事務室 積載荷重의 等價等分布荷重에 관한 硏究 = A Study on the EUDL for Live Loads in Office Buildings

다국어 초록 (Multilingual Abstract)

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.
