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

摘要

The paper presents a numerical model for determining load-bearing capacity of R-C columns of circular cross-section. The presented model uses the finite difference method and adopts stress-strain relationship for confined concrete by MUGURUMA et al. The comparison of theoretical values of ultimate load, determined with pre- sented model, and experimental ones of 44 columns tested by GODYCKI-CWIRKO, KORZENIOWSKI and NAGRODZKA-GODYCKA shows correlation satisfactory for prac- Tice.
