Abstract:
|
This paper contains a compilation of results from some 50 000 steel specimen tests and close to 5 000
measurements of the cross-sectional properties of rolled steel members. Based on the statistical
distribution of these properties the statistical distribution of the sectional capacity of such steel members is
evaluated using a numerical integration procedure. For standard structural steel members the variations of
the strength properties are reasonably well-known and may be used in reliability assessment methods for
the design of structures. However, it has been observed in many actual failures with steel structures that
the cause of such failures normally is one gross human error, rather than a combination of “normal”
variations in parameters affecting the actions and response of the structures. Another observation from
failures experienced with steel structures is that gross human errors in execution are more critical than
gross errors in the design process.
