E702.6-22 - Designing Concrete Structures Concrete Pan and Joist Floor System (PDF)

Pdf Summary

The document is a guide created by ACI Committee E702 on designing a concrete floor system using the pan and joist system. It is an educational resource for ACI University and is intended for professionals, providing a step-by-step design process for creating reinforced concrete floor systems. The guide, based on the 2014 ACI 318 building code Strength Design Method, involves using prefabricated forms with specific dimensions and materials. It includes detailed instructions on determining design loads, dimensions, and reinforcement details required for constructing a concrete floor system.<br /><br />The guide emphasizes the necessity for users to establish appropriate health and safety practices when using the document and to ensure compliance with local laws and regulations, including those by OSHA. ACI does not provide health and safety guidance with this document nor does it take responsibility for condition assessment, structural evaluation, or specification of repair methods.<br /><br />Key aspects of the guide include:<br />1. Calculating slab thickness based on provided design loads and ensuring it's greater than the minimum thickness requirements as per ACI standards.<br />2. Determining reinforcement needs using welded wire reinforcement, taking into account minimum steel area and proper spacing.<br />3. Checking joist dimensions against minimum depth and width specifications to ensure deflection checks are unnecessary.<br />4. Ensuring proper shear and moment capacity checks are performed to validate the design.<br />5. Using ASTM standards for welded wire reinforcement for concrete applications.<br /><br />The document also notes the historical utilization of welded wire reinforcement in concrete applications, particularly in the designing of one-way and two-way slabs. Users are advised on considering all regulatory limitations before applying methodologies and to ensure detailed structural evaluations by experienced engineers.
