![]() What if the tabulated loads in the catalog for a single connector just aren’t enough? Use multiple connectors! An important note on using multiple connectors, though: Using four hurricane ties doesn’t always mean you’ll get 4x the load. Alternate seismic and hurricane tie applications. Traditional Linear Interaction Equation Figure 2. I won’t go into too much detail on this topic since it was covered in a recent blog post, but in lieu of the traditional unity equation shown in Figure 1, certain Simpson Strong-Tie connectors (hurricane ties included) are permitted to use the alternative approach outlined in Figure 2. When the connector is resisting lateral loads, its capacity to resist uplift is reduced. It’s also important to consider combined loading if you plan to use the tie to resist both uplift and lateral loads. at each end, don’t select a hurricane tie with a published capacity of less than 600 lb. ![]() If your building’s roof trusses have an uplift of 600 lb. In this post, we’ll outline some of the key elements to consider when selecting a hurricane tie for your project. This assortment of models raises the question, “How do you select the right one?” Simpson Strong-Tie manufactures approximately 20 different models of hurricane ties, not counting twist straps, other clips, or the new fully-threaded SDWC screws often used in the same applications. They are most commonly used to resist uplift forces, but depending on regional design and construction practices, hurricane ties may also resist lateral loads that act in- or out-of-plane in relation to the wall. They play a critical role in a structure’s continuous load path and may be used in a variety of applications, like attaching roof framing members to the supporting wall top plate(s), or tying wall top or bottom plates to the studs. When it comes to wood-frame construction, hurricane ties are among the most commonly specified connectors.
