Reinforced Concrete Beam-Column Joints: An Overlooked Failure Mechanism
by Hitoshi Shiohara
This paper proposes a new set of general and rational concepts useful in identifying and defining the ultimate behavior of two-dimensional reinforced concrete beam-column joints subjected to lateral load. It is based on a model that reflects observations of the crack pattern at failure and its compatible kinematic field overlooked in previous research. The kinematic model, called a nine-parameter model, is combined with nonlinear constitutive re
