Experimental Study on Seismic Performance of Precast Beam Column Connection Using Steel Fiber

Abstract

This study proposes a unique type of precast beam-column joint with a dry and wet connection that comprises 5D-Dramix. Special connectors, such as double grouted sleeves, are used to join the column and joint elements. The dry connection is quicker to put together than the wet kind, which can substantially limit the extent of manpower required on the construction site. In addition, it is simple to disassemble, making it possible to upgrade components and replace any that have been damaged by earthquakes during the course of the building's lifetime. It promotes industry and increases the building's resistance to earthquakes. It is ideal for areas that experience significant seismic activity and for building. A precast joint model and a cast-in-situ joint model were built, and pseudo-static tests were carried in order to assess the seismic performance of the dry connection and wet connection. According to the test results, the precast joint's carrying capacity is nearly similar to that of the cast-in-situ joint. Strong column and weak beam is the basis for the precast joint's failure mode, and beam damage is seen in the plastic hinge zone.
