Is a truss the same as a joist?
While much different in design and function, joists and trusses are often used together in construction projects. While joists support the weight of floors and ceilings, trusses have a wide variety of applications, including supporting roofs and in bridge design.
How do you bridge a joist?
Nail bridging on all joists Start by making sure the original bridging is tightly fastened; add nails or screws if necessary. Then measure the span of the joists (the distance between walls or beams that support the joists). Divide the span by three and add rows of bridging at both of the one-third points.

Can a bar joist support a design load?
Or Text Us! Disclaimer: Bar joists are an engineered product and can only support their required design load if the “system” is designed and installed properly. The Engineer-of-Record (EOR) is responsible of designing this system that includes but not limited to bridging, supports, connections, anchors and specific design loads.
