Testing That Builds Confidence: SUMO^® FLEX Results Outperform Design Expectations

Peikko recently completed a series of laboratory shear and tension tests on its SUMO® FLEX wall panel base connection system. Designed for transferring tension, in-plane and out-of-plane shear loads between precast wall panels and supporting foundations or slabs, the goal was simple: validate theoretical design strength and confirm failure behavior predicted by AISC 360-22 and ACI 318-19.

The results are clear. SUMO® FLEX consistently performed far above calculated design capacities, delivering controlled, predictable failure modes ...
