北京市城市桥梁抗震性能的现状
|
摘要
目前,我国的公路桥梁抗震设计规范已经实行了三代。随着设计方法的发展和更新,按以前方法设计的或者根本没进行抗震设计的桥梁,均存在不同程度的抗震安全隐患。为此,对北京市城市桥梁进行了调查分析,选取了9座典型桥梁作为代表,选用抗震性能评估方法中的能力需求比法,对9座典型桥梁进行了详细的抗震性能评估,得出了北京市城市桥梁抗震性能的现状。
The codes for seismic designs of highway bridges have been applied for three generations at present in China.As the seismic design methods have been developed and updated,there are seismic safety hazards of varying degrees for the bridges,which were designed by the former methods or which had no seismic designs.Therefore,Beijing city bridges were investigated and 9 bridges representing the whole city bridges were selected.Then the nine-bridge seismic performances were evaluated detailedly by the capacity demand ratio method of seismic performance evaluations.And the current situations of seismic performances for urban bridges in Beijing is obtained.
