현장 공사의 제약이 많은 플로팅 건축 상부시설에서 모듈러 시스템 적용 방안 정립을 위한 기초 연구로서 모듈러 시스템이 적용된 유럽의 사례를 분석하여 이를 유형에 따라 분류하였다. 플로팅 건축 상부시설에서 모듈러 시스템 적용 유형은 단위 건축물 모듈러 유형, 단위 공간 모듈러 유형, 계획 개념으로서 모듈러 유형으로 구분될 수 있었다. 유럽에서 가장 많이 사용된 유형은 소규모 풀로팅 주거 건축에서 적용된 단위 건축물 모듈러 유형이었고, 단위 공간 모듈러 유형은 중규모 이상의 건축물에 적용 가능한 유형이었다. 계획 개념으로서의 모듈러 유형은 실현된 사례는 많지 않았으나, 건축물의 다양성을 수용할 수 있는 유형이며, 플로팅 건축의 영역을 확장하여 플로팅 도시와 같이 보다 큰 규모의 영역에 적용될 수 있는 가능성을 내포하고 있다.

최근, 모듈러 구조 시스템은 공기를 단축시킬 수 있는 장점으로 인해 건설 현장에 적용되고 있다. 모듈러 구조시스템은 단위 모듈로 구성되며, 모듈과 모듈의 볼트접합을 위해 보-기둥 접합부에 개구부를 가공하게 된다. 일반적으로 모듈러 구조시스템은 기존 철골모멘트골조와 유사한 하중전달체계를 가지는 것으로 가정하여 설계된다. 이와 같은 설계 가정의 타당성을 확보하기 위해, 단위 모듈의 보-기둥 접합부에 대한 회전 성능이 파악되어야 한다. 본 연구에서는 개구부의 구조적 영향이 고려된 접합부의 회전성능을 파악하기 위해 유한요소해석을 수행하였다. 해석결과 단위모듈은 충분한 변형능력을 가지고 안정적인 이력거동을 하는 것으로 나타났으며, 단위모듈의 접합부는 부분강접 접합부로 분류되었다. 또한 본 연구에서는 단위 모듈의 비선형 골조 해석을 위한 간단한 스프링 모델을 개발하였으며, 단위 모듈의 비선형 이력 거동을 구현하기 위해 Ramberg-Osgood 이력 모델을 제시하였다.

The unit modular construction system is a building technique in which unit modules are manufactured at a factory and then assembled at the construction site. It has many benefits, including reduction of the construction period and improvement in quality. For this reason, it is utilized for various purposes in Japan and England. While it has been introduced in Korea, there have been few Korean studies conducted on the unit modular system. In particular, little research has been done on the method of safely fixating the unit modules to a truck. Therefore, this study reviewed the fixation methods of unit modules for transport, analyzed the problems, and designed a fixation device for unit modules. In addition, a device for the fixation of unit modules to a truck was developed, and a structural simulation was implemented for a safety test by considering the maximum stress generated during the transport of the unit modules fixed on a truck. When the device for the fixation of unit modules is manufactured based on the results of the structural simulation done in this study, it is expected to aid the development of a more practical fixation device for unit modules.

This Study developed library of parts, applied with 3-dimension character which has width, length and height and a reference plane, for the system development of BIM design on housing unit modular. The current BIM software has not the concept of a reference plane or work tolerance in modular, so the development of parts library applied to unit modular has not moved forward. So, we developed, in this study, parts library applied to windows, built-in-furniture, kitchen systems and knock down bathrooms, with a reference plane and work tolerance based on single roon prototype on urban-life-housings. BIM library can utilize changed size and work tolerance of parts, and fabricating reference plane will be created automatically when an engineer puts work tolerance in the BIM library with supplement of some category related to work reference. Through this BIM library development, we consider the part module can be used for housing complex planning, and architectural designers will be able to utilize the BIM library for housing complex design.

In modular architecture, manufacturing drawing which includes whole information for modular unit production is essential since works for modular unit have to be performed in manufacturing factory not construction field. Although the manufacturing drawing is important as known it is insufficient to utilize the manufacturing drawing in modular architecture project and this makes modular unit low-quality with re-work and work time delay. To prevent low-quality modular unit caused by insufficient manufacturing drawing, in this research firstly manufacturing drawing's current situation and error cases in manufacturing phase of past modular housing project were analyzed, and correlation between reduction of errors occurance frequency and improving manufacturing drawing was verified. Secondly manufacturing drawing improvement factors were deducted in interior, furniture, mechanical work phase which errors' occurance rate is high and the way of deducting manufacturing drawing lists and contents were suggested with light-weight work as an example in case of new type of errors occurance. A series of research process can contribute to good-quality modular unit by errors reduction. As a result of research, about half of errors occurance can be reduced with suggested manufacturing drawing improvement factors. And the manufacturing drawing process can contribute to modular production which have uniform quality.

Modular construction technique is an adaptation of factory-based mass production concept in ordinary manufacturing industries to construction industry and it assumes that panels, units, etc. are fabricated in factories and assembled in construction sites. Given its structural limitations, modular construction technique is primarily used in low-story buildings whose maximum height is usually five stories, but researchers are actively studying possible adaptation of modular construction technique to high-rise building designs these days as in the case of infill-type modular construction design. Infill-type modular construction technique, most frequently used in high-rise building construction projects, completes frame construction first in reinforced concrete structures and fills unit modules in such structures. However, infill-type modular construction technique leads to longer construction schedule accompanying increase in construction cost, cost overrun due to additional of temporary work, and possible damage to units in the wake of facility construction. Accordingly, this study is performed as a basic study for the development of bottom-up infill-type modular construction technique intended to construct structural frames and fill in units sequentially in a bid to address such drawbacks of current infill-type modular construction technique.

With the progress of national policy researches on the modular construction, many studies have been conducted regarding the standardization of interior building materials. However, studies on the standardization of exterior building materials are still insufficient, and there are no dedicated exterior materials for modular construction. In this regard, this study investigated the necessary of standardization through the analysis on 7 kinds of exterior materials used in general buildings and exterior building materials applied to modular apartment houses in order to establish design criteria for the standardization of dedicated modular exterior materials. Based on the analysis results, assembly reference plane in conjunction with inside dimensions was set, and panelizing standardized in five parts was proposed to solve the problem of low exterior material standardization rate. It also proposed elastic gasket and steel bracket details that can compensate for the fabrication errors of unit boxes and construction errors in stacking.

The purpose of this study is to conduct a comparative analysis between Korea and the United States of the supply process of unit modular housing at both the factory production phase and the transportation and lifting phase, as part of an attempt to invigorate the unit modular housing market in Korea. Unlike the practice in the United States, one of Korea's unique characteristics is that the floor is constructed with reinforced concrete and hot water heating system. To do this, the wet method in Korea is used that includes concrete placement, curing and constructing hot water floor heating system at the factory production phase, which results in a longer production time and also requires the lifting of heavier loads. In the United States, interior and exterior finishing works of modular housing are performed by different companies, and the distance between the unit module factory and the construction site is quite far. This kind of dualized production structure may cause confusion when it comes to schedule management, procurement management, and stock management. Moreover, problems caused by external environmental factors such as wind and rainfall were reported in the course of long-distance transportation. The results of this case comparison are expected to provide fundamental data that will reduce the amount of trial and error in the unit module production, transportation and lifting work in Korea, which has a comparatively small number of unit modular housing cases.
