窄翼缘PEC中长柱轴压整体稳定性能试验研究
为研究窄翼缘PEC中长柱轴压整体稳定性能，设计制作9根组合长细比介于76~141（正则化长细比介于0.84~1.55）的窄翼缘PEC中长柱，进行轴压整体稳定性能试验。研究窄翼缘PEC中长柱的初始弯曲、长细比、混凝土强度等因素对其破坏模式和轴压整体稳定承载力的影响。试验结果表明，窄翼缘PEC中长柱在轴压荷载下的破坏模式表现为绕弱轴的弯曲失稳，长细比和初始弯曲显著影响试件的破坏模式和极限承载力。当试件的正则化长细比大于1.0，初始弯曲大于<italic>L</italic>/1 000时，试件的破坏模式表现为整体极值点失稳；当试件的正则化长细比大于1.0，初始弯曲小于<...
