본 연구에서는 배경이론을 통해 근대건축물에 관한 일반적 사항을 고 찰하고 근대건축물 보존 및 활용에 관한 연구자료를 분석하여 조사대상 을 선정하고 분석요소를 도출하였다. 조사대상은 수도권에 분포한 근대 건축물 가운데 문화재로 등록되고 원형보존이 되어 2010년대 이후 문화 공간으로 활용되고 있는 대상으로 한정하였다. 공간의 재생을 통한 근대 건축물의 보존에 초점을 두어 당시 근대건축물의 건축적 특성과 디자인 요소들을 파악하고 특성 보존이 어떻게 이루어지고 있는지 살펴보고자 하였다. 근대건축물의 보존은 외관은 당시의 원형 그대로 보존하거나 복원하 는데 비해 내부는 건립당시의 모습 그대로 사용하기 보다는 당시 실내디 자인 요소를 부분 보존하면서 새로운 기능을 충족하기 위해 공간구성이 변한 모습을 알 수 있었다. 이는 공간의 내부적 요소가 현대적 기능을 수 용하기에는 구조의 노후화, 사용목적 및 환경의 변화 등의 문제점이 있 기 때문에 공간을 원형보존 한다는 것은 어려움이 따르나. 근대건축물의 보존은 쇠락한 건축물을 새로운 공간의 장으로 변화시켰다는 의미를 지 닌다. 현대건축물의 다양화, 고층화의 경향 속에서 새로운 문화적 공간 을 창출하였고 근대건축물 재이용의 다양한 방향을 제시하였다는 것에 의의를 갖고 있다. 종합해 보면 건축물을 다시 짓고 새로운 공간을 조성 하는 것보다 기존의 건축물을 재이용 하는 것이 더 큰 효용가치를 지닐 수 있고 문화적으로도 의미 있는 일이기 때문에 근대건축물의 보존을 위 한 다양한 재이용의 방안과 가치에 대하여 더 많은 연구가 필요하다고 본다.

As a plan for establishing Korea's cultural identity and its competitive edge in the world market and for enhancing Korea’s cultural status, creative and unique high value-added cultural products need to be developed utilizing our inherent cultural assets. Accordingly, this study focused on the development of the design of fashion cultural products that utilize the convergence of Hangeul our peculiar font style and Korea's cultural heritage, which is registered as part of UNESCO’s World Heritage. A design method was devised that converges archetypal images of cultural property with the unique Hangeul font in a way that targets Korea's symbolic architectures. The symbolic architecture includes Korea’s world-heritage pagoda architecture, such as Seokgatap pagoda and Dabotap pagoda at Bulguksa temple. It also included the architecture of royal palace, such as Injeongjeon hall at Changdeokgung palace. Finally, it also included the architecture of the fortress wall, such as Paldalmun gate in Hwaseong fortress. Thus, by developing cultural assets made from a convergence between architecture and the Hangeul font as a consumer-product image that has universality, the possibility of cultural products was pursued by applying color planning after an analysis that involved extracting the compositional colors of the flags of the world. This research and approach will lead to opportunities for further progress for Korea's cultural products in the global market as a results of additional recognition for their value, excellence, and universal appeal.

In contemporary society, vibration and noise in the road nearby buildings have become social problems as vehicles operation has increased. Especially, in the case of the building used to art performance, available suitability of the building is tested by the indoor noise class. Therefore, the purpose of this paper is the measurement of the structure-borne noise of Seoul Art Center nearby Umyeonsan tunnel and analyzing the effects of countermeasure to it. To measure the effects of countermeasure, not only structure-borne noise is measured, but also the vibration is measured, before and after the construction of pavement using pad and porous asphalt. Consequently, the sound pressure level in art center 1st floor is reduced after mat pavement method, structure-borne noise that was high in 25Hz wide-band before pavement decreased regardless of experimental vehicle's velocity. Using porous asphalt pavement the noise was reduced about 3 dB(A).

The retractable roof structure is used in various fields and it is classified for steel retractable system and soft retractable system. For the domestic industry, it is in the initial phase now and the demand of the retractable roof structure is expected to increase in the future. Therefore, this paper is classified for steel retractable system and soft retractable system from the retractable roof structures in overseas to survey and analyze the cases of wind velocity on retractable roof structure in Japan that uses the same wind velocity criteria like Korea regarding the open-close time and average open-close time for retractable roof area.

This study aims to establish a seismic resistance performance evaluation method that makes sure to secure the seismic resistance performance of the existing mid-low story reinforced concrete structures. This study focuses on the development of the seismic resistance performance evaluation method for the overall seismic resistance performance evaluation on the buildings by applying fuzzy theory. This seismic resistance performance evaluation method considers the mutual relations among the type of force, the type of member, the type of story, and the states of deterioration of the buildings. The total seismic resistance performance index from this method was calculated by the intensity weight of each evaluation item, fuzzy measure, fuzzy integration. Moreover, the evaluation methodology was established in this study to identify the performance level of the Immediate Occupancy, Life Safe, Collapse Prevention by applying the fuzzy theory.

In this paper, it is covered in detail the process of generating structural alternatives with geometry change and its optimization by StrAuto. The main roof structure of the Exhibition Center is modelled parametrically and the optimal alt is derived by observing volume changes according to geometry change of main roof truss. Existing studies performed optimization process through sections and properties due to the limitations of shape change, but this study have meaning of performing the optimization with geometry changes which is the most critical skills of StrAuto. By the process of securing a sufficient margin by geometry changes and reducing volume with the optimization of sections, despite of a partial optimization of large space structure, it could be reduced by 11.7% of the total volume.

Since 1995 the special act for safety management of public facilities have been enacted in Korea. Since then undergoing safety accidents great and small, legal system was revised several times for safety promotion. As part of its efforts Korea Infrastructure Safety & Technology Corporation have periodically evaluated the building safety inspection or diagnosis reports based on Special Act for Safety Control of Public Structures and published annual casebook. This study investigates and examines the cases of bad or poor reports until now. This paper aims at reasoning out the technical and institutional improvement plan for error-prone problems when safety inspection of buildings.

This study analyzed indoor and outdoor thermal performance among different types of green roofs and green walls in order to provide information for building greening. When temperature reduction effects of green roofs and green walls were compared to the control, the effects was highest at the green roof and wall treatment, followed by green wall, green roof, and the control, which means there was temperature reduction effects by building greening. Also these temperature reduction effects was influenced by outdoor weather condition such as being typically high in sunny days but not notable in rainy days. In addition temperature reduction was effective as the air temperature was up but was not influenced by wind velocity. As for directions, the west side showed the highest temperature followed by the south and east in the order. Heat flow was found greater in control than in green roof and green wall. In addition, heat flow reversal was found as time went on.

Nonlinear analysis for seismic performance evaluation of existing building usually takes 4~5 times more than linear analysis based on KBC code. To obtain accurate results from the nonlinear analysis, there are a lot of things to be considered for nonlinear analysis modeling. For example, reinforcing layout, applied load and seismic details affect behavior of structural members for the existing building. Engineer-oriented computerized system was developed for engineers to evaluate effective seismic performance of existing buildings with abiding by seismic design principles. Using the engineer-oriented program, seismic performance evaluation of reinforced concrete building was performed. Nonlinear hinge properties were applied with real time multiple consideration such as section layout, section analysis result, applied load and performance levels. As a result, the building was evaluated to satisfy LS(Life Safety) performance level. A comparison between engineer-oriented and program-oriented results is presented to show how important the role of structural engineer is for seismic performance evaluation of existing buildings.

Seismic analyses of a pile under a large rigid basement foundation embedded in the homogeneous soil layer were performed practically by a response displacement method assuming a sinusoidal wave form. However, it is hard to take into account the characteristics of a large mat foundation and a heterogeneous soil layer with the response displacement method. The response displacement method is relevant to the 2D problems for longitudinal structures such as tunnel, underground cave structure, etc., but might not be relevant with isolated foundations for building structures. In this study, seismic pile analysis by a pseudo 3D finite element method was carried out to compare numerical results with results of the response displacement method considering 3D characteristics of a foundation-soil system which is important for the building foundation analyses. Study results show that seismic analyses results of a response displacement method are similar to those of a pseudo 3D numerical method for stiff and dense soil layers, but they are too conservative for a soft soil layer inducing large soil pressures on the foundation wall and large pile displacements due to ignored foundation rigidity and resistance.

In this study, to estimate the combination of earthquake magnitude (Mw) and distance (R) corresponding to the design spectrum defined in Korean Building Code (KBC) 2016, the response spectra predicted from the attenuation relationships with the variation of Mw (5.0~7.0) and R (10~30km) are compared with the design spectrum in KBC 2016. Four attenuation relationships, which were developed based on local site characteristics and seismological parameters in Southern Korea and Eastern North America (ENA), are used. As a result, the scenario ground motions represented by the combinations of Mw and R corresponding to the design spectrum for Seoul defined in KBC 2016 are estimated as (1) when R =10 km, Mw = 6.2~6.7; (2) when R = 15 km, Mw = 6.5~6.9; and (3) when R = 20 km, Mw = 6.7~7.1.

바람이 불어오는 과정에서 지형 및 지물을 지나칠 경우 바람은 흐트러진다. 이 흐트러짐에 의해 풍속은 빨라질 수도 있고 느려질 수도 있다. 특히 건축물이 밀집되어 있는 도심지에서는 주로 속도가 느려지는 현상이 발생한다. 본 연구에서는 실물축척의 도심지를 재현하여 풍동실험을 통해 도심지에서의 차폐효과에 의한 풍속이 느려지는 현상을 정량적으로 평가하였다. 차폐효과에 큰 영향을 미칠 인자들을 도로폭과 주변건축물들의 평균적인 높이로 선정하였고 각각의 조건에 따른 차폐의 정도를 차폐계수로 정의하여 나타내었다. 연구의 결과로부터 도로방향으로 바람이 불 경우 왕복4차선 이하의 도로변에서의 차폐계수는 0.85 이하로 나타났고, 도로직 각방향으로 바람이 불 경우 왕복6차선 이하의 도로변에서의 차폐계수는 0.9 이하로 나타났다.
