Based on the investigations on the floor live load and resistance parameters of typical residential buildings,such as the material strength and dimension tolerance of structural members,the present reliability level of residential buildings is studied,and the structural reliability as the result of altering the value of floor live load and increasing load when the room is deco.
在对典型钢筋混凝土住宅结构楼面活荷载以及结构构件材料强度、几何参数等抗力参数调查的基础上,系统地研究了当前住宅结构的可靠性水平,分析了楼面活荷载取值标准对住宅结构可靠度的影响以及装修增加荷载对楼板可靠度的影响,得出了住宅结构钢筋混凝土受弯构件可靠度降低的主要原因。
The multistorey and high-rise residential buildings in Xi an and Baotou,added up to 105 residents,465 rooms are investigated in the paper,and a great quantity of residential floor live load data are expressed in terms of uniformly distributed loads with the average load in batten area and room area.
荷载的统计分析是研究住宅结构可靠度的重要基础,对西安和包头地区多层和中高层典型住宅的105个住户、469间房屋的楼面活荷载进行了系统的调查,利用进深板带面积平均荷载法和室面积平均荷载法将其等效为楼面均布荷载;应用数理统计方法,研究了典型住宅结构持久性楼面活荷载和临时性楼面活荷载的统计参数和概率分布;给出了设计基准期50 a和100 a时住宅结构楼面活荷载标准值的建议取值,并与现行荷载规范进行了比较分析。
