Continuous Load Path Considerations for Load-Bearing Construction

Modern design and construction practices use structural connectors to form a continuous load path that can enable structures to effectively resist wind and seismic forces as a result of being reinforced from the roof to the foundation.

Simpson Strong-Tie connectors are designed to enable structures to resist the movement, stress and loading that results from natural events such as earthquakes and high- velocity winds. When properly installed our connectors will perform in accordance with the specifications set forth in this section of the website, given the correct fastener is used in the provided holes into the recommended base material.

In cold-formed steel framing, connectors such as holdowns, straps, angles and hurricane ties are often fabricated in the field. Unlike Simpson Strong-Tie connectors, these field-fabricated connectors generally are not designed and tested for ultimate and allowable load capacities, and they typically are not code-listed. Moreover, field-fabricated connectors consume valuable man-hours on the jobsite. And because they typically do not have pre-punched holes, the installer may not be locating the fasteners properly to achieve the intended design load.

Simpson Strong-Tie connectors are the most thoroughly tested and evaluated products in the industry. They are value-engineered for the lowest installed costs at the highest-rated performance levels. Because our connector save the contractor time in the field, when properly specified they provide an easier installation at a lower installed cost. They are also warranted for accuracy of design.

A continuous load transfer path from the trusses to the foundation is depicted above. To achieve full design load values, a qualified Designer should ensure that the correct type and number of fasteners, and proper installation methods are used.
