The catastrophic seismic events have urged the need for effective retrofitting techniques for
the non-seismically designed structures built in the seismic active zone. The design and …

Reinforced concrete (RC) beam-column joints in many old buildings do not have
appropriate seismic detailing that allows them to provide sufficient strength and stiffness in …

Sixteen reinforced concrete beams having the cross-sectional dimensions of 100× 200×
2000 mm and clear span of 1800 mm were cast and tested until failure under a single mid …

Unreinforced masonries are weak against seismic loads which necessitates their retrofitting.
Ferrocement is widely used as it is cheaper than alternative methods of retrofitting. Some …

The purpose of this paper is to evaluate the behavior of vulnerable joints of substandard RC
frames, improved by two different methods, 1-Shear and flexural retrofit of beam–column …

In this study, a method of strengthening polyvinyl chloride (PVC)-carbon fiber reinforced
polymer (CFRP) confined concrete (PCCC) column-reinforced concrete (RC) beam exterior …

Lightweight concrete (LWC) is one of the most important building materials nowadays. Many
research studies were focused on LWC produced using lightweight aggregates. However …

This paper proposes a simple and practical method for retrofitting deficient (non-seismic
detailed) exterior beam-column joints based on fixing steel plates and angles around the …

Recent exploration has focused on repairing and strengthen reinforced concrete (RC)
beams subjected to torsional loading through various techniques. However, limited attention …

Defects in the beam-column connections of old RC frames significantly increase the
vulnerability of exterior connections in an earthquake. One of the methods for improving the …
