摘　　要：对6个FRP-混凝土-钢管组合受弯构件开展试验研究,试验构件外截面包括方形和圆形两种,内部统一采用圆钢管。考察的主要参数包括构件截面形状(圆形和方形)、FRP种类(单向和双向)和FRP层数(1～2)。试验结果可供在实际工程中应用该新型组合构件时参考。A total of six specimens were tested under pure bending to investigate the behaviour of FRP - concrete-steel double-skin tubular beams. Three circular and three square specimens were included where circular steel tubes were used as the inner tubes for all specimens. The main experimental parameters considered were the section type （circular and square）, the type of FRP sheets （uni-directional and bi-directional ）, and the number of FRP layers （1 - 2 ）. The test results provided useful information for the design and applications of this innovative type of composite members.
