RE: Holdown Bolt Through the Supported Beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Why would you expect the city to give you strength values??
Look in the Simpson catalogue. They make a pre-bent MSTC strap that is good
for around 4 kip, and is specifically for wall to beam holdown connections.

I thought about using the coil straps but city of LA does not give  
much values to these kind of straps>
