Abstract: | Brick walls are often used as an infill element serving as partitions or as cladding in structure frames. In structural frame design method, infill walls are usually considered to be inert “nonstructural” elements and known for affecting on strength, stiffness and post peak behavior of the structure. The structure is assumed to carry the transverse loads by the frame elements resisting primarily in flexure. Often action of infill wall in frame analysis is ignored in the seismic area which is not on safe side and creates a major hazard during earthquake. RC frames having brick walls are a universal practice in countries like Turkey, where the region is prone to seismic activity. The structures in high seismic areas are greatly vulnerable to severe damages. Apart from the gravity load structure has to withstand to lateral load which may develop high stresses. Nowadays reinforced concrete frames are most common in building construction use around the world.
In this study, all the case studies are design under Turkish Building Codes TS 500 and Turkish Earthquake Codes TEC2007. An extensive analysis of typical RC building configurations, including brick masonry infill walls arranged either regularly or irregularly (creating soft-storeys) has been carried out. Pushover analysis method was carried out in SeismoStruct. Each case was compared to find out the performance of brick wall on RC frame. ÖZ: Tuğla duvarlar betonarme çerçeve sistemlerinde bölme duvar olarak sıklıkla kullanılmaktadır. Bu elemanların yapıların dinamik özellikleri üzerinde olumlu veya olumsuz etkileri olabilmektedir. Ancak, yapısal analizlerde dolgu duvarların sadece ölü yükleri hesaba katılarak bu etkiler gözardı edilmektedir. Bu da kimi zaman deprem etkisinde tehlike yaratabilmektedir. Betonarme çerçeve dünyada sıklıkla kullanılan yapı sistemlerindendir. Türkiye gibi deprem riski olan ülkelerde dolgu duvarların olumsuz etkilerinin yapısal analizlerde ihmal edilmesi, deprem yüklerinin etkisini artırabilecektir.
Bu çalışmada seçilen örneklemelerde TS500 ve 2007 Türk Deprem Şartnameleri kullanılmıştır. Örneklemelerde dolgu duvarların olumlu etkileri için düzenli, olumsuz etkileri için ise düzensiz olarak (yumuşak kat oluşumu da gözetilerek) yerleştirildiği durumlar ele alınmıştır. Düzenli ve düzensiz yerleştirilmiş dolgu duvarlara sahip yapılar, dolgu duvarların olmadığı sistemlerle de karşılaştırılmıştır. Bu maksatla SeismoStruct programı ile yapılan statik itme analizi sonunda elde edilen kapasite eğrileri kullanılmıştır. |
