A prototypical building that represents the energy characteristics of buildings can be used as a mean of improving building energy efficiency by supporting policy makers, researchers, architects and engineers. This paper is a fundamental study for the definition of prototypical office building models of Korea. First of all, the term "prototypical buildings" was defined in the context of the representatives of building stock by examining the meanings used from many previous researches. Then, building energy related DB of Korea that is available from public and governmental organization such as MLIT (Ministry of Land, Infrastructure and Transport) and KEEI (Korea Energy Economics Institute) is analyzed in terms of materials for prototypical building definition. Finally, numerous prototypical building studies since 1990's from all of the world were classified with three criteria based on the degrees of the used DB and assumptions in defining prototypical building. The found three criteria are EDPB (Empirical Decision based Prototypical Building), HIPB (Hybrid Information based Prototypical Building) SAPB (Statistical Analysis based Prototypical Building).

In this study, we analyzed applicability of object database, designed the concept model based on object-oriented idea for measurement data management, and applied the design model to object database. The concept model composes three sub models Infrastructure managing information model, Infrastructure measurement data model, and Measurement unit model. The process to expand measurement data of new type was executed easily without changing database schema in object database. The process to expand measurement data of new type was executed easily without changing database schema in object database. Therefore, applicability of new technology to infrastructures for building a safety management network of road bridges could be increased with object database system.

The rational Management of the school facilities will be able to minimize the waste of budgets, enhance total values of facilities. The purpose of this study is to propose promotion plans of the private infrastructure investment in the school facilities not only for contemplating obstacle reasons of BTL projects, but also for gripping contents about process of BTL projects. To achieve these objectives, this study 1)analyzes the major trend about private infrastructure investment, and 2)suggest extended suggestions for minimizing problems in the process of BTL projects in school facilities.

With reent changes in energy sources, infrastructure facilities for energy charging are increasing around living areas. The infrastructure facilities have a slight possibility of explosion, and for this research on protection is needed. In this study, the performance of the reinforcement type is reviewed by examining the destructive properties after applying the impact by the high-velocity projectile to the cement composite to which various reinforcement methods are applied.

The need for maintenance of bridge infrastructure is increasing due to aging, and the cost of maintaining the infrastructure must be calculated for effective budget distribution. Therefore, in this study, representative defects according to bridge superstructure type are derived to calculate the cost for each repair method. First of all, the representative bridges, PSCI girder bridge, Rahmen bridge, Steel box girder bridge, and RC slab bridge, were selected as superstructures using BMS data, and repair methods for defects were presented. In addition, the cost of the repair method by superstructure type was compared. This result is expected to predict total maintenance costs in consideration of the maintenance cycle.

Due to the deterioration of infrastructure, the importance of maintenance is continuously increasing. Therefore, an integrated maintenance method for various facilities is required. In this study, a maintenance priority determination method for integrated maintenance of roads and pipe network facilities was developed. It is possible to analyze attribute information by using GIS data of roads and pipe networks, and shape information can be used. This information is derived as quantitative figures for determining maintenance priorities. In the future, it is expected that facility maintenance can be further advanced in connection with maintenance method and quantity information for each facility.

The purpose of this paper is to analyze the Korean government's investment priorities for the establishment of a supercomputer joint utilization system using AHP. The AHP model was designed as a two-layered structure consisting of two areas of specialized infrastructure, a one-stop joint utilization system service, and four evaluation items for detailed tasks. For the weight of each evaluation item, a cost efficiency index considering the annual budget was developed for the first time and applied to the weight calculation process. AHP analysis conducted a survey targeting supercomputer experts and derived priorities with 22 data that had completed reliability verification. As a result of the analysis, the government's investment priority was high in the order of dividing infrastructure for each Specialized Center and building resources in stages. In the future, the analysis results will be used to select economic promotion plans and prepare strategies for the establishment of the government's supercomputer joint utilization system.

This study investigated and analyzed overseas construction supervision systems to propose improvements for domestic supervision practices. The findings indicate a need for strengthening the role and responsibility of the ordering organization, sharing the workload and reducing the burden on supervisors, establishing a supervision work evaluation system. By implementing these recommendations, it is anticipated that the quality and effectiveness of construction supervision can be significantly enhanced.

This paper deals with steel braced frame as increasing the lateral strength and ductility in order to seismic retrofit of existing buildings and discusses the designing criteria and calculation method of retrofitted buildings. The addition of steel braced frame can be effective for increasing the lateral strength and ductility of existing buildings. However, There is a problem in utilizing this method. It is the approach to provide an adequate connection between the existing RC frame and the installed steel braced frame, because global strength by failure mode(three type) depends on detail of connection and strength of existing RC frame. So, the designer must be confirmed if it satisfies the required performance or not. Failure mode of type I is the most appropriate for increasing the lateral strength and ductility. Seismic performance evaluation and strength calculation of seismic retrofit are performed by guideline by KISTEC(Korea Infrastructure Safety & Technology)'s "seismic performance evaluation and rehabilitation of existing buildings" and Japan Building Disaster Prevention Association. Buildings are modeled and non-linear pushover analysis are performed using MIDAS program.
