Abstract:
Tests were made at the Materials Testing Laboratory of the University of Havana with 59 rectangular section concrete columns having longitudinal reinforcement with ties and flat ends with slenderness ratios varying from 21.6 to 43.0. The results of loads, stresses, and deformations are given and a Rankine type formula is developed based on these, to establish the relation between the strength of short columns and of columns with high slenderness ratios. Using this relation, another Rankine type formula is suggested for practical design of short, intermediate, and long columns. This formula is compared with formulas of the American Concrete Institute, British, German, and Russian codes.
