预应力钢板箍加固RC柱轴压性能试验研究
Experimental study on axial compression behavior of RC columns retrofitted by prestressed steel jackets
摘要
Abstract
Five RC short columns retrofitted with prestressed steel jacket (PSJ) and one RC short column were tested under static loading to investigate the axial compression resistant behavior and compression bearing capacity of retrofitted columns. The main test parameters were prestressed level of PSJ (η) and configuration characteristic value of PSJ (η). The test results indicate that compressive strength of retrofitted column is enhanced effectively and the ductility of the columns is improved significantly. The compression resistant mechanism of PSJ is discussed and the compression bearing capacity of retrofitted columns are analyzed. It is indicated that the strength development coefficient of PSJ depends on the prestressed level and configuration characteristic value of PSJ. According to the superposition method, a formula is suggested to calculate the compression bearing capacity of the retrofitted columns. The calculated results show good agreement with the test results.关键词
