Research on Mechanical Properties of Precast Geopolymer Concrete Sandwich Panels Under Axial Compression

  • 摘要: 设计并制作了6片采用地聚物混凝土和玻璃纤维增强复合材料(GFRP)六角筒形拉结件的预制混凝土夹心墙板试件,对其进行了轴心受压试验,研究了拉结件间距、墙板高度和钢筋混凝土叶板厚度3个关键参数对墙板轴压下的破坏模式、承载力、变形等的影响。试验结果表明:试件均呈现因二阶效应产生的大偏心受压破坏,表现为一侧叶板混凝土压碎和另一侧叶板混凝土水平开裂;随着拉结件间距的增加,墙板的组合性能降低,破坏时混凝土压碎区域面积减小,侧向变形增大,试件承载力逐渐降低(当拉结件间距由300 mm增加至600、 900 mm以及不设置拉结件时,承载力分别下降了17.1%、42.0%、49.5%。);随着墙板高度的减小或混凝土叶板厚度的增加,构件的长细比和二阶效应逐渐减小,破坏时混凝土压碎区面积增大,平面外变形减小,试件的承载力增加(当叶板厚度由50 mm增至75 mm时或高度从2 100 mm降至1 500 mm时,试件承载力分别提高了34.3%、5.9%)。
