Connecting Precast/Tilt-up to meet High In-plane Shear Load

Often working with concrete (Tilt-up or precast) wall panels, contract drawings require large in-plane shear loads, due to earthquake or wind, to be resisted by these walls. It is also not uncommon to see additional requirements of zero or no uplift on supporting foundations. However, the specified magnitude typically exceeds what a single wall panel can resist on its own, including additional dead loads besides self-weight.

Therefore, individual Walls need to be rigidly connected ('stitched') at their edges to act as a longer wail to resist specified lateral load wiTtir project specifications. This course presents an approach to analysis and design where multiple concrete wall panels are interconnected at edges to resist lateral loads. The course material is presented with the aid of a worked example. The example uses US-customary units however, SI equivalents are also included, where feasible to aid students more familiar with the SI system of units.
