Comparing Sandwich Wall Panel Shear Connector Testing Methodologies, Parker S. Syndergaard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Precast concrete sandwich wall panels (PCSWPs) have been used in the precast industry for decades due to their durability, rapid construction, and thermal efficiency. Shear connectors are used to connect the two wythes of concrete to allow composite action of the system. In order to design concrete sandwich panel systems to act compositely, the engineer must obtain design values from a connector manufacturer, often times making engineers uncomfortable. Shear connectors are typically proprietary, and are required to first have design values validated through destructive testing. The method in which connectors are validated often times varies by each company. This project …
