PENGARUH PENGEKANGAN SENGKANG TERTUTUP DAN TAMBAHAN SENGKANG VERTIKAL PADA JALUR GAYA TEKAN KOTSOVOS TERHADAP KAPASITAS LENTUR DAN DAKTILITAS BALOK BETON BERTULANG

Abstract

Abstract: Concrete is a brittle building material due to its weakness against tension force, in other words, concrete has low ductility. For overcoming this weakness, it uses steel material as reinforcement in longitudinal, tranversal or bridling directions. This research is aimed to investigate the impact of bridling in compression path of concrete against bending capacity and ductility of normal quality concrete with weak reinforcement. Four concrete beams in size of 200x300x3000 mm with two types of bridling; traditionally and in Kotsovos’ compression path, are tested. The result shows that two beams with Kostovos bridling have bigger bending capacity of 11.27% than those with traditional bridling. However, all four beams have same ductility behaviour.
