EVALUATION METHODOLOGY FOR PRECAST CONCRETE DIAPHRAGM CONNECTORS BASED ON STRUCTURAL TESTING
Proper performance of connection details is critical for the effective design and safety of precast concrete building and bridge systems. The paper presents an experimental approach of assessing the strength and deformation capacity of embedded connections used in conventional precast concrete panel system. The approach is applied to in-plane loading on the connectors. A summary of the testing fixtures, testing procedures and data processing methods are provided. In addition, a recommendation is provided for categorizing the connector based on their deformation capability. Three in-plane deformation ranges are identified: low deformation element (LDE), moderate deformation element (MDE) and high deformation element (HDE) to categorize the connections. Lastly, a method for computing the design strength based on the test results is discussed.
