[摘要]從調(diào)查中原地區(qū)城鎮(zhèn)住宅樓面活荷載出發(fā),闡述了建立持久性及臨時(shí)性活荷載概率模型的過程。根據(jù)統(tǒng)計(jì)得到的房間單位面積的重量,按不同使用功能將房間分類,繪制各類房間荷載分布折線圖,根據(jù)折線圖形狀呈左偏態(tài)的特點(diǎn),假設(shè)統(tǒng)計(jì)荷載服從極值Ⅰ型分布,采用χ2檢驗(yàn)法對假設(shè)的分布進(jìn)行檢驗(yàn)。結(jié)果表明,各種情況下均沒有理由拒絕統(tǒng)計(jì)荷載服從極值Ⅰ型分布。給出了代表中原地區(qū)城鎮(zhèn)住宅樓面持久性活荷載和臨時(shí)性活荷載最大值的概率分布函數(shù)和統(tǒng)計(jì)參數(shù),對編制荷載新規(guī)范具有參考價(jià)值。

Abstract:From the survey of the floor live load of the residential building in towns of the Central Plains region, the probability model of the durable live load and the temporary live load is given. According to the weight in unit area and the different using functions of each apartment, some classifications can be derived and then the load distributing polygonal line figure of each apartment can be drawn. Due to the polygonal line figure taking on left-deflection, statistic loads are hypothesized submiting to extreme Ⅰ-type distribution. These hypothetical distributions are tested with χ2. The analysis results show that the statistic load isn′t rejected submiting to extreme Ⅰ-type distribution in each case. The probability distributing functions and statistical parameters of the maximum of the durable live load and the temporary live load are obtained. The results would be references in compiling the new specification.
