Experimental Dynamic Characteristics of Historical Masonry Stone Mosques with Wooden Roof / Tarihi Ahşap Çatılı Yığma Taş Camilerin Deneysel Dinamik Karakteristikleri

Abstract Natural stone masonry mosques with wooden roof are the most widespread historical building of Eastern Black Sea Region in Turkey. The main walls of buildings are made with the combination of natural stone, lime, soil or horosan mortar and their roofs are constituted with wooden elements. Within the scope of this study, it is aimed to determine the dynamic characteristics of masonry stone mosques with wooden roof in the Eastern Black Sea Region in Turkey with nondestructive experimental methods. For the purpose of practice, Rize Gulbahar Mahallesi Buyuk Mosque, Artvin Hopa Sundura Mahallesi Mosque and Trabzon Merkez Tavanli Mosque are selected. Selected mosques have recently been restored and their geometries and properties are similar. The dynamic characteristics such as natural frequency, modal damping ratios and mode shape of the mosques are determined with the Ambient Vibration Test by using the seismic accelerometer. The results of nondestructive experiments obtained from the mosques are compared with each other and the frequency interval for the control of the analytic models of masonry stone mosques with wooden roof is given. Key Words: Mosques with wooden roof, masonry stone mosques, the Ambient Vibration Test,nondestructive test method, Eastern Black Sea Region. Oz Ahsap catili dogal tas yigma camiler, Turkiye’nin Dogu Karadeniz Bolgesinde siklikla rastlanan tarihi eserlerdendir. Camilerin beden duvarlari dogal tas, kirec, toprak veya horosan harci birlesimi ile yapilmis ve catilari ahsap elemanlarla teskil edilmistir. Bu calisma kapsaminda, Dogu Karadeniz Bolgesinde bulunan ahsap catili yigma tas camilerin dinamik karakteristiklerinin hasarsiz deneysel yontemlerle tespit edilmesi amaclanmistir. Uygulama amaciyla, Rize Gulbahar Mahallesi Buyuk Camii, Artvin-Hopa Sundura Mahallesi Camii ve Trabzon Merkez Tavanli Camii secilmistir. Secilen camiler, yakin zamanda restorasyonu yapilmis eserler olup, geometrileri ve ozelikleri benzerdir. Camilerin frekans, sonum orani ve mod seklinden olusan dinamik karakteristikleri sismik ivme olcerler kullanilarak Cevresel Titresim Testi yontemiyle belirlenmistir. Soz konusu camilerden elde edilen hasarsiz deneysel sonuclar birbirleriyle karsilastirilmis ve ahsap catili yigma camilerin analitik modellerinin kontrolu icin frekans araligi verilmistir. Anahtar Kelimeler: Ahsap Catili Camiler, Yigma Tas Camiler, Cevresel Titresim Testi, Hasarsiz Deneysel Yontemler, Dogu Karadeniz Bolgesi.
