A truss-type joist comprises a pair of elongated, parallel spaced apart wood chord members which are interconnected together by a web and have fasteners associated therewith to secure the web to the chord members. End portions of the wood chord members extend outwardly beyond said web at at least one of the opposing ends of the joist. A fabricated wooden structural beam insert is located between and interconnected to the outwardly extending end portions of the wood chord members whereby to enable that end of the joist to be cut and shaped at a job site to desired dimensions.
