Checking T-Brace Capacity on Wood Truss Webs

摘要

Web bracing may be essential in order for some trusses to carry their design loads.A lateral brace decreases the effective buckling length of the web member and thus increases web load capacity.With one lateral brace,a compression member is able to carry up to four times its normal load;when two lateral braces are used,the member may carry a load up to nine times greater.
