Objective: This study aims to establish the relationship between college students" participation in sports clubs that affect how they adapt to college life and cope with stress. Method: Out of four college students in the competition, 80 questionnaires out of 700 respondents who responded to the survey were excluded from the data collection process. Therefore, 620 responses from actual studies used in this study were used for data processing. To verify the differences, T-test and ANOVA were performed, and correlation between each lower scale was performed. Result: sports club activity participation groups showed that they had a higher aspect of adapting to college life than non-participating groups, and that there was a significant correlation between factors in college life adaptation and stress response. In addition, the degree of participation in sports club activities has been shown to be significant in how people adapt to college life and cope with stress. Conclusion: Program development and government support should be made so that students can actively participate in physical activities and feel them directly through constant participation during college life, by promoting positive awareness of physical activities, encouraging more active participation and developing further development.

The purpose of this study is to propose a new design provisions for Reduced Beam Section with bolted web(RBS-B) connections for seismic applications at IMF system. According to the experiment results of RBS connections, the rotation capacity of RBS-B and RBS-W connections which were not occurred fracture at connection had more than 4 % rad. However, the rotation capacity of RBS-B connections which were occurred fracture at connection had less than 4% rad. As a number of parameters which are activated to plastic rotation capacity of RBS-B connections are existed variably, those were analyzed experimental connection data for relations between parameters and rotation capacity at first study. So dominating influence factor for rotation capacity of RBS-B connections were used for new design provision to applicate at IMF system. In this study, the new design provisions of RBS-B connections were proposed for seismic application at IMF system and excess probability of total rotation angle at 0.02 radians respectively 16%, 50%, 84% using dominated parameters, moment strength ratio at plastic capacity of RBS-B connection.

문기훈(Moon Ki-Hoon),정지은(Jung Ji-Eun),한상환(Han Sang-Whan) 대한건축학회 2007 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.27 No.1
The purpose of this study is to evaluate the seismic performance of frame which assumed to build with Welded Unreinforced Flange - Bolted web (WUF-B) connections and detailed in compliance with the FEMA 350 recommended seismic design criteria. In FEMA 350 these types of connections are only valid for Ordinary Moment Resisting Steel Frames (OMRSFs). For this purpose, based on test results, this study proposed analytical model for the Post-Northridge WUF-B connections having different panel zone strength ratios. Using the connection model, SAC Phase Ⅱ 3 and 9-story frames were modeled and analyzed. Maximum interstory drift ratio of each performance level (IO and CP) were investigated through Incremental Dynamic Analysis (IDA). Analysis results were compared with those of buildings with either Pre-Northridge connection and ductile connetions with no fracture. Analysis results showed that buildings with Post-Northrdge WUF-B connections provide superior strength and interstory drift ratio capacity than the buildings with Pre-Northridge WUF-B connections.
비내진설계된 기둥 부재의 외부 띠 형태 내진보강 공법 개발

외부 띠 형태 내진보강 공법은 기둥 띠철근의 거동과 유사하게 기둥의 전단내력 및 연성능력을 향상시키는 보강 공법이다. 비내진설계된 기둥 부재인 경우 지진 발생 시 전단내력 부족으로 인한 취성적인 파괴가 발생하게 되는데 이를 외부 띠형태 내진보강 공법으로 보강할 경우 전단내력 및 연성능력이 향상됨을 다수의 실험을 통해 검증되었다. 이러한 보강 기둥의 연성능력 향상은 기둥의 파괴모드를 전단파괴 모드에서 휨파괴 모드로 변환하면서 생기는 것 뿐 만 아니라 휨전단파괴가 발생하는 기둥에서도 연성능력이 향상됨을 확인하였다.
