Development of Passive Controlled Structure Assembled With L-Type Diaphragm

Using the high-strength bolted connection, it is possible to control the quality of the joint and improve the construction of the structure. By setting the energy absorption mechanism on the structure and enhancing the damping effect, it makes it possible to scale back the influence of the earthquake. Based on the statement above, a new type of beam column joint (L-type Diaphragm) was developed and tests and analysis were conducted to validate the performance of this joint and the energy absorption characteristics at the end of the beam were surveyed. The stress transfer mechanism of the joint was investigated in the shaking table test of the actual size frame structure with this joint. As a result, it was found effective and a higher reliability.
