In this study design and construction technique for joint-less integral abutment for short to mid span bridges was developed. Expansion of superstructure due to thermal effect was absorbed in the flexible pile-type abutment in stead of expansion joint in the conventional bridges. Design method for pile subject to vertical and horizontal force was proposed. Backfill, approach slab and details of its connection joint with pavement was also proposed.

본 연구에서는 시공성을 고려한 변단면을 갖는 합성형 강상자형교의 최소비용을 구하기 위한 자동화 최적설계 프로그램을 개발하였다. 강상자형교 설계에 필요한 설계 제약조건은 도로교 표준 시방서를 비롯한 각종 설계기준과 실무자의 경험을 바탕으로 정식화하였다. 최적화의 효율성을 위해 강상자형교의 특성을 고려한 제약조건 소거기법, 설계 변수 연결기법, 응력 재해석 기법을 적용하였다. 본 연구에서 개발된 프로그램은 구조해석 모듈, 최적설계모듈, 사용자의 입력 편의를 위한 전처리모듈 설계 업무자동화를 위한 후처리모듈로 구성되어 있으며, 구조해석은 신뢰성이 입증된 상업용 구조해석 프로그램인 RM-SPACEFRAME을 이용하여 격자모델에 대해 실시하도록 하였다. 또한 개발된 최적 설계 프로그램의 효율성과 실용성을 확인하기 위하여 몇 가지의 수치예제를 적용하였다. 본 연구에서 개발된 최적설계 시스템은 향후 타 형식의 교량에 최적설계 프로그램의 모형으로 활용될 수 있으리라 사료된다.

In order to improve the digging load capacity of a domestic excavator model. computer aided design(CAD) technique was applied to the optimum design of the excavator boom. From this study, the digging load capacity of both the bucket cylinder and the dipperstick cylinder could be made about same and the overall digging load capacity could be increased by about 50%, also, the computer program package developed in this study can be flexibly applied to the design of other construction machines by changing and/or adding a few subprograms and the input data.

Introducing the concept of construction safety in the design/engineering phase can improve the efficiency and effectiveness of safety management on construction sites. In this sense, further improvements for safety can be made in the design/engineering phase through the development of (1) an automated hazard identification process that is little dependent on user knowledge, (2) an automated construction schedule generation to accommodate varying hazard information over time, and (3) a visual representation of the results that is easy to understand. In this paper, we formulate an automated hazard identification framework for construction safety by extracting hazard information from related regulations to eliminate human interventions, and by utilizing a visualization technique in order to enhance users' understanding on hazard information. First, the hazard information is automatically extracted from textual safety and health regulations (i.e., Occupational Safety Health Administration (OSHA) Standards) by using natural language processing (NLP) techniques without users' interpretations. Next, scheduling and sequencing of the construction activities are automatically generated with regard to the 3D building model. Then, the extracted hazard information is integrated into the geometry data of construction elements in the industry foundation class (IFC) building model using a conformity-checking algorithm within the open source 3D computer graphics software. Preliminary results demonstrate that this approach is advantageous in that it can be used in the design/engineering phases of construction without the manual interpretation of safety experts, facilitating the designers' and engineers' proactive consideration for improving safety management.

본 논문은 스마트폰에서 건축설계를 할 수 있도록 3D로 설계과정을 표현하였다. 먼저 건축자재들을 컴포넌트로 구성하고 컴포넌트들을 패턴으로 조립하여 패턴 단위로 건축설계가 이루어지도록 하였다. 모바일 환경에서 건축설계가 이루어 질수 있도록 4가지의 View로 구성하여 각각의 기능을 기술하였다. 또한 각 View에서 필요한 기술들을 사용된 라이브러리를 통하여 자세히 설명하였다. 이러한 구현 기술을 바탕으로 각 View가 어떻게 그 기능을 수행하여 서로 상호 보완적인 방법으로 동작하는지 그 과정과 자재 계산 결과들을 모바일을 통하여 보여주었다.

The object of this study is to develop computer programs with which ordinary engineers can analyse or design steel-concrete composite teams using optimization technique. Various design ana construction techniques which could maximize load carrying capacities and control concrete tension cracks effectively are studied and included in the programs. Analysis results show that proposed construction techniques can reduce steel weight by about 10%∼20% compared with ordinary composite beam. Concrete tensile stresses can also be controlled affectively by the suggested techniques.

In manufacturing industry, image scanning technique has made enormous progress in past decades. 3D models have been also very important to continuously monitor the related spatial information for freeform buildings. The process of shape making of 3D scanning is as follows: mesh surface segmentation, NURBS surface generation, and parametric solid model generation. We will review the process and applying process. Especially in the construction industry, 3D data collection by laser scanning has become an high quality 3D models. Therefore, in this research, we have an effort to review construction of reverse design process for freeform envelope using 3D scanning. The technology enables many 3D shape engineering and design parameterization of reverse engineering in the construction site.

In this research it is concentrated first of all on the attempts to reconstruct the historical context of the idea for the space design based on the natural construction and to re-appropriate il critically to the present context. Sequentially in the areas of philosophy, biology, neuroscience, and architecture it has been variously discussed on the problems about the synthesis of biology and techniques. In the context of the consilience of biology and technique Werner Nachtigall, who has intended to shed light on the morphological principles in the natural construction, founded the 'Bionik', which is different from the bionics or the biomechanics that are oriented to the imitation of natural forms. The space design that is on the basis of the Bionik treats organisms as a functional whole. Therefore the Bionik space design follows two kinds of principle such as the principle of analogy and the principle of optimization. After all the understanding of the consilience of nature and technique for Nachtigall and Bionik designers tends toward the explication of the complex process in which the human perceptions, the environment, and the phenomenal techniques are united together, and this complex process is associated with the space design based on the Bionik.
