复合纤维抗震加固异型柱框架试验研究

Test on the seismic behavior of special-shaped columns' frame strengthened with composite fiber

本文通过对混凝土异型柱框架,在加固前和加固后的低周反复加载试验,初步对比分析了复合纤维抗震加固的效果。试验研究表明,复合纤维抗震加固,能够提高异型柱框架的水平承载能力和变形性能,但进入非弹性段后水平变形有增大的趋势。

A frame structure model with L-shaped and special -shaped column is tested and investigated before and after strengthened by composite fiber. Many important results, including the capacity and the deformation, are discussed and analyzed. The paper concludes that the frame with special-shaped columns can be retrofitted with FRP.
