVL) beams has become increasingly popular in modern construction due to their strength-to-weight ratio, resistance to warping and shrinkage, as well as fire-resistance properties. However, before selecting the appropriate beam size for your project, it is crucial to consult with a licensed engineer who can provide you with specific span tables based on local building codes and load conditions.

In this article, we will focus specifically on LVL beam span tables for Ontario, Canada, under the current 2012 version of the Ontario Building Code (OBC). These tables are intended as a general guide only and should not be used in place of professional engineering judgment or consultation with local building authorities.

Types of Beam Span Tables

-------------------------

There are several types of LVL beam span tables available depending on various factors such as:

1. Type of load: Uniformly distributed (UDL) loads, such as dead weight; concentrated loads, like point loads from beams and rafters; or combinations thereof.

2. Beam configuration: Simple spans (span-to-depth ratio = 3-10), continuous spans (moment-resisting connections at supports).

3. Material properties: Grade of LVL used.

Example Span Tables

----------------

Below are two examples of simple span tables for a typical residential framing application:

### Table 1 - Douglas Fir-Larch No.2 E-Grade, Tongue-and-Groove

| Beam Size (in) | Joist Spacing (oc in) |

| --- | --- |

| 3/4 x 5-1/2 | 16'0' @ 24' O.C. |

| 1-1/8 x 7-1/2 | 19'-6'@ 24' o.c. |

### Table 2 - Spruce-Pine-Fir No.2 E-Green, Tongue-and-Splined

| Beam Size (in) | Joist Spacing (oc in) |

| --- | --- |

| 3/4 x 5-1/2 | 15'-0'@24' o.c.|

| 1-1/8 x 7-1/2 | 17'6'@24'o.c.|

Important Notes

----------------

* Span tables are based on minimum requirements of the OBC and local jurisdictions may have more stringent regulations.

* Actual span values can be reduced due to factors such as:

+ Lateral loads (wind, seismic).

- Eccentricity of applied forces from connections or framing details not accounted for in these tables.

-------

In conclusion, when designing with Engineered/Laminated Veneer Lumber beams under Ontario Building Code provisions, it is essential to consult reputable manufacturers' span tables and/or retain the services of a licensed engineer experienced in structural analysis. Failure to do so may result in costly repairs or even catastrophic failure of structures due to overloading beyond their intended capacity.

LVL Beam Span Table - Final Thoughts

--------------------------------

In conclusion, while this article has provided an overview of the factors that influence LVL beam span tables under Ontario building code requirements, it is crucial to consult with a licensed engineer or structural professional for specific design recommendations tailored to your particular project needs.
