摘要

摘要: 对5块配置新型钢芯-纤维复合拉结件（steel-glass FRP composite connector，简称SGCC）的全尺寸预制混凝土三明治墙板的抗弯和复合性能进行了试验和理论研究。试验结果显示：三明治墙板的抗弯承载力跟拉结件的总数量不成比例，主要取决于拉结件的布局；沿墙板短边布置的拉结件数量和间距变化对墙板的抗弯承载力和复合性能有较显著的影响；墙板屈服前，墙板端部相对于墙板中部和1/4处的拉结件数量变化对墙板抗弯承载力和复合性能的影响更明显；三明治墙板均表现出部分复合性能，复合作用程度跟抗弯承载力呈正相关；试验结果与理论计算结果吻合良好。

Abstract: An experimental and theoretical study was conducted on the bending and composite properties of five full-size prefabricated concrete sandwich panels with new steel-glass FRP composite connectors （SGCCs）. The experimental results showed that the bending bearing capacity of sandwich panels was not proportional to the total number of SGCCs， mainly depending on the arrangements of the SGCCs. The number and spacing of SGCCs arranged along the short edge of the panel had a significant impact on the bending bearing capacity and composite properties of the sandwich panel. Before the yield of the sandwich panel， the changes in the number of SGCCs at the end of the panel relative to the middle and 1/4 of the panel had a more significant impact on the bending bearing capacity and composite properties of the sandwich panel. Sandwich panels exhibited partially composite properties. The degree of composite action was positively correlated with the flexural bearing capacity. The experimental results were in good agreement with the theoretical calculation results.
