Serviceability using the Canadian Code

Serviceability using the Canadian Code

Serviceability using the Canadian Code

(OP)
Usually I calculate the deflection of a beam using live load only or dead and live load and compare it with a limit that is a function of the length of the beam over some number (typically L/360 and L/240.) Or if I'm checking the deflection of a column, I only consider wind load when comparing it to the drift limit.

However, looking at an old design brief, I observed several load combinations used for serviceability and I am not sure where these combinations are coming from:

1.0D + 1.0L + 0.5S
1.0D + 1.0S + 0.5L

(The above combs are taking into consideration both snow and live)

And several other load combinations that I will post tomorrow when I am at work

And for wind:

1.0D + 1.0W

(The above is taking into consideration dead load when checking lateral drift)

This could be very trivial, but I best verify and understand this instead of doing something wrong for a very long time.

Thanks
