Earthquakes cause serious damage to buildings and result in heavy losses to society,
therefore, it is necessary to enhance the seismic capacity of existing buildings via structural …

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 …

The beam-hinge failure modes are recommended in the existing seismic design codes of
reinforced concrete (RC) frame systems, to reduce the collapse risk under strong …

This paper reports an experimental investigation of the seismic performance of exterior
beam-column joints reinforced with Grade 600 longitudinal reinforcing bars in beams and …

After a seismic event, damage quantification is necessary for safety evaluation, collapse
proximity judgment, and measurement of the residual seismic capacity of the joints. Machine …

The seismic performance of existing buildings can be improved significantly through the
installation of various retrofit technologies. Decision support systems can be used for the …

In this study, various retrofit methods for concrete columns with non-seismic reinforcement
details were developed and investigated: steel jacketing, carbon fiber reinforced polymer …

A major cause underlying the collapse of reinforced concrete (RC) moment-resisting frames
observed in past earthquakes is the shear failure of nonseismically detailed exterior beam …

Beam-column joints are fundamental structural components of a stable structure. Corner
joints are more likely to fail due to their small size and inferior confinement. This calls for …

In this paper, six half-scale exterior beam-column joint connections are casted and tested
under cyclic loads to investigate and evaluate the possibility of using high performance fiber …
