EXPERIMENTAL STUDY ON THE EXTERIOR JOINT USE ULTRA-HIGH PERFORMANCE STEEL FIBRE REINFORCED CONCRETE

Abstract

This paper presents the experimental results and benefit of using UHPSFRC for the improvement of seismic ability of exterior joint under cyclic loading. This experiment was conducted on 3 specimens S1, S2 and S3 where S1 is specimen of normal concrete designed using Eurocode 8 [1] with ductility class high (DCH) while other two specimens using UHPSFRC in joint region. The initial experimental results show that the applying of UHPSFRC in joint region gives better behavior of bearing capacity of 15.8% ad 19.7% reprectively, and displacement increase 25%, and joint shear deformation increased significantly before its failure.
