COMPUTATIONAL ANALYSIS ON SHEAR BEARING CAPACITY OF RC SHORT COLUMNS STRENGTHENED WIHT BFRP

Abstract

Abstract: To analyze shear bearing capacity and failure modes of RC short columns strengthened with BFRP. Low cyclic loading tests were conducted on one comparative short column and two no-destructive RC short columns strengthened with BFRP. The tests show that failure mode, shear strength, ductility are improved and increased for specimens strengthened with BFRP. Shear capacity calculation formula of RC short column strengthened with BFRP has proposed based on test results and current formulae.

Key words: BFRP, concrete, short column, failure mode, shear capacity
