  • This research describes how to predict a model of the tensile strain related to the fatigue cracking performance of several asphalt concrete structures through design of experiments(e.g., Response Surface Methodology) and harmony search(HS) algorithm. The axisymmetric analysis program of finite element method, which is the KICTPAVE, was used to determine the strain level at the interface layer between asphalt layer and lean concrete layer. Once the training database set of various strain levels was constructed under the several condition of layer stiffnesses and thicknesses in the asphalt concrete structures, the data set was trained through the HS algorithm in order to determine the regression coefficients defined based on a response surface methodology. Furthermore, the testing set, which was not used for the training procedure of HS algorithm, was also constructed in order to evaluate whether the regression coefficients of a prediction model can be appropriately applied for other cases in asphalt concrete structures.

  • A bunch of asphalt roads have been damaged frequently in relation to the rapid climate change. To solve and prevent this type of problems, many nationalities in the world have performed various researches. In this regard, the objective of this study is to develop prediction model as to the number of potholes occurred in seoul. At the same time, we have utilized empirical and statistical approaches in order for us to identify factors which is affecting the actual occurrence. The predictive model was determinded by using BHS (Basic Harmony Search) algorithm. Prediction was based on the weather and traffic data as well as data occurrence data of porthole. To assess the influences which are PAR(Pitch Adjusting Rate) and HMCR(Harmony Memory Considering Rate), we determined suitability by changing the values. In the process of the determining a predictive model, the predictive model composed Training data (2011, 2012 and 2013yrs data). To determine the suitability of the model, we have utilized Testing Set (2009 and 2010 yrs data). The suitability of the basic prediction model has been from RMSE(Root Mean Squared Error), MAE(Mean Absolute Error) and Coefficient of determination.

  • 지금까지 건조된 jacket 중에서 가장 큰 것으로 알려진 미국 Exxon사의 Harmony jacket 이 현재 현대 중공업에 의해 제작되고 있다. Harmony jacket은 제작완료 후 울산으로부터 미국 California서안의 Santaynez해역으로 운송될 예정인데, 이와 같이 긴 해상운송시에 jacket과 seafasening 부재들은 피로에 의하여 상당히 손상을 입을 수 있다. 본 연구에서는 두가지의 가능한 운송항로에 대해, jacket과 tie-down 부재가 받는 피로에 의한 손상정도를 계산하고 그 결과를 비교 하였다. 몇 가지 가정하에 행하여진 해석 결과에 따르면, 피로에 의한 손상을 적게 주는 운송항로는 Hawaii를 경유하는 남쪽할로이며, 운송 barge와 인접하는 부분, 특히 barge 양단 부근의 jacket joint들이 손상을 받기 쉽다는 것을 알 수 있다.

  • Berlin Philharmonic Concert Hall is one of most prominent architecture of Hans Scharoun, which is known as the fine combination of the functionalism as an important factor in modern architecture and the hi-developed technology Moreover, the plan and spatial planning of the concert hall is famous for its evolutionary approach compared to other traditional concert halls. The objective of this paper is to examine forms and organic system of functions of this concert hall in order to re-evaluate it's historical meanings in our modern architecture history, The current study will also look into how the personal background of Hans Scharoun has influenced his design in various ways, especially the inside of lobby and auditorium of Berlin Philharmonic Concert Hall.
