  • By producing pre-engineered modular system in the factory, It is enable to expedite construction and can be distinguished from two types by the method resisting load. One is the open-sided modular system composed of beams and columns. The other is enclosed modular system composed of panels and studs. Of the modular systems, the open-sided modular system buildings the connection between modules are difficult due to closed member sections, and the overall strength is reduced as a result of local buckling. In this study, in order to solve these problems, a modular system with folded steel members filled with concrete are proposed. The capacity spectrum method presented in ATC 40 is used for seismic performance assessment of the proposed model structure and the structure with conventional steel members. The analysis results show that at the performance point of each model the number and rotation of plastic hinge formed in the proposed modular system are smaller than those in the conventional system. Based on this observation it is concluded that the proposed system with composite sections has superior seismic capacity compared with conventional system.

  • 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.

  • 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.

  • Modular system can be divided into two types based on the methods of resisting load. The one is the open-sided modular system composed of beams and columns. The other is the enclosed modular system composed of panels and studs. Of the Modular systems, the use of open-sided modular system is limited because it consists of closed member sections. In order to solve this problem, Choi et al.(2017) proposed a composite modular system with folded steel members filled with concrete. However, it was assumed in the previous study that the connections between modules are composed of rigid joint. Therefore it didn't identify the effect of connection behavior in structure. This study used finite element analysis to calculate stiffness of the connections in the proposed modular system. The linearization method presented in FEMA 440 is used for seismic performance assessment of structures, considering the connection stiffness computed in this study. The result of analysis shows that the capacity and story drift ratio obtained in the model considering stiffness of connection are less than those in the model not considering connection stiffness. Based on this observation, it is concluded that the stiffness of connection has a considerable effect on structural behavior.

  • A unit modular system is a construction method which installs on site by manufacturing 50%~90% of the whole process in the factory. This method can minimize the process in the site and maximize the operation, which will reduce the duration and improve the overall quality. The recent paradigm of construction is to be sustainable building. Modular system can be regarded as a sustainable building construction method because it can reduce the amount of construction waste by recycling partial or whole part of overdue building be torn down. A unit modular system is the answer to cope with the increasing market of small size housings. A unit modular system is the most appropriate option at this point. This research proposes the standard operation and construction process of modular system, which enable to optimal system. A case study of reconstructing small-size housing was introduced to support this proposal. Finished unit modular is the reasonable way. However, 80% of complication rate of the modular is the most rational when a defect occurrence during delivery is considered.

  • Since the late 20C, a lot of fashion designers have considered about new construction system in fashion. Many arguments about architectural form and construction system have being supported on enlargement of range of functionalism fashion through the consideration about new shape and combination among various any other spheres. Modular concept, which is able to divide complex construction of integration into separated basic unit and use various and liberal arrangements, is regarded alternative idea of economic construction that creates new shape and constructive beauty through the simple operation and changing combination continuously. Specially, fashion designs of Yoehlee Teng, John Ribber, and Galya Rosenfeld are estimated that they are effectively utilized architectural modular system pursuing multi-function and multi-change in fashion. Modular system utilized in fashion construction will be classified as follows: 1) layering system of Yoehlee Teng, 2) combine system of john Ribber, and 3) lego system of Galya Rosenfeld. This thesis will presents beneficial guide for simple and practical functionalism fashion design development in 21C.
