An evaluation method for preoast concrete diaphragm connectors based on structural testing

摘要

This paper describes an experimental approach for assessing the stiffness, strength, and deformation capacity of embedded connections in conventional precast concrete floor systems. It summarizes the test fixtures and equipment, testing procedures, and data processing. Connectors are categorized by their deformation capacity using three in-plane deformation ranges: low-deformation element, moderate-deformation element, and high-deformation element. The paper also discusses a method for computing the design strength based on the test results.
