Brick Lintel 1

[jonathanwilkins]

I have a customer who wants to reinforce the brick above a garage door header with 3/16" wire as opposed to a big steel lintel or tying a regular lintel to the garage door header. It's a 16' door w/ approx 30" of brick above it. He's been doing this forever (as long as I've been alive if not longer) just now the building inspector has asked him to have it engineered. I've scoured all the books I have + the internet looking for resources. Any books, papers, direction? One that I can't find is the BIA Tech Notes 17h. Seems to be referenced in a lot of areas but I can't find it. Thanks.

Reinforced brick is possible, BIA Tech notes 17 and 17B. Done some small lintels with exposed brick 3 sides and joint space between for rebar and grout. Shoring and pointing these for appearnce isn't easy.

Not sure joint wire in a bed joint is permitted nor would I count on it as flexural reinforcement.

Wire reinforcement is used in masonry walls and is counted upon as reinforcement, usually for wind loads. The attached file shows an example of three continuous wires, two in the block and one in the brick.

It might be a good idea to cut a shallow channel in alternate bricks in the bottom course to improve the bond.

Talked w/ an engineer for the Brick Industry Association - he gave me this detail which will supposedly be in the 2009 IRC. They tried to get in this version of the code but were a few votes short.
