Tilt-Up Concrete Association Seeks Participation In Regional Detail Study

Español | Translation Sponsored by TCA

In an effort to better understand the myriad approaches to common tilt-up construction details (which vary from region to region), the Tilt-Up Concrete Association is calling on member architects, engineers and contractors to participate in a new study. The study, spearheaded by TCA’s new young professionals’ collaborative, TILT (Tilt-Up Industry Leaders of Tomorrow), will be organized around five typical details.

  • Roof Structure to Panel: These connections transmit gravity; wind uplift; out-of-plane wind and seismic; in-plane wind and seismic forces.
  • Supported Floor Structure to Panel: These connections transmit gravity, out-of-plane wind and seismic forces, thermal bowing, in-plane wind and seismic forces.
  • Panel to Slab on Grade: These connections transmit out-of-plane wind and seismic forces, thermal bowing, lateral earth pressure, in-plane wind and seismic forces.
  • Panel to Footing: These connections transmit out-of-plane wind and seismic forces, in-plane wind and seismic forces, and uplift due to overturning.
  • Panel to Panel: These connections transmit in-plane wind and seismic forces to resist overturning and differential bowing.

“As part of the new TILT group, we are following through on some established directives to help grow and educate membership of the TCA through an expansion of the TCA’s resources,” said Chad Marshall, co-chair of TILT’s Delivery Category of Engagement. “These directives were established during the TILT kick-off event during World of Concrete in 2019 and have developed through meetings and collaborations over the past few months. We, as part of TILT, are in need of members’ help to grow and see this initiative come to life.”

“The focus of TILT’s Delivery Category of Engagement is to unify the method by which design information for tilt-up construction is passed from the design team to the construction team,” said Dylan James, co-chair. “This study is a first step in understanding a potential information gap.”

Over the course of the two-year study, the group will focus on the detail types listed above, one at a time. With each type, they will perform the following process:

  • Collect representative examples from tilt-up engineers, architects, and contractors from across the United States and Canada.
  • Model each submitted detail using building information modeling, applying design standards that allow for easy comparison.
  • Study differences and similarities between details and consider environmental, geographic, and regulatory explanations for variations.
  • Publish findings and recommendations for the good of the industry.
  • Add TCA recommended details to online detail library.

With this announcement, the TCA formally requests submittals of non-proprietary panel to foundation details. Details must be submitted by December 20, 2019 to be included in the study and can be communicated by PDF, or formatted for Revit or AutoCAD, and sent to tilt@tilt-up.org. Authors of all details will remain anonymous in study and publication.

Questions related to this study can be answered by the TCA’s director for technical and regulatory affairs, Jim Baty, FACI, FTCA at jbaty@tilt-up.org or 319-895-6911.
