Sustainability necessitates the protection of infrastructure from any kind of deterioration over
the life cycle of the asset. Deterioration in the capacity of reinforced concrete (RC) …

Beam-column assemblies of many existing reinforced concrete (RC) buildings are typically
designed and built before the development of the current seismic codes; that may …

Extensive research efforts over the last decades have focused on the rehabilitation of
vulnerable reinforced concrete (RC) beam to column moment resisting connections. Shear …

Exterior beam-column joints are the most vulnerable part of substandard reinforced concrete
(RC) buildings and are often the first to be damaged during earthquakes. This article …

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 …

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 …

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 …

The performance of moment frames in concrete structures is influenced by the behavior of
beam-column joints. Experience in past earthquakes has shown that beam-column joints …

A review of past earthquakes has shown that due to the lack of specific seismic details for
beam-column joints, the brittle mechanisms of the structure caused by the joint behavior …

This paper presents the results of an experimental and numerical study on strapping method
for retrofitting deficient interior RC beam-column joints, which do not meet the requirements …
