Study of Reinforced Concrete Beam-Column Joints Under Uniaxial and Biaxial Loading

Three reinforced concrete beam-column joints were tested under the U.S.-New Zealand-Japan-China Cooperative Project on Design of Reinforced Concrete Beam- Column Joints and are described in detail. The specimens were tested under bi- directional loading. All three included a floor slab. The test results were evaluated using data from other programs to critically examine current design guidelines. Using a larger data base, it was possible to propose some modifications to existing design provisions.
