FRP管-混凝土-钢管组合双壁空心柱抗震性能的研究进展
Advances in seismic behavior of hybrid FRP-concrete-steel double-skin tubular columns
摘要
Abstract
Hybrid FRP-concrete-steel double-skin tubular columns are a novel form of composite columns, which consist of an outer tube made of FRP ,an inner tube made of steel and an annular concrete section in the space between the two tubes. The FRP outer tube has fibers mainly oriented in the hoop direction or close to the hoop direction,which provides confinement to the concrete and enhances the shear resistance;the FRP outer tube could also protect the inner steel tube from the external harsh environment, which improves the anti-corrosion behavior of the novel composite column. Meanwhile,the inner steel tube could act as longitudinal reinforcement to provide longitudinal force to the column; the annular concrete is confined by the FRP outer tube as well as the inner tube,which ensures the excellent ductility and seismic behavior of the novel columns. Based on existing experimental results in the public literature, this paper introduces the existing study on the seismic behavior of this novel composite column, and discusses the influences of FRP tube thickness,the axial load ratio and the compressive strength of concrete.关键词
