玻璃钢加固对提高偏心受压柱抗压强度的试验研究

EXPERIMENT RESEARCH ON IMPROVING COMPRESSIVE STRENGTH OF ECCENTRICALLY LOADED COLUMNS STRENGTHENED BY FIBER REINFORCED PLASTIC

玻璃钢是一种新兴的建筑材料。主要通过试验的方式 ,探讨了玻璃钢作为结构加固材料 ,对提高偏心受压柱抗压强度的作用。试验分为大、小偏压两种情况 ,分别由用 2、3、4、5层玻璃钢加固的试验柱和未加固的对比柱组成 ,逐根进行单调加载试验。通过对试验结果的分析 ,为今后实际工程中偏压柱的玻璃钢加固提供了试验和理论依据。

This experimental research concentrates on the effects of fiber reinforced plastic(FRP) as a new material to implement structural reinforcement in improving the strength of eccentrically loaded columns.Two cases of large and small eccentricity are considered.Simply- loading test is conducted on the testing columns of each case,which includes the columns reinforced by 2,3,4, and 5 layers of FRP and the column without reinforcement.The analysis of testing results provides a testing and theoretical basis for actual usage of FRP reinforcement.
