Research Of On The Database Of Quasi-static Ttest Database Forschema Database Schema Of Sseismic Performance Performance Of Piers

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:â‘ Summarized 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;â‘¡Made a comparison of the seismic research of Pier globally, proposed pier ductility performance index system and the database of quasi-static test system;â‘¢Analyzed 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; â‘£Proposed 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.
