摘要
对大型超市(欧尚超市)楼面活荷载进行了调查,收集了大量的楼面活荷载资料。采用单位面积平均荷载法和进深板带面积平均荷载法分别将楼面持久性活荷载和楼面临时性活荷载等效为楼面均布荷载,给出了楼面持久性活荷载和楼面临时性活荷载的计算结果。利用数理统计方法,研究了大型超市楼面持久性活荷载和临时性活荷载的概率分布和统计参数,建立了设计基准期T=50年时楼面持久性活荷载和楼面临时性活荷载的概率分布模型,并确定了模型参数。在此基础上,提出了我国大型超市楼面活荷载标准值的建议取值。
A great number of floor live load data are gathered based on the investigation of Auchan supermarkets. Since live loads on floor are usually expressed in terms uniformly distributed loads for design purpose, the sustained live load and the transient live load on floor calculated respectively with the average load in unit area and in batten area. Making use of mathematical statistics analysis, probability distributions and statistical parameters of sustained and transient quality of supermarket floor live load is studied. Thereby the distributed models and parameters of the sustained live load and the transient live load on supermarket floor obtained at design reference period T = 50 years. Our country＇ s characteristic value of live load on supermarket floor is advanced.
