通过有限元数值模拟分析方法对 CFRP 加固后的板柱结构进行了一次、二次受力的力学性能分析,数值模拟分析结果表明:加固后的构件的承载力和刚度都得到了相应的提高,板跨中挠度减小,同时,二次受力情况下的碳纤维应力明显滞后。
通過有限元數值模擬分析方法對 CFRP 加固後的闆柱結構進行瞭一次、二次受力的力學性能分析,數值模擬分析結果錶明:加固後的構件的承載力和剛度都得到瞭相應的提高,闆跨中撓度減小,同時,二次受力情況下的碳纖維應力明顯滯後。

The paper undertakes the primary and secondary load dynamic performance analysis of the slab-column structure after CFRP consoli-dation with the finite element numeric simulation analysis method,proves by the numeric simulation analysis results that the loading capacity and stiffness of the construction members after the consolidation can be improved respectively with the reduced deflection of the span,and the carbon fiber stress can be lagged behind under the secondary load.
