摘要
在钢筋混凝土柱进行粘钢加固的实验研究中选择了五种加固方式,在对加固柱大量实验的基础上,研究了加固后混凝土、钢筋、钢板的共同工作性能,给出了各种加固方式下混凝土柱的力一应变关系实验结果,比较了各种加固形式下混凝土柱的极限承载能力,最强加固方式下的极限承载较未加固柱提高37.1%。
In the experiments five forms are chosen to strengthen or repair reinforced concrete columns and the working behavior of steel plates together with concrete and reinforced columns is analysed. The experi-mental results of relations between loads and strains applied to the columns under various strengthening forms are given and the load-bearing capacities of the columns are compared each other. The strongest strengthened column shows a 37.1% increase in the ultimate capacity over the original columns.
