2014 TCA Convention

The Design of Tilt-Up Concrete Buildings for Earthquakes: Always a Work in Progress?

John Lawson, PE, SE, Assistant Professor at Cal Poly, San Luis Obispo

 

The current seismic design provisions in the building code for tilt-up buildings are not a result of ever forward thinking, but more of repeated reactions to earthquake events. This “trial and error” approach has at times left the industry with a black eye; yet at this point it is hopeful the building code has flushed out the past seismic vulnerabilities of tilt-up buildings.

Lawson provides an overview of the engineering practices and code provisions in the seismically active western United States as tilt-up construction has matured. Frequently cited as the Achilles heel of tilt-up buildings, anchoring walls to the roof for earthquake loads will be discussed in detail, as well as how the birth of slender wall design occurred in California before spreading across the United States.

Lawson will map out where we have been, where we are, and where we are going.

 

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
