유럽에서 지어진 플로팅 건축물을 중심으로 상부 시설에 적용된 모듈러 시스템을 분석하여 이를 유형에 따라 분류하였다. 플로팅 건축 상부시설에서 모듈러 시스템 적용 유형은 단위 공간 모듈러를 적용하는 경우와 단위 건축물 모듈러를 적용하는 경우로 나누어 볼 수 있었고, 단위 공간 모듈러의 경우 동일 형태의 반복에 의한 유형과 서로 다른 형태의 결합에 의한 유형으로 구분될 수 있었다.

This study is about the case study on the application of modular system to the superstructure of floating architecture in Europe. There are many restraints in the onsite construction of floating architecture. Then, various industrialized construction methods are needed to reduce the portion of the onsite construction in floating architecture. Among the various industrialized construction methods, the modular system can be more suitable for floating architecture. At this background, this study analysed the European cases of the application of modular system and classified the types of applied modular system. As a result, this study could classify the three types of modular system, such as, building unit modular, space unit modular and planning concept modular, and define the characteristics of three types by comparing with each other.

Recently, modular structural systems have been applicable to building construction since they can significantly reduce building construction time. They consists of several unit modular frames of which each beam-column joint employs an access hole for connecting unit modular frames. Their structural design is usually carried out under the assumption that their load-carrying mechanism is similar to that of a traditional steel moment-resisting system. In order to obtain the validation of this assumption, the cyclic characteristics of beam-column joints in a unit modular frame should be investigate. This study carried out finite element analyses(FEM) of unit modular frames to investigate the cyclic behavior of beam-column joints with the structural influence of access holes. Analysis results show that the unit modular frames present stable cyclic response with large deformation capacities and their joints are classified into partial moment connections. Also, this study develops a simple spring model for earthquake nonlinear analyses and suggests the Ramberg-Osgood hysteretic rule to capture the cyclic response of unit modular frames.

Modular structural systems have been used increasingly for low- and mid-rise structures such as school and apartment buildings. Studies have recently been conducted on the application of the modular structural system to high-rise buildings. To provide sufficient resistances and economical construction for the high-rise modular structural system, a composite unit modular structure was proposed. In this study, the strength of the non-symmetric composite column for the proposed composite unit modular structure was investigated through a series of tests. The experimental study focused on the effect of the slenderness of the column, eccentricity, and through bars on the strength of such a column. Design equations for the non-symmetric column for a modular unit structure were also proposed. From the results, it was found that the proposed design equations provide reasonable strength prediction of the non-symmetric composite column for the modular unit structure.

2차 전지는 충방전이 용이하여 적용분야가 급격히 늘어 나고 있으며 대표적으로 납축 배터리를 기반으로 장비등이 제작 사용 되고 있다. 기술의 발전으로 리튬 계열의 2차 전지가 출시 되면서 자동차, 드론등에서 사용되고 있으나 기존 장비와의 전압차등이 존재하여 기존 장비에 적용하기에는 어려움이 있다. 이러한 문제를 모듈 개념을 도입하여 단위 모듈을 기존 납축 전지의 전압에 준하여 구성하고 전류를 최대한 구성하는 방식으로 구성하면 기존 장비 및 신규 장비에 적용이 가능한 방법을 찾을 수 있다.

The purpose of this study is to suggest the plan formation for university dormitory's living unit by the modular unit of the pre-fabricated architecture, Pursuing this, this study conducts the investigation of present domestic situation of prefabricated construction and practices plan formation for living unit concentrating on the dweller's satisfaction by solving the problems which hitherto constructed dormitory had, especially collapse of dweller's territoriality. Consequently, this study presents the feasibility of modular unit of present prefabricated construction as a new method of dormitory's living unit construction, and suggests the pertinent plan formation for the improvement of the dweller's territoriality.

Recently, the government is reinforcing safety management at construction sites to prevent safety accidents in construction works, and the safety management plan of workers is an important situation. Meanwhile, modular construction is expected to be gradually expanded to middle and high-rise buildings, but active measures to ensure worker safety are insufficient. This study is a preliminary study of the development of a checklist for preventive worker safety management. The purpose of this study is to derive a checklist classification system for the safety management of workers in the field of modular construction by preceding studies, case analysis, and expert advisory opinions. The classification system consists of large categories of factory manufacturing, transportation, and on-site construction, and the sub-system consists of six sub-classes: foundation work, frame work, modular frame installation work, finishing work, and facility work. Among them, the sub-classification of modular frame installation work consists of 12 unit works, centering on module lifting and assembly module work, which are the main construction processes. And the classification system reflects the three main management factors and contents for defined safety management. It is expected that the research results of this study can contribute to efficient safety management at the modular construction site.

The rate of application of the modular plant in the plant industry is increasing, and for the success of the modularization projects, it is essential to develop and implement a systemized methodology across all phases of the project. However, Korean EPC firms lack project management capability when it comes to apply standardized methodology. Therefore, it is important to establish and systematize the cost/schedule integrated management method which are the two core elements of project management technology. This study was conducted to develop a methodology and guidelines for integrated management process for modular plant projects. The researchers developed a methodology for planning and managing cost and schedule, and integrated by module unit. Integrated cost and schedule methodology and guidelines developed can be used for various EPC modular plant projects to enhance the efficiency of project management.

Domestic construction industry has experienced many difficulties as it has been on a downward. It's a way that active modular structure market to solve this problem. However, as Modular structure technical standard in Korea is in the early stages, our modular factory maufactured rate is almost 40% lower than overseas. Besides, there is less design diversity so it just applies for a few buildings like low-rise building and general group barrackes. To deal with these problems, it is essential to modulating the equipment which can improve the production rate. This will help to ensure the quality, shortening of the construction period, the reduction of labor costs. We have defined the name of segmented by each installation location of the equipment to modulating equipment. And it was examined the suitability of the modulating of the location-specific utility system. The results of the analysis are discussed on the page.
