BEARING CAPACITY ANALYSIS OF THE CONCRETE COLUMNS WITH HIGH STRENGTH CORE UNDER AXIAL COMPRESSION LOAD

Based on experimental research on plain concrete columns with high strength core,the formula to predict the bearing capacity of concrete columns with high strength core under axial compression load was brought forward in previous paper,in order to verify the formula whether right,axial compression tests including 3 concrete columns with high strength core and 1 general reinforced concrete column were completed in this paper, and the failure characteristic was analyzed additionally. According to experimental results,it can be shown that the failure modes of the concrete columns with high strength core are similar to those of general reinforced concrete columns,however,the bearing capacity of concrete columns with high strength core is significant high as compared with that of general reinforced concrete columns; the results of the bearing capacity obtained by the literature [3] was in good agreement with the experimental results.
