【摘要】 随着抗震研究工作的日益发展和深入,世界各国开展了大量试验研究,取得了丰富的研究数据,同时美国、日本等国相继建立了钢筋混凝土墩柱抗震性能试验数据库,提高了数据的使用率,为研究人员提供墩柱抗震性能研究的良好平台,极大促进了该领域的研究。然而,虽然国内各高校及研究机构也开展了大量墩柱抗震试验,但由于没有较为系统、完整、合理的数据系统,导致国内所做试验数据利用率低、缺乏统一性,造成了资源的浪费在一定程度上阻碍了国内研究成果的交流,不利于我国桥梁抗震研究水平的提高。为了及时反映我国当前墩柱抗震性能试验研究的水平,充分利用已有的研究成果,有效推动我国桥梁墩柱抗震性能研究的发展,亟需建立我国自有的桥梁墩柱抗震性能拟静力试验数据库。本文以美国PEER墩柱性能数据库和日本Kawashima试验室墩柱抗震性能数据库为主要研究对象,对其数据库的组成结构进行了深入的解构。在此基础上,提出了钢筋混凝土墩柱抗震性能拟静力试验数据库的基本架构,为我国墩柱性能数据库的建立提供一定的理论支持和参考依据,文章主要内容如下:①概括了近年来强烈地震中钢筋混凝土桥墩的震害特点,总结了国外桥墩抗震性能数据库的现状;②对比分析了国内外墩柱抗震性能试验研究情况,提出墩柱性能延性指标体系和拟静力试验数据库结构体系;③解构了美国PEER墩柱性能数据库和日本Kawashima试验室墩柱抗震性能数据库,研究了两个数据库的特点并对进行对比分析,指出各自优缺点及可借鉴之处;④提出了我国墩柱抗震性能试验数据库的基本架构,指出建立该数据库所需要的资源以及如何进行数据库建立。更多还原

【Abstract】 As the development of seismic research, lots of experiments have been done all over the world and boundary data have been achieved. To use the data much more effectively, American and Japan have built their own seismic behavior database of reinforced concrete column, which successfully provided good platforms for research- ers to study the seismic performance of reinforced concrete column. However, although lots of experiments have been done in China, and also plenty of results have been gained, there is still no systematic, complete, and reasonable structural performance database of reinforced concrete column, which leaded to a low utilization rate and bad unity of the test data. In order to show the current experimental level on seismic behavior of reinforced concrete column timely, use existing research results effectively, and promote the seismic performance of bridge columns in China, the establishment of our own seismic behavior database of reinforced concrete column is more and more urgent.In this paper the PEER Structural Performance Database (USA) and Kawashima Laboratory Seismic Behavior Database of Reinforced Concrete Column(Japan) have been taken as the main object of study, through comparing the two databases, the infrastructure of seismic performance of reinforced concrete columns was proposed, which will provide a theoretical basis and reference value for the establishment of seismic behavior database of reinforced concrete column database in China.The research have been done as follows:①Summarized the recent earthquake damage on the characteristics of reinforced concrete bridge piers, researched on the foreign status of the database on the seismic performance of bridge piers;②Made a comparison of the seismic research of Pier globally, proposed pier ductility performance index system and the database of quasi-static test system;③Analyzed the database of the PEER pier performance database (USA) and the Kawashima Laboratory pier seismic performance database (Japan). The characters of each database have been researched and the advantages and shortcomings have been listed respectively; ④Proposed the basic structure of the pier seismic performance database in China, pointed out the resource required for the database and the steps to build it.更多还原
