Research On Seismic Performance Of PEC Column Fabricated With Crimping Thin-walled Built-up Section-steel Beam Interior Joint With Post-tensioned BRS Plate Connection

Self-centering structure systems have PT strands which run parallel to the beam,column or wall and are anchored at the exterior columns or foundation,and anenergy-dissipation device such as top-and-seat angles,or friction devices,whichposttensioning bars provide restoring force and self-centering behavior that reduces thepotential for residual drift and alleviates struactural damage process, guarantee seismicenergy-dissipation capability of the structure, reduce the repair cost after earthquake.Considering the seismic performance advantage of self-centering structure and theresistance to lateral stiffness of PEC column Fabricated with Crimping Thin-WalledBuilt-Up Section, and PEC column can provide reliable anchorage for thepost-tensioned(PT) high-strength bolt of the self-centering structure. And for come true thedesign object of compatibility between partial self-centering, energy-dissipation and thesafety redundancy was fulfilled successfully.Therefore studying on seismic performance ofPEC column Fabricated with Crimping Thin-Walled Built-Up Section-Steel Beam Jointwith partial post-tensioned connection has the theory significace on and the practical valueTo investigate the seismic performance of PEC column Fabricated with CrimpingThin-Walled Built-Up Section-Steel Beam Joint with post-tensioned connection. The testspecimen model was the second floor Interior Joint of the frame structure, Considering thecolumn layout were taken as the design parameters. Then the test of two specimensdesigned and fabricated by1:1.6scale which represented the interior joints were conductedunder quasi-static cyclic lateral loading to study the hysteretic behaviors,energy-dissipation capacity, the ductility property,the mechanical deformation patter ofthe connection and force-transfer mechanism of joint. Meanwhile, the finite elementanalysis software ABAQUS was adopted to simulate the hysteretic performance of thespecimens and verify the feasibility of the finite element model by contracting the resultsof test. And systematic analysis relate design parameters(column layout，and the filler plate ofbeam,BRS width, post-tensioned(PT), axial force in the column, the cover plate thickness,the bolt hole shape of split-tee flange and web) the regularity of the influenceThe research on seismic performance of connection between PEC column and steelbeam is comparatively comprehensive and systematic，Get the series relevant results andSuggestions of the research. Which provides theoretical reference for fulture studing andpractical...
