［提要］ 结构荷载和抗力作为结构可靠性分析时的重要参数，直接影响着结构可靠性。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。

Abstract:Load and resistance are the significant parameters in the reliability analysis that affect the structural reliability level directly. 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 decorated is analyzed.The reasons why the reliability of reinforced concrete flexural member decrease are given.
Keywords:residential buildings； floor live load； resistance parameter； reliability analysis
