Abstract:
Self-Compacting Concrete (SCC) was developed in the later 1980’s and has attracted a wide interest in the world due to its unique properties. This study investigatesthe workability and earthquake resistance of SCC. Several chemical admixtures are added to the concrete to adjust its workability. The workability of fresh concrete is tested using different methods including slump cone, inversion slump cone, L-box and Orimet apparatus. Then the best SCC mixture ratio is selected for microstructural and earthquakeresistance investigations. The earthquake resistance of SCC is investigated on concrete frame. Two frames with the same size are designed and but one cast with SCC and theother one with ordinary concrete. The two frames are tested under low-cyclic loadingusing MTS loading system. ANSYS software is used to simulate and analyze the statictest. The test results give indication how the materials characteristics and constructability of SCC affect earthquake resistance behavior of the frame.
