Abstract

Being one of the most active seismic zones of the earth; Anatolian peninsula hosts historic masonry structures which carry traces of numbers of civilizations. Dynamic behavior of these structures should be estimated with realistic approaches in order to protect our architectural historic heritage from destructive effects of earthquakes. Difficulties and uncertainties in determination of mechanical properties of masonry structures make their computer models questionable. In this study, a theoretical approach is presented for determination of material properties for structural elements of Lala Mustafa Pasha Mosque located in Erzurum. Theoretical modal analysis was realized over finite element model of the structure; experimental modal analysis was realized by operational modal analysis method. Material properties of the structure were finally defined by evaluating theoretical and experimental modal parameters. Collapse mechanism of the structure was investigated by realizing dynamic analysis of finite element model using 1992 Erzincan earthquake acceleration records.

Özet

Sismik olarak dünyanın en aktif bölgelerinden birisi olan Anadolu yarımadası pek çok medeniyetin izlerini taşıyan tarihi yığma yapılara ev sahipliği yapmaktadır. Mimari kültür mirasımızın depremlerin yıkıcı etkilerinden korunabilmesi için bu yapıların dinamik davranışları gerçekçi yaklaşımlarla belirlenmelidir. Yığma yapılarda malzeme mekanik özelliklerinin tespitindeki zorluk ve belirsizlikler bilgisayar ortamında kurgulanan yapısal modelleri her zaman sorgulanır kılmaktadır. Bu çalışmada Erzurum il merkezinde yer alan Lala Mustafa Paşa Camii’nin taşıyıcı eleman malzeme özelliklerini belirlemek için literatürde mevcut yığma malzeme modelleri incelenerek teorik bir yaklaşım ortaya konulmuştur. Yapının sonlu eleman modeli oluşturularak teorik modal analizi, Operasyonal Modal Analiz yöntemiyle de deneysel modal analizi gerçekleştirilmiştir. Teorik ve deneysel olarak belirlenen modal parametreler irdelenerek yapının malzeme özellikleri belirlenmiştir. Elde edilen sonlu eleman modelinde, 1992 Erzincan Depremi ivme kayıtları kullanılarak gerçekleştirilen dinamik analizler neticesinde yapının göçme mekanizması araştırılmıştır.
