For spans through 60 feet, the bolted diagonal bridging must be installed BEFORE releasing the hoisting lines. FOR SPANS OVER 60 FEET, ALL BRIDGING ROWS MUST BE BOLTED DIAGONAL TYPE.
Bridging for Open Web Steel Joists What is bridging? Bridging is the lateral bracing members, from joist to joist, as provided by the Joist Manufacturer. Bridging braces joists against unanticipated lateral movement during installation and during placement of construction loads and permanently restrains the joist
Bridging is an integral component of the open-web steel joist system that braces the joists against unanticipated horizontal movement during erection, the placing of construction loads, and to permanently restrain the joist chords from out-of-plane or lateral movement when other
based on L/360 allowable deflection, erection stability bridging require-ments and approximate joist weight. It also includes the K-series economy table so the lightest joist for a given load can easily be selected. The ends of K-series joists must extend at least 2 1⁄2” over steel supports (see Figure 2).

2022年2月15日 · Steel joist bridging plays an important role in the overall strength of a joist system. Bridging provides lateral stability during erection and when chords are not fully braced during the application of loads. However, conflicts are common when locating bridging on drawings, in the field, and during retrofits.
STEEL jOIST ERECTION IS pROpER bRIDgINg. A joist may be unstable as soon as the hoisting cable is released, even if other applied construction loads aren’t present. As such, three types of joist bridging play three different roles in creating stabil-ity: erection, construction, and permanent.

Steel bar joists are an engineered product and can only support their required design load if the “system” is designed and installed properly. This requires an Engineer-of-Record (EOR) to be in responsible charge of designing the system, which includes, but not limited to, bridging, proper support conditions, proper connections and ...
