STUDIES ON APPLICABILITY OF FAILURE CRITERIA BY LOADING EXPERIMENTS OF FULL-SCALE RC MEMBERS

Abstract

 In this paper, the applicability of failure criteria (thickness increment of RC member, relative displacement at compressive edge, deviation strain second invariant) for seismic safety evaluation of structure have been studied by comparing with results of loading experiments of full-scale RC members. Specimens are W1100mm×D1100mm×H3100mm RC columns. Experiment cases are as follows: Standard case (N-1), Post-installed shear reinforcements (P-1), Loading in diagonal direction (N-2-1), Effects of pre-cracks (N-2-2). N-1, N-2-1 and N-2-2 are shear-failure type, and P-1 is bending-failure type. As a result, relationships between values of failure criteria and damage states of specimens under each condition of experiments are obtained, and applicability of each failure criteria in current manuals is verified.
