Design and construction professionals face significant challenges driven by increasing customer demands, rapidly changing material costs, strained supply chains, and the loss of workers going into trades. However, a more urgent issue is that climate change is a real and growing concern. Given that concrete is the most widely used manufactured material in the world, the Portland Cement Association (PCA) has challenged the design and construction industries to address the issue by developing a roadmap to carbon neutrality by 2050. Optimization, avoiding overdesign, designing for performance, and leveraging technology are critical parts of the path. This Seminar focuses on one opportunity to improve environmental outcomes and the competitiveness of concrete as a structural system by using advanced analysis, materials, and methods to design plain concrete in structural ground-supported slabs. Since structural ground-supported slabs are foundations that transmit vertical loads or lateral forces from other portions of a structure to the soil, the provisions of ACI 318 are applicable. These types of slabs are common in ASRS (Automated Storage and Retrieval Systems) with rack-supported roofs.
