Cyclic load testing of three haunched reinforced concrete beam-column assemblies

Finite Element Analysis of Reinforced Concrete Column Under Lateral Load

To serve its purpose a structure must be safe against collapse and serviceable in use. Serviceability requires that deflections be adequately small to keep the cracks within tolerable limits. Although the widely followed ACI Code suggests a detailed method of deflection calculation, it often cannot exactly perceive the actual behavior of a structure. For this purpose, finite element analysis, u...

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...

Cyclic Evolution of Damage and Beam-column Interaction Strength of Concrete-filled Steel Tube Beam-columns

The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...

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

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...
