Where truss members have been cut, shifted or altered in any manner to meet construction needs or for any other reason, additional drawings and additional calculations must be prepared, signed and sealed by the truss designer (a Florida-delegated engineer). Where a girder or truss is subjected to concentrated loads or any unusual loading condition, such conditions must be clearly indicated on the roof framing plans and on the truss design drawings. The intent of the above requirements is to provide all information on framing, connections and bracing on one composite set of plans approved by the architect or engineer of record to aid in the review, approval and field inspections for the portion of the property.Ģ319.17.2.1.2 Trusses shall be designed for wind loads per Chapter 16 (High-Velocity Hurricane Zones), uniformly distributed live, dead and concentrated loads, and such loads shall be indicated on the roof framing plans and the truss design drawings. These marks must remain after the flooring, sheathing and insulation have been installed. Flat and floor trusses must be clearly marked so that they will be installed right side up. Truss design drawings shall indicate the support and minimum bearing of the roof structural system, the permanent cross/lateral bracing, bracing to transfer member buckling forces to the structure and all bracing and anchorage required to resist uplift and lateral forces.ħ. Hip sets shall be detailed in a manner to indicate all connections according to engineering drawings for the attachment of skewed members.Ħ. The connection between trusses shall be detailed in the shop drawings. The size and location of all plates at each joint shall be shown on the truss design drawings.ĥ. A size 8 1/ 2-inches by 11-inches (216 mm by 279 mm) cut sheets showing individual member design shall also be furnished to the architect or engineer of record so that all gravity and uplift loads shown on these cut sheets can be transferred to the primary plans.Ĥ. All details and sections required to show the size and connections of all secondary members will be supplied on the delegated engineering plans and shall show all framing, connections and bracing on one or more primary plans of minimum size 24 inches by 36 inches (610 mm by 914 mm).ģ.
#REPAIR BOTTOM CHORD OF TRUSS PROFESSIONAL#
Where lateral bracing is used, this bracing shall be restrained against lateral movement, in accordance with details provided by the delegated engineer or by the architect or professional engineer of record.
#REPAIR BOTTOM CHORD OF TRUSS SERIES#
This bracing may be in the form of (but not limited) to “T” bracing of an individual member, or lateral bracing of a series of members common to a number of trusses. The contractor shall be responsible for seeing that this bracing is properly installed. The design of this bracing shall be the responsibility of the delegated engineer. This bracing shall be designed for both upward and downward loads and shall be shown on the individual truss drawings (truss engineering usually shown on 8 1/ 2-inch by 11-inch (216 mm by 279 mm) sheets (“A” size drawings). Permanent bracing of individual truss members may be required on certain members of the trusses to prevent the members from buckling in the plane normal to the trusses (buckling in the narrow direction). If reframing is approved, the architect or engineer of record shall resubmit revised framing plans to the building official after receiving updated plans from the delegated engineer showing all adjustments necessary to safely transmit all applied loads to the foundation.Ģ. All shop drawings shall be in conformity with the architect or engineer of record framing plans unless prior written approval is obtained from the architect or engineer of record. The shop drawings shall meet the following requirements:ġ. Such shop drawings shall be submitted to the building official for review and approval. The truss system designer (delegated engineer) shall prepare the truss system shop drawings. 2319.17.2.1.1 Prefabricated wood trusses shall be designed by a registered professional engineer (delegated engineer) and fabricated in accordance with the National Design Standard for Metal Plate Connected Wood Truss Construction of the Truss Plate Institute (TPI).
