Frequently asked
Why does the load path matter so much?
Lateral force travels like a chain, and the weakest link sets the behaviour of the system. Strong bracing does nothing if force cannot reach it.
Can connection details be copied from another project?
They should not be. Strength changes with thickness, screws and force. Each connection is calculated for its own project.
About this topic
Bracing only works when force reaches it and leaves it for the foundation. In light steel that route runs through screwed connections, and an undefined connection is a broken path.
