Abstract:
Based on the needs of the construction industry and in view of the lack of test data regarding the performance of dowels across concrete joints, Danley has carried out research and full scale testing of different dowels embedded in concrete slabs. Concrete test panels measuring 1000mm square x varying thicknesses were manufactured to simulate slabs containing different dowel systems. The panels were tested to ultimate failure at the Concrete Laboratory of Queensland University of Technology. Test data was collected on the load displacement behaviour of samples which provided valuable information regarding the structural performance of different dowel types. This paper presents the results from the test data and endeavours to establish a practical design procedure for plate dowel joints. This design procedure is based on the results obtained and utilises established design procedures (ie. Cement & Concrete Association of Australia – T48) and recent works by Tony Davis and Andrew McDonald.
