【摘要】 研发了一种新型高强铝合金组合构件——即在铝合金薄壁管外部包裹碳纤维布并在内部灌注高强砂而形成的组合构件。完成了10个铝合金空腔构件和10个高强铝合金组合构件的轴压承载力试验,得到了轴压构件的破坏模式、极限承载力以及荷载-位移曲线。试验结果表明,高强铝合金组合构件的极限承载力和刚度均比铝合金空腔构件大幅提高,可广泛应用于地下结构的快速修复和加固。更多还原

【Abstract】 An innovative type of high-strength aluminum alloy composite member:the aluminum alloy tube with high strength mortar inside and carbon fibre reinforced polymer(CFRP) sheet wrapped outside was developed.Axial compression bearing capacity experiments of 10 aluminum alloy cavity tube and 10 aluminum alloy composite tube were completed.The failure mode,axial compression capacity and load-deformation curve of specimens have been analyzed.The experiments revealed that the aluminum alloy composite tube has higher capacity and higher rigidity than the aluminum alloy cavity tube,which can be widely used in rapid repair and reinforce of underground structures.更多还原
