[提要]  进行了40根预应力砌体柱的受压试验。试验结果表明，对砌体柱施加预应力，尤其在大偏心情况下，能够大大改善其受力性能，提高抗压承载力，扩大其使用范围。分析了影响后张预应力砌体柱受压承载力的各主要因素，研究了施加预应力后砌体柱受压破坏形态的改变，并探讨了预应力损失和加载过程中预应力钢筋应力的变化。

The tests of 40 post-tensioned masonry columns are carried out in order to treat their behavior. The experiment results show that prestressing masonry columns, especially the elements with large eccentricity can improve their performance. increase compressive strength and expand their application scope. Based on the test results, the main factors influencing the carrying capacity of post-tensioned masonry columns, changes of destructive form, pretressed loss and variances of stress of prestressed tendon in course of loacl are studied.
