The purpose of this study is to develop precast concrete modules that can be used as a booth and a single-story building with a large space. This precast concrete module is originally designed to have a hexagonal facade when the upper and lower parts, which are symmetrical about horizontal connection line, are combined. A structural design was conducted to ensure structural safety of these precast concrete modules and to extend the slope of the inclined members as far as possible. Then the finite element analysis was performed to estimate the lateral and vertical deflection of complete precast concrete modular structures. And to verify the structural safety of these precast concrete modules, weight loading tests were conducted on the upper and lower modules respectively.

국내 건축법에는 표준 내화구조인 KS F 1611-5에서 1시간 내화성능을 갖는 각형강관에 대한 사양적 기준만을 제시하고 있어 각형강관에 적용되는 모듈러 건축물을 중⋅고층에 적용하기 위해서는 한계가 있다. 따라서 내화성능 평가를 통해 2시간 인정을 받은 모듈러 구조에 한하여 중⋅고층 건축물에 적용이 가능하다. 본 연구에서는 KS F 2257-1 및 KS F 2257-4 기준에 의거하여 실대형 내화실험을 수행하였다. 평가결과 OW-01 및 OW-02 실험체의 경우 각형강관의 온도상승 및 강도 저하로 인해 면외좌굴이 발생하여 2시간 내화성능을 확보하지 못하였으나, 피복 및 각형강관 두께를 보완한 IW-01 및 OW-03 실험체의 경우 충분한 차열성능으로 인해 2시간 내화성능을 확보하여 중고층 모듈러 건축에 적용하는 것이 가능한 것으로 판단되었다.

To improve the wet process of concrete core wall, which is one of lateral load resisting system in high-rise modular building, the new composite panel system is developed and its structural performance under lateral load is investigated analytically.

Since existing modular construction designs are 2D based, they cannot reflect the characteristics of modular buildings built by a dry construction method, in which objects are assembled and constructed as a unit. This study aims to develop a BIM library information system of modular buildings by utilizing the “Construction Information Classification System” developed already in Korea.

This study aims at understanding of the importance of modeling boundary conditions for connections of modules in 12-story modular building. The peak roof drifts under fixed condition and pinned condition are compared at design intensity levels in this paper.

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.
