April 2014: Design Deficiencies in Edge Barrier Walls in Parking Structure

Thank you for your excellent article in STRUCTURE magazine on “‘edge barrier walls” in parking structures. We need more of these type practical articles  ̶  this is especially important for young structural engineers. In Figure 1, the #4 standard hook is not developed in a six inch wall  ̶  reference CRSI Reinforcing Bars: Anchorages and Splices. In the past twenty years or so, I have investigated parking structure problems and found most serious structural issues to be related to connections. Thanks again and good luck.
