Importance of Nails and Staples

Practical information for residential seismic retrofits

One Bible for seismic retrofitters


ESR-1539, formerly NER 272, governs “Power-driven staples and nails for use in all types of building construction.”

Practical application for good residential seismic retrofits

ESR-1539 lists the earthquake resistance of nails and staples.  It is useful when designing a residential seismic retrofit, no matter what retrofit method you use. This is important not only if you design your own retrofit, but will also give you a sound basis with which you can ask retrofit contractors and engineers questions to see if they know what they should know about residential seismic retrofitting.

ESR-1539 is especially useful  when designing earthquake retrofits for atypical houses that don’t use commonly found nails and staples.  For example, if you want to staple two pieces of wood together to prevent splitting and also want to know if it can resist earthquakes, ESR-1579 will tell you.

Along with the hardware found in the Simpson Strong-Tie Catalog, nails and staples are the most common products used in wood frame seismic retrofits.

Don’t Try This At Home

This website is intended to help clients of Bay Area Retrofit to understand their retrofit plan, and as a resource for retrofit professionals.

IT IS NOT INTENDED AS A GUIDE FOR DIY RETROFITS. Retrofit design is based on many factors. Each house is unique. Bay Area Retrofit does not recommend performing a retrofit without the guidance and supervision of experienced and knowledgeable retrofit professionals, and is not responsible for costly errors, injuries, or earthquake damage that result from such attempts.
