THE DISCUSSION OF THE CALCULATION METHODS OF BEARING CAPACITY OF NORMAL SECTION OF R. C. ECCENTRIC COMPRESSION MEMBER WITH CIRCULAR SECTION

The eccentric compression member with circular section is one kind of reinforced concrete structures that has been widely used and the calculation on bearing capacity of R. C. members with circular section is much more complicated than those with the rectangular cross-section. To simplify the calculation, corresponding assumptions have been given by various existing standards. Based on the analysis and comparison of the process of simplification as well as the contents of various calculation methods, analysis and comparison have been done to the precision of the calculation results of certain examples by using various calculation methods and the conclusions have been given. This study would contribute to the design and calculation of bearing capacity of R. C. member with circular section in a more convenient and efficient way.
