University facilities have became aged building because their average was more than 30 years old. The physical condition of the university facility is significantly correlated with student academic performance and outcome. Thus, green remodeling is crucial which improves energy performances of university facilities and student outcome. This study analyzes the case of 'H university'. Target of case study applies Green-Remodeling in old university facility for performance improvement. Goal of this study is suggestion for strategies to successfully apply Green-Remodeling to a university facility. This study draws a conclusion from risk analysis of the target case.

Membrane structure is a system that is stabilized by maintaining a tensile state of the membrane material that originally cannot resist the bending or pressure. Also, it is a system that allows the whole membrane structure to bear external loads caused by wind or precipitation such as snow, rain and etc. Tension relaxation phenomenon can transpire to the tension that is introduced to the fabric over time, due to the innate characteristics of the membrane material. Thus, it is important to accurately understand the size of the membrane tension after the completion of the structures, for maintenance and management purposes. The authors of this paper developed the new portable measurement equipment by using sound wave and measured the tension of pre-existing membrane structure for its maintenance by using the equipment. Through analyzing the measurement data, the authors propose the points that should be improved and the technical method for the new maintenance system of membrane tension.

When attaching the building exterior, builder used welded-building hardware in general. But it caused variety accidents like fires and explosions. Thus in this study, we developed the building hardware that not use welding and can follow the structures horizontal displacement when an earthquake occurs in the load building. And shaking table test was conducted.

Recently, the importance about safety diagnostics of structures has been increasing in proportion to construction accidents due to deterioration. In this study, with comparing and analyzing the status of safety diagnosis of domestic and overseas concrete structure, the purpose is to point out the problems of domestic concrete structure’s safety diagnostics using the nondestructive and propose the needs for improvement.

본 연구의 목적은 비선형 동적해석을 통한 국내 비보강 조적조의 내진성능을 평가하는데 있다. 보다 정밀한 내진성능 평가를 위해 조적벽체의 파괴모드를 고려한 비선형 이력모델을 이용하고자 하나, 선행연구의 비선형 이력모델은 정적반복가력해석에 대한 검증만이 수행 되었다. 이에 본 연구에서는 진동대실험과 동적해석 결과를 비교하여 제안한 비보강 조적조 비선형 해석모델의 신뢰성을 검증한 다음, 국내 비 보강 조적조 건축물의 비선형 동적해석을 수행하고 결과를 분석하여 내진성능을 평가하였다. 그 결과, 1층의 조적조 건축물의 경우 개구부율 에 관계없이 비교적 지진피해가 작은 반면, 2층 이상의 국내 비보강 조적조 건축물의 대부분이 국내에 발생가능한 지진에 취약하였다.

Structural engineers needs know-how about using nonlinear analysis softwares for seismic performance evaluation of existing building. In this study, it’s compared with several softwares, nonlinear analysis are available.

In Korea, Small-size buildings are not performed structural calculation. Also it does not assess the safety about lateral loads such like earthquake. In this study, We proposed the steel column bases that can be applied to small buildings. And We analyzed the Steel Column Bases flexural behavior.

This study compares the steel column-base plate connections to improve the flexural capacity of small building. In addition, performance level was evaluated by example building. Analysis results, an additional reinforcement is required to the proposed steel column-base plate connection. And then, We should compared the impact of beam-column joints.

To improve the wet process of concrete core wall, which is one of lateral load resisting system in high-rise modular building, the new composite panel system is developed and its structural performance under lateral load is investigated analytically.

In this study, the heat insulating performance increase the indoor temperature of the building is applied to the concrete was compared with plain concrete. As a result, the indoor surface at the outside temperature of 10.4 ~ 22.4 ℃ temperature conditions showed a difference of up to 0.6 ℃, the lowest 0.6 ℃, indoor temperature is up to 0.2 ℃, 0.2 ℃ lower results showed a minimum.

최근 국내 대표적인 플로팅건축물인 세빛섬의 운영 정상화로 플로팅건축물에 대한 이미지가 매우 긍정적인 방향으로 개선되었다. 플로팅건축의 특장점은 특별한 공간체험(29.9%) > 랜드마크(27.6%) > 수해양문화 향유(21.5%) > 관광 및 개발의 거점(16.0%) > 지구온난화 에 대비하는 친환경성(4.8%) 순으로 나타났다. 플로팅건축물은 일반인들에게 특별한 공간체험을 제공하며 차별화된 이미지를 가지고 있다. 따라서 플로팅건축물의 공간디자인마케팅은 특별한 공간을 매개로 지자체나 기업이 주민이나 고객들과 아이덴티티와 이미지를 교환하는 형 태로 일어난다. 이때, 건축물이 지닌 기본적인 공간 속성에 방문객들의 공간수요를 반영한 프로그램 선정과 사업주체 및 운영주체의 일원화가 중요하다. 플로팅건축의 프로그램은 상업시설이나 문화시설, 친수공간 확보 조건을 활용한 마리나시설이 적절하며, 향후 플로팅건축 시장도 활성화될 것으로 전망된다.
