The purpose of this study was to investigate the performance of precast concrete copings for precast segmental PSC bridge columns. The proposed system can reduce work at a construction site and makes construction periods shorter. The precast concrete copings provides an alternative to current cast-in-place systems, particularly for areas where reduced construction time is desired. A model of precast concrete copings was tested under quasistatic monotonic loading. As a result, proposed precast coping system was equal to existing cast-in-place system in terms of required performance. In the companion paper, the experimental and analytical study for the performance assessment of precast concrete copings for precast segmental PSC bridge columns is performed.

세계적으로 스마트폰 성장의 축이 중저가로 이동하고 IoT에 대응하는 성장 모멘텀을 찾는 추세이다. 최근 구글의 조립식 스마트폰 프로젝트(Ara)의 진행은 전략적 기술지향점과 지속적인 시장지배전략을 수렴해가려는 산물로 분석된다. 구글안경(2013), 스마트워치(2014), 조립식스마트폰(2015) 등의 상용화출시나 출시예정에 대한 발표는 기존 시장에서 전개되어온 구글의 OS플랫폼 지배전략(70~80%)을 하드웨어 플랫폼을 통해서도 전개할 것임을 강력히 시사하고 있다. 한국은 스마트폰 이후를 준비하면서 조립식 스마트폰과 워치의 파괴적 영향에 대비하여, 심층적인 기술개발 및 시장 대응전략의 수립과 IT융합 산업의 동력원으로 연계하기 위한 연구가 시급한 시점이다.

본 연구원에서는 삼성건설에서 생산시공되고 있는 조립식주택 부재에 대하여 공업화주택 성능인정 기준과 관련된 항목중 단열, 차음, 내화성능등의 성능을 분석$\cdot$평가하여 PC조립식부재에 대한 기술자료를 마련하고자 하였다. 또한, 기존 조립식주택을 대상으로 주거환경과 직접적인 영향을 미치는 벽체 및 적합부의 단열 및 결로, 공간차음성능, 바닥충격음 차단성능, 급배수설비 소음 성능등에 대한 실물실험 및 현장실측조사를 통해 파악함으로써 조립식주택의 주건환경을 분석$\cdot$평가하였다. 각 항목별 성능에 대한 종합적인 분석결과, PC아파트의 기존의 현장타설 RC아파트는 주거성능 측면에서 별다른 차이를 보이지 않았으며, 단열성능 등 몇가지 요소에서 PC아파트가 상대적으로 우수한 것으로 분석$\cdot$평가되었다.

This paper investigates the seismic behavior of a prefabricated composite column which is made by onsite connection of precast composite column segments to accelerate bridge construction. Quasi-static cyclic loading tests were performed on three prefabricated composite columns with different connection details to find their seismic capacity. Test results show that the onsite connections remains in elastic range and no slip is observed as designed in spite of plastic hinge formation at the column. The test results also indicate that the prefabricated composite column has better overall seismic capacity compared to a conventional reinforced concrete column with seismic details.

Currently, the prefabricated bridge having the effects to reduce the term of works and the cost of construction is often studied and countries such as America have already developed members, the parts of it, and the technique of construction. In addition, they have supplied them to the fields. The study of prefabricated method of steel composite bridge, which has the precast deck - plate and main girder fixed by high tension bolt and can resist horizontal sheer, is being progressed. However, it is difficult to understand the characteristics of the prefabricated bridge's behavior when the superstructure of the prefabricated method is analyzed by applying to the analysis model of existing bridges. Therefore, this study has the purpose of understanding real structural behavior of prefabricated bridge through comparison and analysis between the structural analysis model reflecting the characteristics of the real prefabricated bridge's superstructure and real size experiment.

Recently, a great progress has been made in bridge construction technology through the development of high performance materials and new structural types. However, most of attention has been paid to the cast-in-place technologies and material cost saving. The cast-in-place method is always subject to some environmental damages in construction sites, which frequently causes conflicts with residents. To overcome the disadvantages, a lot of fabrication construction method was developed. Most fabrication construction methods developed up to now have been applied for superstructure of bridges. In contrast, such fabricable methods developed for substructures are extremely rare. A fabricated column using ICH CFT(Internally Confined Hollow CFT) column was developed in a series of previous researches. Included in the previous studies are design and construction methods for the precast segmental coping, the column-coping connection, the column-segment connection, column-foundation connection. In this paper, seismic performance of the fabricated ICH CFT columns was extensively investigated experimentally. Two test specimens were prepared depending on the connection methods of segments; one by mortar-grouting method and the other by reinforcement method using stiffeners.

Recently, in field of bridge construction, modular technology has been studied to reduce construction period. However, main stream of the study is limited to the pier, girder and deck of bridge, which are huge or main members. Studies on incidental facilities like concrete barrier is out of sight. Thus, in this study, connection system of concrete barrier was developed to apply to modular bridges and static experiment was performed in order to verify structural capability of proposed system. Variables of experiment are composed of bolt direction such as vertical and horizontal. The experimentation due to the designed variables was conducted by comparison with a standard concrete barrier, which is a traditional barrier. As a result, vertical joint way of the bolt showed nearly identical structural performance and healthy to standard specimen's. it can be applied to modular bridges.
