A SIMPLE NUMERICAL APPROACH FOR DETERMINING LOAD-BEARING CAPACITY OF RC CONFINED COLUMNS

摘要

The paper presents a numerical model for determining load-bearingcapacity of R-C columns of circular cross-section. The presentedmodel uses the finite difference method and adopts stress-strainrelationship for confined concrete by MUGURUMA et al. The comparisonof theoretical values of ultimate load, determined with pre- sentedmodel, and experimental ones of 44 columns tested by GODYCKI-CWIRKO,KORZENIOWSKI and NAGRODZKA-GODYCKA shows correlation satisfactory forprac- Tice.
