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.
