Abstract

Bölgemizde son yaşanan 6 Şubat 2023 Kahramanmaraş depremleri dahil olmak üzere birçok deprem sonrası yapılan saha çalışmalarında iyi perde duvara sahip ve binada deprem etkisi karşısında iyi çalışmış perde duvarın rijitliği arttırarak yapının ötelenmesini azalttığı ve bu şekilde binanın göçmesinin ağır hasar almasının önüne geçildiği görülmüştür. Buna karşılık binalardaki kusurlu perdelerin ise deprem esnasında ağır hasar aldığı ve binanın toptan göçme riskini oldukça arttırdığı gözlemlenmiştir. Bu kusurlu betonarme perdelerin davranışlarını iyileştirecek alternatif güçlendirme yöntemlerinin geliştirilmesi ya da bu perdelerin belirlenip, binada perdenin güçlendirilerek etkin hale getirilmesi önem kazanmaktadır. Perde duvarın güçlendirilmesi binanın deprem performansına katkı sağlayacaktır. Bu çalışmada yanal yükler nedeni ile betonarme perde duvarlarda eğilme ve kesme etkileri sonucu oluşabilecek hasarların güçlendirilmesine yönelik literatürde birçok çalışma bulunmasına karşılık daha fazla farklı detayların inceleneceği deneysel çalışma yapılması gerekliliği görülmüştür.
