摘要:
FRP-混凝土-钢双壁空心柱(简称DSTC)是由香港理工大学滕锦光教授提出一种新型组合构件,具有受力性能良好、施工方便、耐腐蚀性能优越等系列优点.已近期成功将DSTC作为受力构件应用于桥墩.将DSTC应用于桥墩等结构主要受力构件时,持载期间的长期变形性能及持载对DSTC承载能力的影响是一个亟待厘清的关键技术问题.以此为背景,开展了持载对FRP-混凝土-钢双壁空心柱轴压力学性能影响试验研究.主要的研究参数包括:钢管的厚度、GFRP管的纤维层数、是否带焊钉及轴压比.研究结果表明:当DSTC轴压比为0.3及0.4时,持载对DSTC轴压承载力的影响非常有限.
Abstract:
Hybrid FRP-concrete-steel double-skin tubular column(DSTC), with numerous advantages such as outstanding load-carrying capacity, ease in construction, excellent corrosion resistance etc., is a new hybrid composite member invented by Prof. Jin-Guang Teng of The Hong Kong Polytechnic University. Recently, the authors’ research group has successfully implemented the application of the DSTC in bridge piers. When DSTCs are applied to the main load-carrying structural members such as piers, the long-term deformation performance under sustained load and the effect of the sustained load on the load-carrying capacity of the DSTC are key technical problems to be clarified. Against this background, the experimental study on the effects of sustained load on compressive behavior of the DSTC has been carried out. The main research parameters include: thickness of steel tube, thickness of GFRP tube, deployment of shear studs, and axial compression ratio of the sustained load. The test results show that: under the investigated axial compression ratios of 0.3 or 0.4, the effects of sustained load on the axial load-carrying capacity of DSTC are very limited.
