Abstract

Deprem yalıtım teknolojisi yer hareketi ile yapısal sistem arasında bir ayrışım yaratarak depremlerin yıkıcı etkilerini azaltmak amacı ile kullanılan yenilikçi bir tasarım ve güçlendirme yöntemidir. Bu çalışma ¼ ölçekli üç katlı simetrik ve eşmerkezli çelik yapının korunması için önerilen karma yalıtım sistemlerinin sarsma masası deneyleri ile etkinliğinin araştırılması üzerine odaklanmaktadır. Kullanılan pasif yalıtım sistemi, yüksek sönümlü elastomer ve düz yüzeyli sürtünme tipi kayıcı yalıtım birimlerinden oluşmaktadır. Deney programında kullanılan yer hareketi kademeli olarak arttırılarak, yalıtım sisteminde ortaya çıkabilecek davranış farkları araştırılmıştır. Deprem kaydının %100 etkitildiği durumda daha yüksek kayma modülüne sahip olan elastomer birimlerden oluşan yalıtım sisteminin daha düşük kayma modulüne sahip olan deprem yalıtım sistemine oranla taban kesme kuvveti açısından beklenildiği gibi daha yüksek değerler verdiği gözlenmiştir.

Experimental Performance Evaluation of Hybrid Isolation Systems

Abstract

The seismic isolation technology is an innovative design/retrofit method. It decouples the structural response from the ground motion to reduce floor accelerations while concentrating most of the deformation demands at the isolation interface. The main objective of this research study is to investigate the effectiveness of passive-hybrid isolation systems for a ¼ scaled mass concentric three-story steel structure. The passive-hybrid isolation system is a combination of HDRB and PTFE sliding bearings. The ground motion used in the shake table tests is gradually increased to investigate changes in the dynamic response characteristics of the hybrid isolation system. It has been observed that the isolation system consisting of elastomer units with larger shear modulus subjected to higher base shear with displacement demands than the system with the lower shear modulus.
