摘要
为进一步研究采用板式FRP拉结件的装配式混凝土夹心墙板受弯性能,文章基于通用有限元软件ABAQUS建立数值模型研究了拉结件布置方式、以及混凝土肋厚度对试件平面外初始刚度的影响。研究结果主要表明:对于不带肋的试件,拉结件间距减小会抑制试件平面外剪切变形,使试件平面外刚度逐渐增大;对于带肋的试件,平面外刚度随拉结件间距的增大呈现先增大后减小的趋势;混凝土肋厚度的增加会提高试件平面外刚度,但上升幅度随拉结件间距的减小而降低。
In order to facilitate an in-depth understanding on the flexural performance of the precast concrete sandwich panel with FRP plate type connector,numerical models based on general purpose finite element software ABAQUS was conducted to investigate the influence of the connector layout and the concrete rib thickness on the out-of-plane initial stiffness of the precast concrete sandwich panel.The results indicated that for the specimen without concrete rib,the out-of-plane shear deformation of the specimen would be decreased through reducing the connector spacing and the stiffness would be improved.For the specimen with concrete rib,the stiffness presented an initial increase and followed by a decrease with the increase of the connector spacing.The increase of the concrete rib thickness would improve the stiffness of the specimen,while the improvement would be reduced with the decrease of the connector spacing.
