Seismic and wind events are serious threats to structural integrity and safety. All wood-framed buildings need to be designed to resist shearwall overturning and roof-uplift forces. For one- and two-storey structures, connectors (straps, hurricane ties and holdowns) have been the traditional answer. With the growth in multi-storey wood-framed structures, however, rod systemshave become an increasingly popular load restraint solution.
Multi-storey structures present complicated design challenges. Frequently, the structures have larger windows and entrances, providing less space for traditional restraint systems. For all these reasons, there is increased need for restraint systems. For all these reasons, there is increased need for restraint systems that can meet multi-storey structural demands without sacrificing installation efficiency or cost considerations.
Continuious rod tiedown systems are able to answer these demands by restraining both lateral and uplift loads, while maintaining reasonable costs on material and labor. Instead of using metal connector brackets as in a holdown system, continuous rod tiedown systems consist of a combination of rods, coupler nuts, bearing plates, and shrinkage-compensation devices. These all work together to create a continuous load path to the foundation.
