STEEL PLATE SLIT DAMPER USING ON STEEL FRAMES

In this study, a steel plate slit damper which was developed in order to avoid damages during an earthquake on steel frames was investigated. The goal of this system is to limit plastic deformation on the slit dampers which can be easily repaired or changed after a heavy earthquake. To investigate the performance of the proposed system, 3 full scale cyclic tests were investigated. The first specimen was a conventional extended end plate beam to column connection. The second one was the strengthened extended end plate beam to column connection and the last cyclic test was conducted on the specimen with a slit damper system. It is indicated from the test results that, proposed connections showed an excellent hysteretic behavior. In addition, the energy dissipation and plastic deformation in this system were concentrated only at the slit dampers.

ÇELYK ÇERÇEVELERDE YARIKLI ÇELYK SÖNÜMLEYYCY KULLANIMI

Bu çaly?mada çelik çerçevelerde deprem syrasynda olu?abilecek hasarlaryn önlenebilmesi için yarykly çelik sönümleyiciler çaly?ylmy?tyr. Bu sistemin amacy plastik deformasyonlary a?yr bir deprem sonrasynda kolayca de?i?tirilebilen veya onarylabilen yarykly çelik sönümleyiciler üzerinde synyrlandyrmaktyr. Bu sistemin davrany?yny izlemek için 3 adet tam tersinir tekrarlanyr yükleme ile deney yapylmy?tyr. Ylk numune alyn levhaly birle?im, ikinci numune güçlendirilmi? alyn levhaly birle?im ve son numune de yarykly çelik sönümleyicili birle?im bölgeli elemanlardyr. Deney sonuçlaryndan önerilen birle?imin iyi bir histeretik davrany? sergiledi?i görülmü?tür. Buna ek olarak, enerji sönümleme ve plastik deformasyonlaryn sadece yarykly metalik sönümleyicilerde yo?unla?ty?y görülmü?tür.
