Seismic performance of two full size reinforced concrete beam-column joint units

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

Seismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...

non-linear seismic behavior of concrete beam - column connections

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

Performance-based Optimization of Strut-and-tie Models in Reinforced Concrete Beam-column Connections

This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced concrete beam-column connections. Developing strut-and-tie models in reinforced concrete beam-column connections is treated as a topology optimizatio...
