The purpose of this research is a seismic capacity evaluation and strengthening of existing railway station buildings, which were constructed before the seismic design code activated. The seismic capacity of 2nd story RC station building is evaluated by using nonlinear time-history analysis. Analysis results are checked by story drift ratio and story shear, which are described in design code. As a result, the story shears are exceeding the base shear of the design code, the appropriate seismic strengthening methods are needed. To improve the seismic capacity, metallic dampers are used. Evaluation parameters are metallic damper shape and damper installation methods. Dampers are installed in four places in X and Y directions of station buildings. By reviewing of time-history analysis results, the metallic damper, which is installed inverted K-brace type, shows a better seismic performance than other damper shape and installation methods.

The degree to which the design of a building embraces maintenance considerations has a great impact on its performance. Modern buildings are designed to meet higher building standards than in previous times. As the result, the influence of design on the maintenance of buildings is greater than ever before. The issue of building maintenance is a universal one and its consideration at the design stage is of great importance on the future performance of the building. Even though many studies have conducted to improve building performance, almost all of the results of those studies have not been utilized effectively during design. The purpose of this paper is to suggest a checklist which could be used for incorporating building maintenance concept in the design. The suggested checklist was made by reviewing previous studies and then refined through consulting with professionals of relevant fields.

This study purposed to investigate the optimal outrigger location in tall building with cap truss after a structural schematic design of 80 stories building was performed by using MIDAS-Gen. In this paper, the main parameters of structural analysis were the outrigger location and stiffness of main structural elements (outrigger, exterior column, shear wall etc). In order to search the optimal outrigger position in high-rise building with cap truss, we analysed and examined the lateral displacement of top floor which is one of the very important considering factors of tall building structural design. The paper results indicated that the outrigger location and the stiffness of main structural elements such as outrigger, exterior column and shear wall had an effect on the optimal outrigger location. And it is verified that the study results provided the basic engineering data for fixing the most optimal outrigger location for minimizing the lateral displacement of tall building.

This study presented a model that can enable a reliability analysis for the repair and replacement cycle of a building by using background repair and replacement data and expert opinion as foundation data and applying Monte Carlo Simulation. The presented model offers the time of the repair and replacement of building elements for the period of a year, and supports the prediction of repair and replacement and expenses demand in advance while planning the maintenance of a building. In addition, the model will significantly reduce the risks to the building owner with regard to maintenance decisions. In addition, when a person in charge of the maintenance of large-scale building assets is having difficulties making decisions regarding the repair and replacement of existing building elements due to a lack of background data to support a long-term policy on the repair and replacement requirements, an engineering solution that can ensure the adequacy of this is provided. In summary, it can be largely divided into three study results. First, a method of estimating the repair and replacement cycle that can deal with the development of a construction system was developed. Second, a probabilistic methodology that can quantify the risk of the repair and replacement cycle was proposed. Third, the proposed model can be used as a means of supporting designer and constructor in making decisions for the life cycle plan of a building during a construction project.

The Ministry of Construction and Transportation has estimated the reconsideration of economy in construction and the dullness of LCC forcast method which supports decision-marking in safety and maintenance of buildings. So, they have introduced LCC analysis method in steps of a feasibility study and design. Because of the introduction of LCC analysis process and method, it would be possible to make a logical decision from management maintenance, estimation, user point of view. In this study, it would bepossible to show a plan and alternative of design factors and structure in one building by using LCC analysis method and to compare and analyze the reduction of life circle cost bi the elapsed time.

Building information modeling (BIM)-based construction projects have increased and become more varied, and as such the management of BIM-based facility information is also increasingly important for facility maintenance. Information management, and specifically product data mapping, however, has some problems in the area of manual data entry and does not adequately consider the exchange requirements of facility maintenance. Therefore, it is necessary to introduce a method to improve the management of composite object information for BIM-based facility maintenance so that it can handle construction operation building information exchange (COBie) data for a composite object. Therefore, we present a method to map COBie data to related materials of a composite object. This research contributes to increasing the efficiency and accuracy of the required information mapping between a building model and product data using a BIM library through optimal BIM data adoption. Moreover, it allows for the creation and management of specific product data at the design development phase.

구조용 재료중에서 목재는 비중에 비하여 강도가 크고. 가공성이 우수하며, 뛰어난 미관을 가지고 있다는 장점이 있지만 다른 건축 구조재료에 비하여 연소와 부식의 우려뿐만 아니라, 쉽게 부패하고 변형이 되는 단점도 가지고 있는 것이 사실이다. 이러한 단점에 의해 생긴 심각한 결함은 건물을 붕괴할 수도 있다. 따라서, 오늘날 목재가 사용된 건축물의 경제적인 유지관리가 중요시 되고 있다. 본 연구는 이질재료와 접합된 노후화된 목재 부재의 성능을 분석하여 쉽게 부패하고 변형이 되는 목재의 효율적인 유지관리방향의 기초를 확립하고자 하는 것을 목표로 하고 있다.

It is necessary to correspond to building users' claims rapidly as much as possible in order to satisfy user's need, because the final tarket of building maintenance service is user of building. This paper investigates the time taken for receiving users' claims and the time taken for the service organization to respond to the claims in the office building; types of claims and service responses are analysed, through which the response characteristics of the maintenance management organization are evaluated with respect to users' claims. Throughout extensive simulation analysis, important performance measures such as mean time to repair and utilization of maintenance personnels have been investigated.
