| 摘 要： | 为了在结构层次上对既有钢筋混凝土建筑结构的抗震加固进行定量分析,使其更具合理性,本文在钢筋混凝土结构抗震能力评估的基础上,建立了结构薄弱环节的加固补强分析和评估体系,确定结构薄弱单元和薄弱楼层加固的合理目标及加固顺序,并评估薄弱楼层及薄弱单元加固的效果及合理性.本文的结构抗震加固评估分析方法能为既有钢筋混凝土结构加固方案的制定提供重要参考,又使抗震加固更具有针对性,经济效益更加明显.

| Abstract: | For the anti-seismic strengthening of the existing reinforced concrete structure,the structure should be analyzed quantitatively to make the strengthening reasonably.Based on the evaluation for anti-seismic capability of reinforced concrete structure,strengthening system for weak story and weak element is built,the reasonable strengthening goal and sequence for story and element reinforcement are determined,and the result and reasonability of strengthening are studied in this paper.The strengthening method ... |
