1 Scope
This standard specifies the principles and methods for determining the design values of gauge and toothed connections based on the structural reliability theory, including
Standard material and tooth plate connection performance of the standard value determination method, the uncertainty of the data and statistical analysis methods, sub-coefficient calculation method.
This standard applies to light wood structure specifications and tooth plate connection performance design value to determine.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 1931 wood moisture content determination method
GB/T 1933 wood density measurement method
Test method for characteristic value of structural material used in structure

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Reliability
Structure within the prescribed time, under the conditions specified, the probability of completion of the intended function.
3.2 Reliability index
Quantitative indicators of structural reliability.
Note The relationship between the reliability index beta and the failure probability pf is beta = -Phi-1 (pf), where phi-1 () is the inverse of the standard normal distribution function.
3.3 Target Reliable Index [beta] targetreliabilityindex [beta]
The structure should reach a reliable indicator.
3.4 Probability distribution
The statistical law of the value of random variables is generally represented by probability density function or probability distribution function.
3.5 Statistical parameter
The probability distribution is used to represent the average level of random variable values and the degree of discrete digital features.
