Numerical Analysis of Reinforced Concrete Beam-Column Joints without Transverse Reinforcement

Full Scale Reinforced Concrete Beam-Column Joints Strengthened with Steel Reinforced Polymer Systems

This paper presents the results of an experimental campaign performed at the Laboratory of Materials and Structural Testing of the University of Salerno (Italy) in order to investigate the seismic performance of reinforced concrete (RC) beam-column joints strengthened with steel reinforced polymer (SRP) systems. With the aim to represent typical façade frames’ beam-column subassemblies found in...

Seismic Behavior of Beam Column Joints in Reinforced Concrete Moment Resisting Frames

Modified Bouc-Wen model for hysteresis behavior of RC beam-column joints with limited transverse reinforcement

An analytical approach based on modified Bouc-Wen-Baber-Noori model has been proposed in this paper for predicting the hysteresis behavior of reinforced concrete beamcolumn joints with limited transverse reinforcement. The analytical model presented in this research is able to capture the characteristics of non-seismic detailed beam-column joints such as stiffness and strength degradation and p...

Numerical simulation of the shear behaviour of reinforced concrete rectangular beam specimens with or without FRP-strip shear reinforcement

The successful validation of a numerical model is presented that can realistically approximate the shear behaviour of reinforced concrete (R/C) rectangular beams strengthened against shear with externally applied open hoop fibre reinforcing polymer (FRP) strips. For this purpose, the measured load-deformation response of ten (10) full-scale R/C beam specimens is utilised. These specimens were l...

Seismic 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...
