Hurricane ties are special connectors used in building houses. They make buildings more resistant to the effects of high winds, especially in areas prone to natural disasters. 2022 TIE-DOWN ROPINGsponsored by Boot Barn Name Winnings Time 169 Cooper Martin 135 Ryan Jarrett 207 Michael Otero 309 Marty Yates 361 Macon Murphy 155 Sherman J Lasker 122 Hunter. Roof and rafter hurricane ties, also called hurricane straps or strips, are galvanized or low-carbon steel connectors used to strengthen wood and metal-framed roofs. We provide world class service and premium seating. Held fine until we tore it off for a second story addition. Rafter Z Rodeo tickets from Front Row will make your live entertainment experience magical. I jacked up the roof over a couple weeks, nailed the out of the rafter/rafter tie lap, and created a truss system with plywood gussets. I talked to my engineer and learned that the connection of the rafter ties to the rafters where they lap was very important. A rafter tie is a tension tie in the lower third of opposing gable rafters that is intended to resist the outward thrust of the rafter under a load. That wasn't enough and over time that nailed joint began to fail and the ridge sagged, the walls moved and the fascia bowed under the stress. Rafter tie connections shall be based on the equivalent rafter spacing in Table 2308.10.4.1. It forms part of a continuous load path to resist. Rafter ties shall be spaced not more than 4 feet (1219 mm) o.c. They were probably enough to keep the rafters in place, the ridge board from sagging and the walls from splaying outward but the framer only used a couple or 3 16d's at the lap with the rafters. A rafter tie aka hurricane tie, provides a direct connection between the roof rafter and the wall framing. My current house had a concrete tile roof with 2 x 6 rafter ties every 4 ft. It is designed to help resist uplift forces. Always use the metal straps over the ridge. The HS24 saddle rafter tie is a wind and seismic tie for trusses and rafters. Rafter tie sizing Rafter ties should be at least 2 x 4 inches (51 mm × 102 mm). I've installed engineer designed collar ties with no rafter ties or ceiling joists but they were engineered carefully and installed properly. They might also reduce the deflection on very steeply pitched and undersized rafters in an existing structure. The extent of such design need only demonstrate compliance of the nonconventional elements with other applicable provisions of this code and shall be compatible with the performance of the conventionally framed system.The author neglects to consider the main purpose of the ties, which is to keep the rafter tops spreading during wind uplift, but this is done much more cheaply through metal straps. When a building of otherwise conventional construction contains structural elements or systems not described in Section 2308, these elements or systems shall be designed in accordance with accepted engineering practice and the provisions of this code. The top plate is the bottom of one rafter and the top of another. In many cases, ceiling joists are installed parallel to the rafters will be utilized as rafter ties. When a building of otherwise conventional construction contains structural elements exceeding the limits of Section 2308.2, these elements and the supporting load path shall be designed in accordance with accepted engineering practice and the provisions of this code.Ģ308.4.2 Structural elements or systems not described herein. A rafter tie is a tension tie in the lower third of opposing gable rafters intended to resist the outward thrust of the rafter under a load. Figure 2: Illustration of Roof with Rafter Tie. Figure 2 is an illustration of a roof constructed using rafter ties. Where ceiling joists or rafter ties are not provided at the top of the rafter support walls, the ridge formed by these rafters shall also be supported by a girder conforming to Section 2308.4.Ĭombining of engineered elements or systems and conventionally specified elements or systems is permitted subject to the following limits:Ģ308.4.1 Elements exceeding limitations of conventional construction. Rafter Tie A tension tie in the lower third of opposing gable rafters that is intended to resist the outward thrust of the rafter under load.
