본 논문에서는 국내 지진발생 시 비보강 조적조 건축물의 손상상태 예측 및 내진성능 평가를 위해 기존건축물을 대상으로 역량스펙트럼 해석을 수행하였다. 이는 지진피해를 보다 상세하게 예측하고 건축물의 거동을 파악하기 위한 방법으로 국내 설계 지진하중과 부재의 비선형 특성을 적용하여 해석을 수행하였으며 해석 결과는 구조물의 손상상태에 따라 Slight, Moderate, Extensive, Complete 등으로 구분하여 평가하였다. 그 결과 대부분의 건축물에서 약간의 구조적 피해(Slight)와 보통의 구조적 피해(Moderate) 정도로 나타났으며, 일부 건축물에서 심각한 구조적 피해(Extensive)가 발생하는 것으로 예측되었다. 이전 연구에서 비보강 조적조 건축물의 내진성능평가를 위해 구조내진판정지표를 사용하여 내진성능을 판정하였으며 대부분의 비보강 조적조 건축물이 내진성능을 만족하지 못하였다. 본 연구에서는 기존 건축물에 구조내진 판정지표를 적용하고 그 결과를 바탕으로 역량스펙트럼 해석을 함에 따라 보다 상세한 구조물의 피해정도를 예측할 수 있었다.

In this study, neighborhood facility and office building to target two cases were performed BIM process. In the initial design phase of the planning process was conducted for the BIM process modeling, BIM in the design stage while performing the required range and level of the process were studied. Accordingly, from architectural firms to leverage BIM process, the proposed methods, efficient use of the modeling process proposed. Quality management information and input for the modeling and design process should be determined from the initial design and construction, including, for each field should be considered BIM, which require an appropriate range of information, according to these requirements, BIM creation and expansion of the level of information should be clearly defined. Perform the procedure for BIM in the process of communicating with stakeholders is critical. In addition, the input data and output data needed to perform management and to perform at the level obtained BIM design process and the model should be clear.

Ever since the local interior and architecture design industry adopted Digital fabrication modeling tool for its design operation in early 1990's, working environment has been changing. The Purpose of study is to analyze the digital Architecture fabrication modeling for digital design education in academy course. Digital Design Tools, Digital Space and Form, Digital Materiality and Digital Production. The Digital fabrication modeling is and important role in a traditional design process and digital design process. It is comprised of digital input devices(3D digitizer, 3D design tools) and digital output devices(cutting plotters, laser cut, CNC machines, 3D printers). Digital input devices can be shift a traditional design process to digital design process. Digital output devices are the principle of digital fabrication by CAD/CAM. Also, the result of this study provide the fundamental data for physical resources and digital design curriculum in KAAB.

The purpose of this study is to suggest a model for evaluation of a risk based value index for modular design alternatives in plant construction projects. Accordingly, 1) Setting the basic project cost and the scope to apply the module, 2) Evaluating the importance, easiness, and effectiveness index for Engineering, Procurement, Fabrication, transportation, and construction work, 3) Estimating the total project cost by analyzing the risk reserve Step, 4) Comparing the effectiveness index and total project cost for each modular design alternative, it was composed of the steps of deriving RVI. To verify such a model, Plan-A, which applied a module to one process, and Plan-B, which applied a module to three processes, were composed to evaluate RVI.

성능에 기초한 내진설계에서는 구조물이 보유하고 있는 능력을 효과적으로 파악하기 위해서 비선형 정적 해석이 적용되고 있다. 그러나 비선형 정적해석은 고차모드에 대한 효과를 고려하지 못함으로써 고층구조물이나 비정형 구조물과 같은 경우에는 정확한 비선형 지진응답의 산정과 내진성능을 평가하는데 문제점을 가지고 있다. 본 연구에서는 건축구조물의 선형 및 비선형 지진응답 평가를 위하여 응답 스펙트럼해석을 통하여 얻어지는 층전단력으로부터 층하중을 산정하는 유사동적해석법이 적용되었다. 제안된 방법을 비선형 정적 해석에 적용하여 구조물의 비선형 자동응답을 비선형 시간이력해석의 결과와 비교하였다. 기존의 층분포하중에 의한 비선형 지진응답과 비교하였으며, 제안된 방법에 의한 지진 응답이 구조물의 비선형 거동특성을 가장 정확하게 표현하였다. 그러므로 본 연구에서 제안된 방법을 사용하여 비선형 정적 해석을 수행한다면 비교적 명확한 건축물의 비선형 거동특성과 내진성능을 평가할 수 있을 것으로 판단된다.

This study aims to find out how architectural designers applied the design process and what content is applied in the practical process of architectural design in Korea, and to improve it if there is a problem. So the study is carried out by investigating 13 architects(Including one person who wants to keep his work private) with extensive experience in architectural design. The architects were questioned on how and what content the design process was used for their representative works that had been designed. And interviews and field surveys were conducted on other matters to be improved. The survey was conducted from November 2021 to July 2022. According to the conclusion of this study, First, Most architects were applying the design process in the architectural design practice. These are caused by an impact on education, but there was also an aspect of preparation in terms of guidelines such as the Architects Association and storage rights. Second, Although the design process differed in each name and phase, it was generally carried out in the order of the start phase, the planning work phase, the basic design phase, the intermediate design phase, the implementation quarterly, and construction. Third, The step-by-step work of the design process differed slightly depending on the architect, but counseling and contract work were mainly performed at the start-up phase, and field surveys, legal investigations, and case studys were conducted at the planning phase. In the basic design phase, some contents related to architectural programming, basic drawings, images, and models were used as main work contents. In the intermediate design phase, secondary contents such as licensed books and facility facilities were the main tasks. In the implementation design phase, detailed maps and various frost facilities were finally inspected. Since then, construction and supervision have been carried out in the order of progress. Forth, As for the contents to be improved in the future, the architect's ability, the designer's knowledge of the overall architecture, the design supervision system, and the expansion of time for the initial design process were answered.

The curtain wall engineering of local high-rise buildings consists of many phases such as design, curtain wail design, manufacture, procurement, construction and facility management, each of which also involves many' actors such as architect, curtain wall consultants, manufacturers, contractors, and facility managers. Moreover, the method for controlling the C/W process of each participant is needed. Eliminating wastes and problems existed in the C/W process can be more effective. What is more, it is necessary to improve the efficiency of the current process and to strengthen the competence through application of SCM to the C/W life-cycle. In addition, it is important that a ]ot of information transfer smoothly and share through information system. Therefore, this study aimed to propose the scope of application and the improvement directions in applying Supply Chain Management concept.

Barrier-free design reflects the attention of the disadvantaged groups. As a populous country with the largest population and the largest number of elderly people, China has made great progress in the field of the Barrier-free. The scope of this thesis is from the 1980s to 2012 in China, studying the development process of China's barrier-free design standards by comparing the two barrier-free design standards implemented in the history of such design. In this paper, the two standards are compared and analyzed in the following aspects, which are the numbering, chapters, scope of application, applicable objects and purposes, and so on. Compared with the 2001 barrier-free design standards, the 2012 one can be concluded that the development of barrier-free design in China has been accelerated, the scope of application has been widened than before, the content has been supplemented, and restrictions on terms have been reduced.

Use of high-strength steel members in building of high-rise buildings and large scale structures is expected to increase the effectiveness of structural design by reducing the weight and cost of structures. So far, high-strength steel members have been used in a very limited way because it is hard to select the proper strengths of steel members in a systematic way with the consideration of the structural cost. In this paper, therefore, a structural optimization technique based on Genetic algorithm is developed for effective use of high-strength steel members in structural design of high-rise buildings with the form of building frame system. The stability and efficiency of the technique is evaluated by using to a 35-story building. As a result, a stable and reliable optimal solution was obtained with a difference of 2.63% between individual and mean optimal structural costs.
