Bar  Connections Strengthening Existing Steel Joist. Support Warren type truss configuration and incorporated two top chord bars and two bottom chord bars. Some modifications have included welding steel plates, angles, channels, and rounds to the joist chords in an effort to increase the gross section modulus of the joist.

Similarly, welded attachments may not be successful due to difficulties with welding access at the top chord and/or quality concerns associated with field welding. Where this type of modification has been implemented, the end of the steel beam is coped to a depth of 2 1/2 inches and the web is reinforced with steel angles.

The 32-minute video guide on the safe erection of open web steel joists and joists girders was developed jointly with the SteelStrengthening of existing steel joist framing systems—Vulcraft’s field bolted spliced – Steel Bar Joist Connections Masonry

In the event the existing open web steel joists are not capable of safely supporting the new loads, new full-length joists often can not be inserted due to the lack of clearance needed to insert the new joist into the existing cavity.

This match is necessary to ensure that the beam will evenly support the proposed loading without overloading and/or causing a premature failure of the existing adjacent open web steel joists.

The building has a motorcraft and motorcraft accessories showroom on the first floor and a mezzanine level located on the east side of the building.

Steel Bar Joist Connections MasonryAlthough 6 inches of snow would not overload the joists, the concern was that blowing snow could create drifts at the parapets and screen walls that could overload the roof joists at those areas.

Although field-bolted spliced joists will strengthen the structure in a localized area, additional calculations are required by the structural engineer of record to ensure the metal roof deck and support girders are adequate to support the proposed loading.
