이 연구는 일제강점기 군의 갯수를 317개에서 218개로 축소시키고 군의 명칭, 관할구역 및 경계, 그뿐 아니라 군청소재지와 군청사 건축에 큰 변화를 가져온 1914년 군폐합 과정에 주목한다. 연구의 목적은 군폐합 단행 과정에서 조선총독부와 각 도 사이에 오고간 문서를 통해 조선총독부가 취한 군청사 건축방침과 각 도 및 군의 대응, 행정절차, 1910년대 군청사의 건축상태와 업무환경은 어떠했는지를 파악하는 것이다. 이 연구는 문헌연구방법을 사용한다. 기본자료는 국가기록원이 소장하는 조선총독부 문서들 중 군폐합관계서류(국가기록원 정리번호 CJA002545; CJA002546; CJA002547; CJA002548; CJA002550)와 면폐합관계서류 2개 철(CJA002549; CJA002565) 안에 산재하는 군폐합 관련 서류들이다. 그밖에 1910년대 당시 발간된 신문인 매일신보와 기존 연구들도 주요한 자료로 사용한다. 화재나 군청소재지 이전 등 어쩔 수 없는 경우가 아니면 군청사의 신축에 매우 소극적이었고 신축을 위한 예산 배정에도 소극적이었던 조선총독부의 입장과 건축방침이 1910년대 군청사로 기존건물을 전용하거나 신축, 증개축, 개수 등 건축하는데 어떤 작용을 했는지와 당시 군청사의 건축상태 및 업무환경에 어떠한 영향을 미쳤는지 살펴본다. 이를 통해 건축적 특징에만 촛점을 맞춰왔던 기존의 연구시각과는 다른 각도에서 일제강점기 군청사 연구성과를 보완한다.

본 연구에서는 검증시험결과를 활용한 말뚝기초의 경제적인 설계절차를 제안하였다. 그리고 비경제적인 말뚝기초의 설계관행을 해소하기 위하여 6개 사례를 선정하여 설계를 목적으로 한 말뚝 정재하시험 (즉, 검증시험)을 수행하고, 검증시험 결과를 활용하여 건설비용 절감효과를 분석하였다. 말뚝기초 건설비용 절감효과는, 말뚝의 하중지지능력을 확인할 수 있는 소구경 말뚝에서는 34 - 47 %로 나타났으며, 말뚝의 최대하중지지능력 확인이 곤란한 대구경 말뚝에서는 0 - 55 %로 나타났다.

Stud penetrate welding is an important item of composite floor in modern steel structure, especially in high-rise buildings. But it is difficult to get satisfied welding quality due to all kinds of factors. In this paper, the author put forward a new welding procedure named method of energy control through analysis and comparison of the wave curves of stud welding based on large amount of experiments and tests in laboratory and construction areas. The use of this welding procedure in some large engineering in recent years proved that this method is effective and practicable

The main external force of the harbor in east coast is wave. So, wave is the important cause of wave induced current and sediment transport due to wave in planning harbor structures. Therefore, it must be considered not only to secure the harbor tranquility but also the sediment transport due to wave induced current in planning the harbor. In this study, we studied on the influences of construction procedure on harbor tranquility and siltation using annual coastal line data and bathymetry data near breakwater. And it suggests that the construction procedure for the harbor tranquility and the best way for the decrease of harbor siltation.

Lately construction industry tends to prefer remodeling of existing buildings rather than new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. And also, remodeling of building costs less and creates less wastes compared to reconstruction and so it is more profitable in financial and environmental view. However remodeling is process of creating new environment with existing building. Therefor remodeling must follow the procedure realizing problem and fix the problem based on through investigation on existing building and users requirement must be faithfully reflected. Specially in case of apartment houses, since vagueness on ownership and management authority on common parts exists. Hereupon, in this study we are to present the procedure of analyzing apartment house remodeling method through user requirement by approaching to several considerable factors in user request side.

LNG stevedoring plant offshore pipelines requires human power and the longest construction period in constructing LNG storing terminal and influences on the success of the project absolutely. In this paper, the constructing procedures of LNG stevedoring plant offshore pipeline was established. Establishment of constructing procedures of LNG stevedoring plant offshore pipeline includes procurement of main equipments, iron frame and pipelines. To predict any expectable problems, that may occur by the stage of construction the application to the field works with a base of theoretical and practical contents for the constructing procedures of LNG stevedoring plant offshore pipelines can be established.

In this thesis, appearance inspection, compressive strength of concrete test, arrangement of bar inspection, survey, and bearing stress analysis were performed on a damaged coping of reinforced concrete pier to investigate the damage cause. According to the performed a series of inspections, it was found that the coping of pier was damaged during PSC (Pre-stressed Concrete) beam construction. In this thesis, the repair method for damaged pier was studied. The repair procedure used in this thesis was follows : chipping for damaged part, clean by high-pressure, installation of wire mesh, coating of surface hardening, construction of section restoration material, copula grinding, and prevent coating for far-infrared radiation.

This paper summarizes full-scale test results on CFT column-to-flat plate connections subjected to gravity loading. CFT construction has gained wide acceptance in a relatively short time in domestic building construction practice due to its various structural and construction advantages. However, efficient details for CFT column to flat plate connections have not been proposed yet. Based on the strategies that maximize economical field construction, several connecting schemes were proposed and tested. Test results showed that the proposed connections can exhibit punching shear strength and connection stiffness exceeding those of R/C flat plate counterparts. A semi-analytical procedure is presented to model the behavior of CFT column-to-flat plate connections. The five parameters to model elastic to post-punching catenary action range are calibrated based on the limited test data of this study. The application of the proposed modeling procedure to progressive collapse prevention design is also illustrated.

The quality of track-bed fills of railways has been controlled by field measurements of density $({\gamma}_d)$ and the results of plate-load tests. The control measures are compatible with the design procedures whose design parameter is $k_{30}$ for both ordinary-speed railways and high-speed railways. However, one of fatal flaws of the design procedures that there are no simple laboratory measurement procedures for the design parameters ($k_{30}$ or, $E_{v2}$ and $E_{v2}/E_{v1}$) in design stage. A new quality control procedure, in parallel with the advent of the new design procedure, is being proposed. This procedure is based upon P-wave velocity involving consistently the evaluation of design parameters in design stage and the field measurements during construction. The Key concept of the procedure is that the target value for field compaction control is the P-wave velocity determined at OMC using modified compaction test, and direct-arrival method is used for the field measurements during construction. The procedure was verified at a test site and the p-wave velocity turned out to be an excellent control measure. The specifications for the control also include field compaction water content of OMC${\pm}$2% as well as the p-wave velocity.

Super high-rise mixed use buildings require a longer period for construction. Especially finishing work takes up about 40% of the whole construction period. Thus, finishing work is becoming an important factor in determining the construction period along with earth work and frame work. As the expected returns added by the reduction of the period and cost in constructing super high-rise mixed use buildings are huge, the expectations are now increasing for the possible gains. In this respect, as the period of finishing work is easier to be shortened than that of frame work, the efforts to acquire the technical knowledge to reduce the finishing work period are now being required. Accordingly, in this study, we aimed at suggesting the basic data for designing an economic plan for finishing-work procedure by analyzing the productivity of each work type of finishing work procedure on the basis of the execution and results of a construction method as a time-flexible finishing work plan. For this, we categorized the work types of finishing work procedure into each work unit and provided a work-system for each of them. Also, with case studies, we calculated the detailed amounts of the work-loads, required materials, productivity, and productivity index of the main work types of finishing work procedure and each of their separate work units as well as analyzed the relationship between the value results to suggest a better way to improve its productivity.
