Abstract

Purpose: This study presents a new fuse connection, which is a replaceable seismic joint apparatus that ensures that no structural member is damaged, including itself. Study design/methodology/approach: Three beam-to-column connections, one of which is formed with the frictional and elastomeric joint apparatus, one of which is formed with the four-bolted unstiffened end-plate, the other is formed with the four-bolted stiffened end-plate, were analyzed via non-linear finite element simulation. HE240A beam and HE300B column were used in the connections. All the connections were analyzed under cyclic loading until the end of the 7% radian story drift angle.

Findings: The finite element analyses show that the beam-to-column connection with the frictional and elastomeric seismic joint apparatus has more energy dissipation capacity and can transfer more moment value compared with the bolted end-plate connections. Moreover, the beam-to-column connection with the frictional and elastomeric seismic joint apparatus has displayed no damage in any structural member, including itself. However, the bolted end-plate connections have displayed local buckling failure on the beam. Originality/value: The frictional and elastomeric seismic joint apparatus is at a level that can compete with its foreign patented counterparts, thanks to its replaceability, as well as having the desired strength and flexibility of the moment connection types presented in Türkiye Building Earthquake Regulation-2018. In addition, the patent processes are currently progressing in the presence of TÜRKPATENT, the United States Patent and Trademark Office, and the European Patent Office.
