In contemporary architectural practice, flat sections and plan drawings are no longer a primary means of representation and communication with participants. A typical building design has an ornamental exterior wall system and a roof system that should have water-proof quality and drainage function. By comparison, distinction between exterior wall and roof are unclear in freeform buildings, and they are integrated into a concept of a building envelope. This study is to propose 3D coordinate control technology for freeform structure by CNC curved tube method in order to develop a BIM-based envelope design and construction method for freeform building. Because a much wider freeform building construction can be achieved with correct 3D data and easy-to-implement in construction field, the proposed 3D coordinate control technology is highly recommended for practical use instead of the conventional CAD system.

본고에서는 <모던보이>와 <암살>의 탈식민주의적 재현을 공간 중심으로 살펴보았다. 이 영화들은 이중도시론을 탈피한 잡거지로서 본정과 종로를 보여주었다. 이는 탈식민의 잡종적 주체를 가능하게 하는 지점으로 사유될 수 있다. <모던보이>의 본정 재현은 미쓰코시 옥상정원, 명동성당, 남산음악당을 중심으로 이루어졌다. <암살>의 본정 재현은 아네모네 카페와 미쓰코시 백화점에 주목했다. <암살>은 본정의 미쓰코시 백화점을 투쟁 장소로 재현했다. 종로/북촌에 조선총독부 신청사를 건립되었던 역사를 배경으로, <모던보이>는 조선총독부를 투쟁의 장소로 설정하였다. <암살>의 종로 재현은 친일파 강인국 저택을 중심으로 이루어졌다. <모던보이>와 <암살>은 '여성' 민족주의 영웅을 통해 근대의 이항대립적 경계를 돌파하는 탈식민주의적 재현을 보여주었다. 또한 본정을 잡거지인 동시에 탈식민주의 운동의 본거지로 묘사하여 기존의 경성 재현과 다른 양상을 보여주었다.

Advances in the technology of computational design are giving architects and engineers the opportunity to analyze buildings with complex geometries. This study explores the optimization and automation process using the parametric design method, and uses digital tools to achieve surface representation and panelization for curved shaped office buildings. In this paper, we propose parametric algorithms of dimensional and geometric constraints using the Knowledge-ware scripts embedded in Gehry Technologies' Digital Project. The knowledge-based design methods proposed in this study can be used to systemize the knowledge possessed by experts in the form of data. Such knowledge is required to promote collaboration between designers and engineers in the process of CAD/CAE/CAM. The aim of this study is to integrate the process into design, which establishes an integrated process. This integration enables two-way feedback between design and construction data by combining the methods used in designing, engineering, and construction.

In this letter, we propose a novel approach to detecting and tracking apartment buildings for the development of a video-based navigation system that provides augmented reality representation of guidance information on live video sequences. For this, we propose a building detector and tracker. The detector is based on the AdaBoost classifier followed by hierarchical clustering. The classifier uses modified Haar-like features as the primitives. The tracker is a motion-adjusted tracker based on pyramid implementation of the Lukas-Kanade tracker, which periodically confirms and consistently adjusts the tracking region. Experiments show that the proposed approach yields robust and reliable results and is far superior to conventional approaches.

The Architecture, engineering & construction (AEC) industry domains have grown more complex and larger. BIM is a digital representation of a building to facilitate the exchange and development of construction information integration and interoperability. Industry Foundation Classes (IFCs), under development by International Alliance for Interoperability (IAI), represent the part of buildings or elements of a process. IFC has been adopted as a central information repository in order to deliver integrated information. BIM softwares could open the IFC file, recognize standard objects. However, sometimes, information distortion or information loss occurs during information exchange. As project participants exchange BIM information by using BIM softwares they will need a reliable and efficient exchange of information. This paper suggests the BIM object information compatibility problems among BIM softwares and classify the BIM object information compatibility problems.

In mechanical design, design process is mainly composed of design, explanation and evaluation. In this paper, Using Genetic Algorithms (GA), Evolutionary computation is introduced as new design process. This method promote the efficiency and power of design. Due to the known characteristics of the stage, the approach basically involves a synthetic design method with the composition of building blocks representing the elements of mechanical objects. In order for the building blocks to be more suitable for representation and evolution of mechanical structures, Elementary Cell Blocks (ECBs) are introduced as new building blocks. In this paper, we have demonstrated the implementation of the approach with the design of gear systems.

In this paper, a systematic technique is proposed for the optimal placement and design of nonlinear dampers for building structures. The concept of Output Frequency Response Function (OFRF) is applied to analytically represent the output frequency response of a building frame where nonlinear viscous dampers are fitted for suppression of vibration during earthquakes. An effective algorithm is derived using the analytical representation to optimally determine the locations and parameters of the nonlinear dampers. Various numerical examples are provided to verify the effectiveness of the optimal designs. A comparison of the vibration suppression performance with that of the frame structure under a random or uniform damping allocation is also made to demonstrate the advantages of the new designs over traditional solutions.

The general method of structural analysis for building structures has been based upon the assumption that all dead loads are imposed on a building simultaneously throughout the entire structure. In reality, buildings are built floor by floor or a few floors at a time. The construction dead load is applied gradually onto the structure as the structure is being erected. The prevailing commercial software for structural analysis used to date have resulted in the representation of inaccurate structural behaviors. The actual construction sequence and the loading of the structure ere not properly represented in the analysis. This paper identifies the source of the errors and develops the algorithm to account for the differential column shortening due to construction dead load based upon a given construction sequence

Recently, an efficient and practical method has been developed for the generation of univariate non-Gaussian wind pressure time histories on low building roofs; this methodology requires intermittent exponential random numbers for the simulation. On the other hand, the conventional spectral representation scheme with random phase is found suitable for the generation of univariate Gaussian wind pressure time histories on low building roofs; this simulation scheme requires uniform random numbers. The dependency of these simulation methodologies on the random number generator is one of the items affecting the accuracy of the simultion result; therefore, an attempt has been made to investigate the issue. This note presents the observed sensitivity of random number sets in repetitive simulations of Gaussian and non-Gaussian wind pressures.

건축디자인을 평가하는 방법에는 상당히 맡은 요소를 고려 할 수 있다. 기능성, 구조성, 형태, 환경 등 다양한 요소를 고려하여 최종의 디자인을 생산해 낸다. 여기서 computer와 같은 자동화된 기계에 의해서 디자인이 생성된다면, 그 결과는 경우에 따라서 무수히 맡아 우리 인간의 평가 능력 범위를 넘는 수 가 있다. 따라서 디자인을 자동으로 생산할 뿐 만 아니라 자동으로 최선의 결과물을 자동적으로 평가하여 선택하는 것도 상당히 중요하다. 본 논문에서는 상기에서 언급한 요소 중 미학적 특성을 기계가 자동으로 평가하여 최적의 결과물을 선택할 수 있도록 평가 방법을 제시하였다. 평가 방법은 고전적으로 내려오는 미적 평가방법의 하나인 질서와 무질서의 상관 관계를 측정하는 것으로 이는 형태요소와 공간관계를 나타내는 형태 디자인 지식의 스키마적 표현을 적용한다.
