Investigation of the behavior of connection of reduced-beam-section steel beam to reinforced concrete column

After recent earthquakes that caused major damages in beam-column connections, scientists and engineers proposed new types of connections to postpone such brittle failures. One of these new connections is the connection of steel beam to concrete column and connection of reduced- beam-section to stee...
