Engineering Tilt-up: Design provisions born from past experiences

Speaker: John Lawson, PE, SE, Cal Poly, San Luis Obispo

The design of tilt-up concrete wall panels is largely based on past experimental observations, and the design of their anchorage to the roof is largely based on past failure observations. These observations have been pivotal in developing rational design requirements, and often these observations have had surprising outcomes. Without understanding the past, design engineers are at risk of repeating previous failures. Whether designing small or big-box retail or large e-commerce warehouses, designing wood roof systems in the west or steel deck systems in the east, tilt-up construction is very popular throughout the United States, yet is the least understood of common building types. During this SE University session, John Lawson, PE, SE, from Cal Poly, San Luis Obispo, will educate engineers on the current design provisions for tilt-up concrete walls and their proper anchorage, and more importantly, show how these provisions are linked to the past.

Learning Objectives

After participating in this session, the learner will be able to:

  • Recognize past failures and how they impact current design practices.
  • Understand the implementation of current slender wall provisions.
  • Evaluate the wall anchorage forces and their transfer into the diaphragm.
  • Understand anchorage issues for both steel and wood deck roofs.
  • Classify the shear walls for design.
