지난 회에서는 고층 주거 빌딩의 외피를 높이라는 주요 변수 및 이 변수의 함수를 통해 발생하는 파생적인 변수들을 통해 파라메트릭 모델로 구성해 나가는 과정을 살펴보았습니다. 이번 회에도 지난회와 같은 연장선상에서 디자인에 영향을 미치는 하나의 변수를 설정하고 이 변수를 통해 전체적인 디자인을 구성해 나가는 과정에 대하여 살펴볼까 합니다. 지난 회의 예와는 조금 다르게 이번 회의 예는 "변수화 된 모듈러"라는 비교적 친근한 컨셉에 더 가깝다고 할 수 있습니다. 저번 회의 고층 주거의 스킨은 다수의 레이어로 구성이 되었었고 각 레이어들이 해당 레이어 전역에 걸쳐 변수와 상관관계를 가지게 되며 이러한 상관관계가 각 레이어들별로 서로 다르게 정의 되므로 conceptual level에서의 변수와 물리적 형태의 상관관계가 눈에 쉽게 보이는 물리적인 모듈러로 구현된다기 보다는 그러한 conceptual level에서의 관계가 물리적 모듈러의 생성단계를 뛰어넘으며 결과적으로 눈에 보이는 모듈러의 생성을 하지 않았습니다. 이에 더해 개별의 레이어의 적층으로 인해 변수가 어떻게 디자인에 영향을 주는지 직관적으로 이해하기 힘들었을 수도 있을 것 같습니다. 그에 반해 이번 회에서 살펴볼 예는 파라메트릭 디자인이라고 사람들이 흔히 이야기 할 때의 전형에 조금 더 가깝다고 볼 수 있을 것 같습니다.

The purpose of this study is to find out how we can improve the Registered Cultural Properties System in order to preserve and utilize of modern buildings which have been damaged and destroyed. The main object of the Registered Cultural Properties System is to build the cultural properties preservation system. But nowadays, it is very difficult to preserve modern buildings in city areas because of the desire of development for the site. So we need to approach economically in order to compensate for Registered Cultural Properties System. In this study, I suggested 4 type of system to preserve modern buildings by economical and lawful approach.

This study is as skyscrapers are becoming increasingly taller, more constructors have decided the height alone cannot be a sufficient differentiator. As a result, atypical architecture is emerging as a new competitive factor. Also, it can be used for symbolizing the economic competitiveness of a country, city, or business through its form. Before the introduction of digital media, there was a discrepancy between the structure and form of a building and correcting this discrepancy required a separate structural medium. Since the late 1980s, however, digitally-based atypical form development began to be used experimentally, and, until the 2000s, it was used mostly for super-tall skyscrapers for offices or for industrial chimneys and communication towers. Since the 2000s, many global brand hotels and commercial and residential buildings have been built as super-tall skyscrapers, which shows the recent trend in architecture that is moving beyond the traditional limits. Complex atypical structure is formed and the formative characteristics of diagonal lines and curved surfaces, which are characteristics of atypical architecture, are created digitally. Therefore, it's goal is necessary to identify a new relationship between the structure and forms. According to the data of Council on Tall Buildings and Urban Habitat (CTBUH), 100-story and taller buildings were classified into typical, diagonal, curved, and segment types in order to define formative shapes of super-tall skyscrapers and provide a ground of the design process related to the initial formation of the concept. The purpose of this study was to identify the correlation between different forms for building atypical architectural shapes that are complex and diverse. The study results are presented as follows: Firstly, complex function follows convergence form characteristics. Secondly, fold has inside of architecture with repeat. Thirdly, as curve style which has pure twist, helix twist, and spiral twist. The findings in this study can be used as basic data for classifying and predicting trends of the future super-tall skyscrapers.

As apartments have been made into high-rise buildings, the residents in the buildings have become to enjoy the benefits. On the contrary, the users of buildings on the back have become to experience many problems in residential environments. This research studied on measures to improve height control systems focusing on the heights of apartments in order to figure out the impact of apartments on city scenery. This study concluded that, to solve these problems, a general system to control heights should be prepared to solve the problem of visual blocking and for apartment complexes or buildings in coastal areas, regulations for height controls suitable to them should be separately prepared thereby controlling systems related to height controls as a whole instead of those many different systems relating to heights.

Since the study of building performance design was first undertaken by Building Research Station in 1930s, the results of such study has been reported from many parts of the world, building construction codes and standards have been revised based on performance in advanced nations as well in Korea, and various performance certification systems are in operation. The purpose of this study is to build a database of performance certification systems to investigate the co-relationship of various test methods related to the same test items. As test methods for case study, we selected test methods involving collision of the human body. Through analysis of Critical fall height test of EN 1177 and Head Model test of JIS A 6519 about 8 species of floor test-bodies, it was found that there are limits of application in terms of the depth and strength of cushion. Furthermore, although the measured physical parameters are the same, when the co-relationship between test methods is uncertain, the various physical parameters may not be compatible with the results.

Recently, evacuation safety of a resident of building become the major concern, because building has been higher and more complicated. Buildings in Korea should install the natural smoke venting or mechanical smoke exhaust equipment according to the building law. The smoke control is the most important to guarantee the evacuation safety. This study evaluate the influence to the height and temperature of smoke layer by enlarging smoke vent size and operating sprinkler system using CFAST (Version 6). Smoke venting size is larger, the effect to height and temperature of smoke layer is increased in below 5 MW fire. But, the correlation of these is decreased in above 10 MW fire. The case that opened smoke vent and sprinklered are applied, life safety criteria are satisfied regardless of fire size. After design the fire scenario according to the service and size of building. Install the smoke vent suitable for the fire size and verify that by experiment or simulation.

This study aimed to find problems of nightscape of Anyang-si through examination of behavioral pattern at night and measurement of illumination and luminance in accordance with regional classification following 6 regional classifications on the basis of ur1xm characteristic of Anyang-si. Basic concept of nightscape creation was application of improvement plan with analysis of regional problems and creation of artistic value to enhance image of Anyang-si as a city of art. To obtain balance and unity of night illumination, concept of light zoning was applied to smooth-transform method by regions. Especially, right to view harmonized with surrounding scenery was secured through creating gradual skyline compatible with neighbor buildings using division of each buildings according to their heights. In addition, way to improvement of night lighting environment was proposed as to illumination, height, type of lamp and arrangement of street lights and furniture in accordance with regional characteristics.

In this study, the seismic strengthening technique considering the rocking behavior of the wall was developed. The rocking system rotates left and right around the vertical axis of the wall. The development system is a method of dissipating energy by installing a damper which was attached at a large displacement portion. The damper was made of a steel material, and the shape and height of the strut were selected as variables. Experimental results showed that in case of shorter strut make strength capacity increasement and in case of longer strut make deformation capacity increasement. As a result of comparing the abilities according to I and S type strut shapes, it was evaluated that S type has better seismic performance.

Recently, the number of super high-rise building projects have been increased after recovering from international financial crisis. In super high-rise building project, vertical lifting is critical to overall project productivity, due to its limited lifting equipments. Also for projects which buildings' height are higher than 400m, transfer operation in lifting is inevitable because of lifts' maximum lifting height. In transfer operation, setting a transfer floor is essential for saving lifting time of resources. In this research, using discrete event simulation modeling with AnyLogic 7.0 software and metaheuristic optimization with OptQuest software, the method of optimizing a transfer floor for workers during the morning peak time is proposed. Comparing to the result of the case which transfer floor is designated to the middle floor, setting optimized transfer floor significantly decrease the total lifting time of workers. By using proposed simulation and optimization tool, saving budget and time through increasing available working hour is expected.
