ACI 551.2R

Abstract

<strong>INTRODUCTION</strong> <br>Tilt-up concrete buildings have been constructed in North America for over 50 years, but it was not until recently that ACI 318 specifically addressed the requirements for design of slender concrete walls. ACI 318 provides a method of analysis in Section 14.8, "Alternative design of slender walls." It covers only the basic requirements for evaluating the effects of vertical and transverse out-of-plane loads. ACI 318, Chapter 10 may also be used to design slender walls, but the requirements are more general and should be applied with discretion. <br>This guide expands on the provisions of Section 14.8, and provides a comprehensive procedure for the design of these important structural elements. This guide also provides design recommendations for various support and load conditions not specifically covered in ACI 318 and includes design guidelines for in-plane shear. <br>Future editions of this guide require further development in the following areas: <br>&#8226;&#160;Seismic design for in-plane forces; <br>&#8226;&#160;Design of tilt-up panel moment frames; <br>&#8226;&#160;Detailed design procedures for panel lifting;&#160;and <br>&#8226;&#160;Panel connection design.
