The Construction-Operations Building information exchange (COBie) is a standardized format to deliver information from the building information model (BIM) to the facility management (FM) system. The purpose of this study is to propose a COBie-based structural maintenance document which can record and review the information with regard to structural safety inspection and maintenance of buildings.

This study is aimed at developing a wireless unified-maintenance system (WUMS) that would satisfy all the requirements for a disaster preventive SHM system of civil structures. The WUMS is designed to measure diverse types of structural responses in realtime based on wireless communication, allowing users to selectively use WiFi RF band and finally working in standalone mode by means of the field-programmable gate array (FPGA) technology. To verify its performance, the following tests were performed: (i) A test to see how far communication is possible in open field, (ii) a modal test on a bridge to see how exactly characteristic real-time dynamic responses are of structures. Finally, the WUMS is proved valid as a SHM, and its outstanding performance is also proven.

This study is a method to improve the reliability and effectivity of maintenance. It is necessary to build the integrated management system of BIM throughout the design, construction and maintenance of the structure. In order to apply BIM, it was introduced structural record management from the design stage. And It helps to improve the reliability of maintenance.

This paper aims to develop a wireless unified-maintenance system(WUMS) to obtain real-time structural response of civil structures. The WUMS integrates the GPS module, the strain module and the acceleration module based on the standalone controller, and includes the RF module for remote measurement and the battery for long term operation. In order to evaluate the performance of the WUMS, a response test using a modal shaker and a modal test using a model bridge were performed. The test results using USMS were compared with those measured by wired system. Finally, the developed WUMS was appropriate to obtain the structural response of the civil structure in real-time, unified, and wirelessly.

It is important to doubt common knowledge established in the past when we face difficulty to seek further development based on them. In this presentation the importance of doubting common knowledge is pointed out for further endless development of the field of study by discussing stagnation of chloride ion ingress and liquid water penetration into concrete, stagnation of water pass through a crack in concrete and the inconsistency between Carbonation depth and cover concrete spalling risk.

This paper is presented in progressive improvement of the construction and maintenance for corrugated steel plate culverts in Korea expressway. After reviewing the technical consulting reports and field surveying this whole structures. It is effectively help to minimize damage and improve the stability of structures.

In this study, periodical configuration survey is carried out on the subject of the suspension bridge in service. Its reliability and structural modeling validity are performed by comparison and analysis of interpretation value through the structural analysis.

The Korean electric power industry autonomously developed the Korea Electric Power Industry Code (“KEPIC”) with political support from the government with a view to creating domestic codes and standards for electric power facilities. Since KEPIC was initially issued in November 1995, the Korea Electric Association (“KEA”) has consistently updated it, developing new codes and standards like Structural Maintenance Inspection and so on.

As numbers of tunnel are increased, the necessity of temporary maintenance works of those tunnels is also increased. This study introduces new space truss frame system for the maintenace of tunnels. Proto-type model was analyzed and evaluated. The result shows that new system may contribute to save the maintenance cost and time.
