Finite element (FE) model-based dynamic analysis has been widely used to predict the characteristics of civil structures. FE model updating method based on hybrid genetic algorithm, by combining algorithm and modified Nelder–Mead's simplex method, is presented improve bridge structures' model. An objective function formulated as a linear combination fitness functions natural frequencies, mode shapes static deflections using measurements analytical results update both stiffness mass...
Cyclic tests have been widely used in earthquake engineering to experimentally evaluate the strength and postyield response of structures. It is well known that lateral a structure can be significantly affected by presence axial load; thus, loads need correctly applied during ensure accuracy test results. In past, it was challenging task satisfy force boundary condition real time for axially stiff members. Therefore, majority cyclic were conducted slowly over an expanded scale, which did not...
Welded headed studs are used to connect steel girders and concrete slabs in composite bridges. However, environmental problems related welded shear connectors have been reported, including noise dust generation during the replacement demolition of damaged or worn slabs. To overcome these issues, demountable that enable easy must be developed. conventional bolted mainly use embedded nuts, which cannot structures such as bridges because initial slip occurs stiffness resistance strength...
Backgroud/objectives Allomyrina dichotoma larva (ADL), one of the many edible insects recognized as future food resources, has a range pharmacological activities. In previous study, an ADL extract (ADLE) reduced hepatic insulin resistance high-fat diet (HFD)-induced diabetic mice. On other hand, associated molecular mechanisms underlying pancreatic beta-cell dysfunction remain unclear. This study examined effects ADLE on palmitate-induced lipotoxicity in beta cell line rat origin, INS-1...
This paper deals with the hybrid structural test technique which has been introduced and studied currently in Korea. In this study, a Mini-MOST system was developed as part of NEES research modified improved to reduce total simulation time half original system. Using proposed together 2 dimensional small steel frame specimen, validity efficiency is investigated. Even though an alternative shaking table applied for long several countries, no attempt made compare it directly test. Therefore,...
이 연구는 다양한 보강상세를 갖는 CFRP(carbon fiber reinforced polymer)로 표면매립 보강된 철근콘크리트 보의 보강효과에 관한 실험연구이다. 표면매립공법의 보강효과를 분석하기 위해 실험변수로 CFRP 보강재의 단면형상, 보강량, 매립 개수 및 위치 등의 적용하여 총 14개의 실험체를 제작하였다. 실험 결과, 표면매립보강의 파괴모드는 보강재 단면형상에 상관없이 보강재와 충전재가 하나로 거동하는 부착파괴 파단을 보였고, 홈 간격에 따라 주변 콘크리트의 파괴면이 중첩되어 조기 부착파괴가 발생하는 것으로 나타났다. 등가 단면을 고려하여 부착상세를 개선한 기계적 맞물림(MI) 실험체의 기존 부착파괴에서 파단으로 개선되었고, 효율은 83%에서 100%로 향상되었다.
Namhae Bridge, completed in May 1973, connects Island with mainland Korea the province of Kyongsangnamdo. It is a three-span suspension bridge main span length 404 m, and side spans 128 m each. A geometric survey static loading test was carried out deck geometry obtained from compared intended original design. On other hand, long-term monitoring system for Bridge employed December 1996. The objective to monitor structural responses view identifying deterioration rate over long- term period....

1 Internal Medicine, 2 Pathology, Good Gang-An hospital, Busan, Korea Behcet disease is a multisystemic disorder characterized by chronic relapsing triple symptom complex of recurrent oral ulceration, genital and ocular inflammation. The onset rare in old age as whole colon i nvolvement. We recently saw 78-year-old female patient examined to have intestinal with diffuse ulcers. She was admitted due multiple ulcers, low abdominal pain, hematochezia. Colonoscopy showed well-demarcated, large,...
<p>A series of researches for the assessment existing infrastructures have been intensively carried out more than 10 years in Korea. The products will be eventually related to a new guideline or code. Some them are results obtained from joint work between Korean Concrete Institute (KCI) and Japan (JCI). contributed ISO standards ISO/FDIS 16311-2. KCI implemented concept into revised ‘<i>Design Code Structures</i>’ published 2012 JCI also developed <i>'Guideline...
<p>In this paper, the development of a spliced girder which is called ‘SegBeam’ introduced. SegBeam use ‘joint block’ composes splicing end part segment and made higher strength concrete than other segment. The joint block used for easy match casting resisting stress concentration during process with post tensioning. Also, enables to make variable length as fabricated in advance can be moved form To verify performance, full-scale load test 60m-long carried out. structural safety...
