Simpson’s Tyrell Gilb Research Laboratory: Where Discovery Meets Development

Why Simpson? > Pioneer in Lateral Systems Development > History of Research and State-of-the-Art Testing > Innovative Product Design > Field and Technical Support > On-Site Training > Product Availability A History of Testing, Innovation and Performance Since Barclay Simpson made his first connector more than 50 years ago, Simpson Strong-Tie has worked with the engineering and building communities to develop products that have significantly improved the structural integrity of homes and buildings. Our team of engineers and product managers continue to look for new ways to solve everyday issues,...

Anchor Tiedown System Introduction The Simpson Strong-Tie Company was founded in Oakland, California and has been manufacturing wood-to-wood and wood-to-concrete connectors since 1956. Since then, Simpson Strong-Tie Company Inc. has grown to be the world’s largest manufacturer of construction connectors. In recent years the company’s growth has included expanding its product offering to include pre-manufactured shearwalls, anchor systems for concrete and masonry and collated fastening systems. The Simpson Strong-Tie Company Inc. “NO EQUAL” program includes: • Quality products value-engineered...

Anchor Tiedown System Important information & general notes WARNING Simpson Strong-Tie Company Inc. structural connectors, anchors, and other products are designed and tested to provide specified design loads. To obtain optimal performance from Simpson Strong-Tie Company Inc. products and achieve maximum allowable design load, the products must be properly installed and used in accordance with the installation instructions and design limits provided by Simpson Strong-Tie Company Inc. To ensure proper installation and use, designers and installers must carefully read the following General Notes,...

Anchor Tiedown System Important information & general notes GENERAL INSTRUCTIONS FOR THE DESIGNER (continued) h. Studs, posts and blocking details shall be specified by the Designer and are not shipped with the Anchor Tiedown System. See tables on pages 35–41 for compression member allowable capacities, design assumptions and general notes. i. In some cases tension anchorage solutions may be designed and provided by Simpson for ATS based on the rod tensile capacity at the first floor. Alternate anchor bolt solutions may be provided by the Designer. Foundation and reinforcement design shall be...

Anchor Tiedown System ATS Selector software ATS Selector Software – design made easier The new ATS Selector software has been created with enhanced design versatility. The program allows engineers and architects to easily create a standard system design or customize the system to meet the specific needs of a project. Easy to use The easy-to-use input screens make it simple to enter all the pertinent job details like project name and address as well as requirements such as number of stories (up to 6), applicable building code, and demand loads. Choose from three base types: concrete, wood and...

Anchor Tiedown System What you can expect from the new anchor tiedown system The Simpson Strong-Tie® Anchor Tiedown System (ATS) has emerged as an innovative solution for light frame multi-story construction. The continuous rod system extends from the foundation to the top of the structure and is restrained (tied off) at each level to provide the load capacity and overturning resistance that’s necessary for multistory buildings—which is especially critical during earthquakes and high wind events. Simpson launched its ATS product line in 2000. Since that time, the company has gathered feedback...

Anchor Tiedown System the new ats Innovative take-up device The stacking of multiple stories can create a significant amount of settling within the structure due to shrinkage and construction loading. The ATS’s new Coupling Take-Up Device (CTUD) helps resolve this issue. The CTUD is an innovative spring-driven rod coupling device, which contracts to compensate for rod movement caused by settling of the structure. Lower installed costs, savings for builders The new Anchor Tiedown System provides several cost advantages. The new CTUD streamlines installation and cuts labor costs by one-third compared...

Anchor Tiedown System Skipped floors Do all floors need to be tied off? There are several continuous tiedown systems available that offer solutions to resist the high overturning forces inherent in multi-story light frame structures. Typically these systems fall into one of two categories: those that call for every floor to be tied off and those where floors are skipped. DRIFT – A skipped-floors system that is properly designed to resist demand loads may not be sufficient to satisfy drift requirements. Test results indicate that skipping floors has the potential to substantially increase inter-story...

Anchor Tiedown System Rod Specifications and Continuous Tiedown Systems As a vital part of any continuous rod tiedown system, it is critical that the rod material have the appropriate performance characteristics. The Strong-Rod™ within the ATS system is made from rod materials chosen from the approved list in section A3 of AISC 360 (Specification for Structural Steel Buildings). This specification was developed as a consensus document to provide uniform design criteria for steel construction. Staying within the AISC specification provides a history of successful usage, advances in the state of...

Anchor Tiedown System Ctud  Coupling Take-Up Device The CTUD is a combination coupler nut and take-up device. It compensates for the slack that develops in the system due to the shrinkage of wood members and settlement caused by dead load and construction loading. It will accommodate up to 1" of movement and is available in standard and reducing sizes for B\,", M\," and 1Z\," diameter Strong-Rod™ or threaded rod. • Design of the CTUD eliminates parts and simplifies installation. • Easy installation saves time, resulting in a lower installed cost. • Witness Holes™ allow for easy inspection to...
