Research on seismic behavior of prefabricated concrete beam-column joints

Abstract In recent years, with the development of society, the construction method of cast-in-place has been unable to fully adapt to the needs of social development. The construction industry has ushered in new development opportunities, gradually to technology, energy-saving and pollution-free development. Prefabricated buildings have been promoted by reducing construction pollution, saving energy and improving labor efficiency. Different types of joints will directly affect the stability and seismic resistance of the whole structure, and also determine the progress of the prefabricated building. Therefore, the prefabricated reinforced concrete beam and column joints are very necessary to study the seismic performance. In this paper, the seismic performance of assembled concrete frame beam and column joints, assembled concrete beam-buckling column-steel restrained support joints and a new kind of prefabricated pin concrete beam-column joints are summarized and analyzed.
