Abstract: Through summingup, statisti al parameters of steel material property based on new odes and statisti al parameters of
geometry property of lightweight steel members are obtained. Testing datum of lightweight steel members in different state of for e is
roundly olle ted. To in orporate small samples belong to disperse olle tivity into larger samples, singlefa tor varian e analysis
are finished. Then indeterminate statisti al parameters of all sorts of omputation modes and resistan e statisti al parameters of
lightweight members are obtained. A ording to statisti al parameters of lightweight steel members and material oeffi ient by new
ode and China load statisti al parameters in the eighties of the 20th entury, reliability analysis of several kinds of typi al
lightweight steel members are done onsidering different bearing states, different liveload types and different liveload ratio, et .
and ontrast analysis are performed on reliability level of above situations. Eventually reliability of these members and influen e of
