Reliability analysis and design criteria for static strength of spherical tanks
To address the reliability design challenges of steel spherical tanks when static strength and load distribution parameters are interval values
a set of reliability design criteria for spherical tanks based on the combination of probabilistic and non-probabilistic theories was established.
Methods
2
Firstly
by introducing set theory
a reliability index model was established when the strength distribution parameters were interval values. Then
various conditions
including hydraulic
gas pressure
and gas-liquid combination tests under both extreme and general requirements
as well as normal operation
were systematically analyzed. Finally
the reliable indicators
stress limiting coefficients and safety factors for yield and burst strength were derived based on the median diameter formula.
Results
2
The range of values for yield and burst strength coefficients that meet reliability requirements under various test and operational conditions are determined
and corresponding condition factors are given. The research results offer a quantitative reliability reference scheme for the static strength design of spherical tanks
enhancing the safety and rationality of the design.
