Many of the facility management information system are being operated by each government departments and Acts. Therefore, it is difficult to share and integrate data through the network because data standard codes are not established. In spite of these problems, the Special Act on the Safety Management and maintenance imposes duties on the main agent of national infra structure management and the maintenance results should be integrated in Infra Structure Information Management System(FMS). Thus we propose the structure classification standard codes for the FMS to integrate and analyze safety and management data.

In this study, the seismic performance of weak-axis steel moment connections was investigated through cyclic testing of two full-scale specimens by reducing flange plate thickness. As a result, two specimens were showed that enough energy dissipation capacity and ductility.

This paper presents analytical studies on the cyclic behavior of column-tree steel moment connections by FEA. The column-tree moment connections are composed shop welded beam-to-column connection and field bolted beam-to-beam splice. Two analytical model of column-tree moment connections were designed with beam splice lengths of 900mm and 1,100mm, which are roughly 1/6 and 1/7 of the span length of 7,500mm. In order to verify the FEA reliability, the analytical results was compared with experimental results. Meanwhile, the experimental results were understood better through analysis procedure.
