Strengthening of defected beam–column joints using CFRP
This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...
متن کاملFragility Functions for Older Rc Beam-column Joints
A critical step in performance-based seismic design is the prediction and definition of earthquake performance using terms that are meaningful to building owners. Recently, economic impact, defined as the cost of repairing earthquake damage and the building downtime required to complete the repair work, has been adopted as a meaningful measure of building performance. To enable earthquake engin...
متن کاملNeural Networks Assessment of Beam-to-Column Joints
This paper proposes the use of artificial neural networks to predict the flexural resistance and initial stiffness of beam-to-column steel joints using the back propagation supervised learning algorithm. Three types of steel beam-to-column joints were investigated: welded, endplate and bolted with top, seat and double web angles, respectively. The neural networks results proved to be consistent...
متن کاملSelective Upgrade of Beam-column Joints with Composites
Many RC frames built without seismic provisions between the ’50’s and ’70’s need structural upgrade in order to match the minimum requirements of new building codes. Generally, the critical region of the strengthening design is represented by the beam-column connection. The strength hierarchy governs the upgrade requiring to protect the column and the panel so that the formation of a plastic hi...
متن کاملSeismic Upgrade of Beam-Column Joints with FRP Reinforcement
Many opportunities are becoming available for using composite materials to strengthen/upgrade existing reinforced concrete (RC) structures. This paper focuses on a new technique for the seismic upgrade of RC beam-column connections in gravity load-designed (GLD) frames by the application (combined or not) of FRP rods and laminates. The FRP rods provide flexural strengthening, whereas the lay-up...
