Seismic Behavior Analysis on Reinforced Connections of Multibarrel Tube-Confined Concrete Column and Beam Numerical Simulation


Article Preview

Double L-stiffened plate or haunch is used to strengthen the connection to meet the requirement of the code for seismic design of buildings: The principle of strong connection-weak connected member. The two kinds of reinforced connections are simple and easy to construct. Using software ANSYS to research is done on the connection under the monotonic load and low-frequency cyclic load. The results show that: the reinforced connections have high bearing capacity, superior hysteretic performance, and very good ductility; when failure the deformation of the joint region becomes smaller, and the plastic hinge shifts away from the region so as to prevent the brittle failure of the region; the beam has a long yielding plateau, and the bearing capacity decreases not very much after the beam yielding.
