在役混凝土梁式桥的抗震加固研究

对已建桥梁按照新的抗震设计规范进行抗震性能评价,根据评价的结果采取相应的抗震加固措施,考虑采取足够的构造措施和基于性能设计方法保证结构的整体延性,防止桥墩等构件的局部破坏,按照最新抗震规范,对某一在役混凝土梁式桥桥墩采取一定的加固措施,通过计算分析验证抗震加固的有效性,对地震作用下桥梁结构的安全性提出探讨

The Seismic Strengthening of Existing Concrete Beam Bridge

Evaluate built bridge’ s seismic performance by the new seismic design code, according to the result of evaluation to take corresponding seismic reinforcement measures, ensure the overall ductility of structure by considering enough structural measures and design method based on performance, prevent local failure of the components such as bridge piers, according to the current seismic code take reinforcement measures for concrete beam bridge piers in use, demonstrate the effectiveness of seismic strengthening by calculation and analysis, give a discussion of the safety of bridge structure under the action of the earthquake.
