積載荷重의 一時荷重 特性에 관한 硏究

趙炯槿 호남대학교 1992 호남대학교 학술논문집 Vol.13 No.-

Recently structural engineers have recognized the inherent random nature of loadings and materials as well as the imperfect safety evaluation. Consequently, such trends require that the reliability-based design criteria for the building may have to be incorporated into the current building design codes. In order to achieve th above objectives, a live loan model of the structures will be developed. Live load data were collected in a systematic manner from a survey of 9 office buildings located in Seoul. Using the collected floor live load survey data, the equivalent uniformly distributed loads (EUDL) of the sustained and transient live load is computed. Due to the upper tail regions in the loads of interest from a structural reliability aspect, that will be appropriate to use load combination of the lifetime maximum live loads. The ultimate goal of this study are to develop probabilistic live load models to analyze survey data of domestic office buildings and to suggest design live loads with influence areas and structural members.

현행 設計積載荷重은 室의 用途別 및 構造部材別 등을 고려하여 환산돈 等價等分布荷重을 사용하고 있는데, 비현실적으로 과도하게 부가되는 積載荷重을 피하기 위해 특히 高層建物의 기둥에서와 같이 각 층으로부터의 軸荷重이 누적되는 경우 현행 建築法規상 받치는 바닥의 수에 따라 즉 負荷面積이 增加함에 따라 積載荷重의 低減을 허용하고 있다. 본 연구에서는 1개 층의 바닥을 받치는 기둥의 軸荷重에 대해 積載荷重의 現場調査를 실시하여 분석한 荷重模型을 이용하여 고층기둥의 軸荷重 특성을 분석하였으며, 현행 建築物의 構造基準法規에 제시되어 있는 받치는 바닥의 수에 따른 積載荷重의 減少係數의 타당성을 검토하였다. Recently, structural reliability theory has arisen from the need to account for the inherent vaiability of nature as well as man-made loads, together with the uncertainties in the strength of structural members. Therfore, live load data were clooected in a systematic manner from a survey of office buildings in Korea. Using the sruvey data, the basic statistics and the equivalent uniformly distributed loads (EUDL) are computed for various structural members (such as slab, beam, column). The ultimate goal of this study is to compare the currently recommeneded live load reduction factor by supported floor numbers and those calculated from the live load survey data.

Structural reliability theory has arisen from the need to account for the in-herent variability of nature as well as man-made loads, together with theuncer-tainties in the strength of structural members. Such trends require that the reliability-based design criteria for the building may have to be incorporated into the current building design codes. Therefore a probabilistic model of the structures will be developed. In this study, live load survey data in domestic office building have been collected in a systematic manner. Using the live load survey data, the equivalent uniform-ly distributed loads (EUDL), which produce the same load effect as the actual spatially varying live load, have been computed for various structural members(such as slab, beam. column). The results have been examined to find probabilistic characteristies (mean, standard devation, coeffieient of variance, etc) and relationshi[ between influence area and load intensity. Based on the probabilistic load model obtained, the maximum of a combined live load during the design life have been estimated and compared with current design live loads. This study suggested some information of design live loads in office buildings with influence areas and structural members.

Recently, structural engineers have recognized the inherent random nature of loadings and materials as well as the imperfect safety evaluation. Based on the successful developments of reliability-based structural analysis and design, the design criteria of the probabilistic limit state concepts., such trends require that the reliability-based design criteria for the building may have to be incorporated into the current building design codes. In order to achieve the above objectives, a probabilistic model of the structures will be developed. For the first time in Korea, an extensive live load survey of an office building was conducted for this study. Live load data were collected in a systematic manner from a survey of 9 office buildings located in Seoul. Using the collected floor live load survey data, the basic statistics(mean, standard deviation, coefficient of variance, ets.), a histogram of the equivalent uniformly distributed loads (EUDL) is computed. Due to the upper tail regions in the loads of interest from a structural reliability aspect, it is appropriate to examine goodness-of fit test and to compare two common probability distri-bution : The lognormal and gamma. Then, the optimum probability distribution is selected. The ultimate goal of this study are to develop probabilistic live load models to analyze survey data of domestic office buildings and to suggest design live loads with influence areas and structural members.

Construction project is curtailed production because information network process within multidisciplinary isn't smooth. Therefore in this study, proposed the application method of construction information technology which is not insufficient about performance, cost, and material, construction process, documents, data filing etc. in the design and construction step.

1930년대 후반~1950년대 한국과 일본의 대중음악을 통해 본 제국의 기억과 망각

조형근 한국사회사학회 2017 사회와 역사 Vol.0 No.116

제국일본의 붕괴 후 한국과 일본은 뒤얽힌 과거와 단절하고 별개의 국민국가로서 문화적 정체성을 만들어가야 한다는 과제에 부딪혔다. 한국에서는 유행가 비판을 포함한 왜색일소운동과 새로운 국민가요운동이, 일본에서는 군국주의 음악문화와 단절하려는 시도들이 일어났다. 두 나라 모두에서 미국 대중음악의 영향이 밀어닥쳤다. 하지만 1930년대 말 이후의 대중음악의 양상은 단절되지 않고 지속되었다. 애상조의 유행가 장르는 여전히 인기를 끌었고, 대중음악의 사회적 목적성도 계속 강조되었으며, 노래는 전쟁에 봉사하거나 전쟁을 추억하는 매개로 기능했다. 제국일본의 팽창과 동반했던 이국 취향 노래도 여전히 유행했다. 1930년대 후반에서 1950 년대의 한국과 일본 대중음악에는 통시적 연속성과 공시적 동형성이 존재했다. 애상조의 유행가와 이국 환상의 노래들은 아시아태평양전쟁기에 시작되어 한국에서는 분단과 내전으로, 일본에서는 패전과 점령으로 이어진 비극적 현실에 대한두 국민의 자기 연민과 현실 도피 욕구에 부응했다. 하지만 그 의미에는 차이가보인다. 한국인의 자기 연민과 이국 환상이 압도적이고 가혹한 현실 앞에서의 무기력의 표현에 가까웠다면, 일본인의 그것은 가해자가 아니라 피해자로 자처하는 전략적 선택의 표현으로 보인다. After the collapse of imperial Japan, Korea and Japan had to break with their shared pasts and tried to build cultural identities as separate nation-states. While Korea launched its Anti-Japanese Culture Movement and the National Song Movement, which criticized Japanese style popular song genres, e.g., Trot, Japan focused on breaking away from its militaristic music culture. Although American popular music influenced the musical trends of both countries, the impact of popular music since the late 1930s lingered on persistently in the two countries. Korean Trot and Japanese Enka, which share musical origins and sensitivities, were still at the heart of popular music. Songs served as the instruments of propaganda during the Korean War and as memory of Japanese experiences during the Asia-Pacific War. Exotic songs which had been accompanied by the expansion of imperial Japan were still in popularity. From the late 1930s to the 1950s, diachronic continuity and synchronic homomorphism characterize the music of both countries. In Korea, the popularity of sorrowful Trot songs reflected a type of self-pity Korean people experienced through severe wars and finally the division of their country. Exotic songs offered fantasy, providing a momentary amnesia of their tragic realities. Although similar tendencies existed in Japan, Japanese songs exhibit subtle differences in sensitivities aimed at representing Japanese people as sorrowful victims as opposed to brutal persecutors.
