THE EFFECTS OF USE OF EXPANDED CLAY AGGREGATE CONCRETE ON STRUCTURAL BEHAVIOUR AND BASIC STRUCTURE COST
Abstract
In this study, the effect of use of lightweight concrete obtained with expanded clay aggregate which provides to manufacture of high strength lightweight concrete on structural behavior and basic structure costs of the structure have been investigated. In the present study, a building having four-storey was designed, and then mechanical properties of expanded clay aggregate concrete (ECAC) and traditional concrete were respectively used for analyzing reinforced concrete design. Cross section of reinforced concrete member, dead weight of structure, structure earthquake response and reinforcing bar and the amount of the total concrete and formwork were investigated after the results of the research analysis. Basic structure costs of the designed structure used both ECAC and traditional concrete were calculated. As a result; it is seen that, compared with the traditional concrete, the dead weight of the structure made with ECAC was reduced by %42, so that the total structure loads were decreased approximately 1,9 ton per square meter and also cross section of reinforced concrete members, foundation thickness and the earthquake loads on the structure were decreased. Consequently, basic structure costs of structure made with ECAC was reduced compared with the structure made with traditional concrete.
Abstract
Bu çalışmada yüksek dayanımlı hafif beton yapımını sağlayan genleştiril kil agregası ile elde edilen hafif beton kullanımının, yapı davranışı ve kaba yapı maliyetine etkisi araştırılmıştır. Çalışmada 4 katlı betonarme bir bina tasarlanmış ve tasarlanan binanın betonarme hesaplarında genleştirilmiş kil agregası ile hazırlanan beton (GKB) ve normal beton mekanik özellikleri ayrı ayrı kullanılarak analiz edilmiştir. Analiz sonucunda betonarme eleman kesitleri, yapı zati ağırlığı, yapı deprem davranışı ile donatı, beton ve kalıp miktarları incelenmiştir. Tasarlanan binada GKB ve normal beton kullanıldığında oluşan kaba yapı maliyetleri hesaplanmıştır. Sonuç olarak; GKB ile yapılan yapının zati ağırlığının normal betona göre %42 oranında azaldığı, böylece zemine gelen yükün m²'de yaklaşık 1,9 ton azaldığı, yapı eleman kesitlerinin, yapı temel kalınlığının ve yapıya etkiyen deprem kuvvetlerinin azaldığı, kaba yapı maliyetlerinin de normal betona göre azaldığı görülmüştür.
