Benefits of Using Puddled HSC with Fibers in Slabs to Transmit HSC Column Loads
Publication: Journal of Structural Engineering
Volume 133, Issue 12
Abstract
The benefits of using “puddled” fiber-reinforced high-strength concrete for the transmission of loads from high-strength columns through slabs is demonstrated. Compression tests were performed on two slab-column specimens and four isolated column specimens (without the surrounding slab). For the tests on the slab-column specimens, vertical slab loading was applied to simulate realistic conditions at the slab-column joint. Predictions using current North American code approaches are compared to the experimental results.
