Dolgu Duvarlı Betonarme Çerçeveli Binalarda Hakim Periyodun Belirlenmesi

Günümüze kadar yapılan çalışmalarda, dolgu duvarların yanal rijitliğe olan katkısı ve bina periyoduna etkisi belirlenmiş, hemen hemen bütün deprem yönetmeliklerinde dolgu duvarların bina periyod değerlerine etkisi ampirik formüllerde bir katsayı olarak dikkate alınmıştır. Ancak dolgu duvarların elastisite modülü, kalınlığı ve dolgu duvarda yer alan boşlukların etkisi gibi parametreler ampirik formüllerde yer almamıştır. Bu çalışmada, dolgu duvarların elastisite modülünün, kalınlığının ve boşluk oranlarının periyoda etkisi nümerik modeller üzerinde analiz edilmiş ve diğer çalışmalarda elde edilen ampirik formüllerle karşılaştırılmıştır. Elde edilen sonuçlar mevcut binalar üzerinde kontrol edilmiştir

Anahtar Kelimeler:

Dolgu duvar, Dolgu duvar elastisite modülü, Dolgu duvar boşluk oranı, Dolgu duvar kalınlığı, Yapı titreşim periyodu

Prediction of The Fundamental Periods for Infilled RC Frame Structures

The contribution of infill walls to lateral stiffness and their effect on the natural vibration period of the buildings has been expressed in many studies. An infill wall’s effect on the natural vibration period of a building is taken into account by empirical formulas in almost all earthquake codes. These formulations are based on the structures’ height and the infill walls are taken into account by a coefficient. However, such parameters like wall thickness, modulus of elasticity of the walls and opening ratio in infill walls are not considered. In this study the effects of the thickness, modulus of elasticity and opening ratio of an infill wall on the natural vibration period are analyzed and the results have been compared with empirical formulas obtained from other studies in the literature.

Keywords:

Infill Walls, Structure Vibration Period, Infill Wall Thickness, Infill Wall Modulus of Elasticity, Infill Wall Opening Ratio,
