Özet:

 Near-fault earthquakes with high amplitude, long-period pulses have a destruction potential for seismically isolated buildings. Since the number of historical near-fault earthquake records is not sufficient for comprehensive studies, synthetic pulse models can be used to simulate these records. The effectiveness of different pulse models has been investigated for seismically isolated structures; however, in these studies lead core heating, which is known to have significant effects in near-fault earthquakes, was not taken into account. In this study, in order to investigate the success of pulse models in determining the seismic response of isolated buildings exhibiting lead core heating under the effect of near-fault earthquakes, nonlinear time history analyses were performed under historical near-fault earthquakes and synthetically produced counterpart ground motion records. The results showed that although general behavior can be determined with pulse models, differences can arise due to lead core heating.

 Yüksek genlikli, uzun periyotlu pulslar içeren yakın-fay depremleri, sismik yalıtımlı binalar için yıkıcı bir potansiyele sahiptir. Tarihi yakın-fay deprem kayıtlarının sayısı kapsamlı çalışmalar için yeterli olmadığından; bu kayıtları simüle etmek için sentetik puls modelleri kullanılabilmektedir. Geliştirilen farklı puls modellerinin etkinliği, sismik yalıtımlı yapılar için araştırılmış; ancak bu çalışmalarda, yakın-fay depremlerindeki etkilerinin önemli düzeylere çıkabildiği bilinen kurşun çekirdek ısınması göz önüne alınmamıştır. Bu çalışmada, puls modellerinin taban yalıtımlı binaların yakın-fay depremleri etkisinde kurşun çekirdek ısınmasına bağlı sismik tepkisini belirlemedeki başarısını araştırmak amacıyla, tarihi yakın-fay depremleri ve sentetik olarak üretilmiş eşdeğer yer hareketi kayıtları etkisinde zaman tanım alanında doğrusal olmayan analizler gerçekleştirilmiştir. Sonuçlar, puls modelleri ile genel davranışın belirlenebilesine karşın kurşun çekirdek ısınmasına bağlı olarak farkların ortaya çıkabileceğini göstermiştir.
