This study attempted to figure out the usage of the modular system in other fields through literature review and empirical study, analyze its structural method in fashion. After analyzing architecture & product-related books, the Internet data and previous studies, the modular system's five structural methods were obtained. Then, 991 photos of women's clothes from 2003 to 2014 were collected through the fashion websites in Korea and abroad. The results can be summarized as follows: First, the following five structures were derived: assembling structure, overlapping structure, arrangement structure, inserting structure and folding structure. Second, according to analysis on the structural method of the modular system in modern fashion, overlapping structure (34%) was the most common. Third, in fashion, the use of fastener for installation and removal is important for assembling structure. In terms of overlapping structure, 3D volume by vertical accumulation was commonly observed. Arrangement structure revealed a horizontal and flat shape through simple arrangement. In inserting structure, on the contrary, non-standardized modules were used as a part of clothes or decorative elements. In folding structure, origami technique for reduction and expansion was used.

This paper was conducted to evaluate structural performance of modular system connection with bracket. It was evaluated to two external connection specimens and two internal connection specimens. As a result of experiment, excessive shear deformation of the bracket was observed in all of the specimens. However, all of the specimens satisfied the requirement for intermediate moment frames (IMF) targeted in the experiment.

모듈형 구조시스템은 학교 및 아파트 건물과 같은 저층 및 중층 구조물에 점점 더 많이 사용되고 있다. 최근에는 고층 건물에 모듈러 구조시스템을 적용하는 방법에 대한 연구가 수행되고 있다. 고층 모듈러 구조시스템에 대해 충분한 저항력과 경제적인 구조를 제공하기 위해 복합모듈 구조시스템이 제안되었다. 본 연구에서는 일련의 실험을 통해 단위 복합모듈 구조에 적용하기 위한 목적으로 비대칭 복합 기둥의 강도를 평가하고자 하였다. 실험적 연구는 기둥의 세장비, 편심율 및 관통바 유무에 따라 기둥의 강도에 미치는 영향에 중점을 두었다. 단위 모듈 구조에 대한 비대칭 기둥단면의 설계식을 제안하였다. 결과로부터, 설계식은 단위 복합모듈 구조에서 비대칭 기둥단면의 적절한 강도 예측을 제공한다는 것을 알 수 있다.

At present, the actual condition is that Korean modular structures are limited to a low rise detached house and military barracks. And there is no standardized structural design method of stacked modular structure. Accordingly, in general, they don't review impact force in the stage of stacking and installing a module, the effect which wind load has on a structure in the stage of lifting, and inertial force occurring in the stage of lifting or transporting a module in the process of constructing a structure. Therefore, this study investigated the construction method of modular system to be studied in stages, and decided on the position to which load was applied and boundary condition in structural analysis at each construction stage. Besides, inertial force according to each speed was calculated in the lifting and wheeled transport of module. And we calculated impact load according to lifting speed in module stacking and installation work and wind load due to instantaneous wind speed in the installation work by lifting. On the basis of the suggested method, in the modular system to be studied, it carried out review of structure by changing determining conditions of load being applied by construction stage, such as in the stage of lifting, in the stage of transport, and in the stage of installation, and drew construction conditions securing stability structurally.

최근 구조물의 노후화에 따른 급속 교체, 교통 영향 및 환경 영향 최소화의 요구에 따라 프리캐스트 기술을 활용한 모듈러 교량 연구가활발하게 진행중에 있다. 본 연구는 모듈러 교량과 관련된 연구의 일환으로 모듈러 슬래브 교량의 횡방향 연결부를 대상으로 반복하중 재하 실험을 통하여 횡방향 연결부의 반복 하중에 따른 구조적 거동 특성을 파악하고 사용성 평가하였다. 반복하중의 크기를 결정하기 위하여 RC 보를 1개 제작하였으며 반복하중 재하 실험을 위하여 일체형 RC 보 1개와 분절형 실험체 3개를 제작하였다. 실험결과, 분절형 실험체는 하중 반복 횟수가 증가함에 따라 처짐 및 균열폭이 거의 일정하거나 수렴하는 경향을 나타냈으며, 일체형 RC 보와 비교하여 최대처짐, 잔류처짐, 균열폭 모두 작게 나타났다. 또한 사용하중을 반복 재하한 실험체의 경우, 처짐 및 균열에 대한 사용성 기준을 모두 만족하였다.

This study is to introduce a structural analysis method that can apply a unit modular system to a remodeling extension. The structural analysis process, which can reflect the behaviors between the existing building and the modular system, is performed in a five-staged structural analysis. Therefore, the example of structural analysis of an existing building is introduced.

This study is to establish a structural analysis method that can apply a unit modular system to a remodeling extension. Structural design has to be performed after considering the behaviors between the existing structures and the modular system because the modular system is added after the transformation of existing structures has been processed. The structural analysis process, which can reflect the behaviors between the existing building and the modular system, is introduced in a five-staged structural analysis.

The purpose of this study is to develop structral technologies on the lightweight composite slab systems with sound reduction layers in the modular house. In this study, two kinds of slabs with minimum thickness was suggested reducing the floor impact sound. In order to evaluate the structural performance, the flexural strenth tests were carried out on the one-way full scale specimens. From the results of test, we know that the proposed slabs had ductile behavior and would be safe sufficiently.
