Abstract: Reliability evaluation methods based on directional simulation for structural reliability analysis is treated herein. The methods can be used to check results obtained by a first‐ or second‐order reliability method. ...

Abstract: Reliability analysis of highly redundant ideal‐plastic structures is difficult due to the existence of a very large number of possible failure modes. If only some of the failure modes are identified and included in the ...

Abstract: The reliability with respect to plastic collapse of rigid frame and truss structures is estimated by directional simulation. This conditional expectation simulation method is especiahy attractive for this problem because ...

Abstract: New insight into parametric sensitivity in first-order reliability theory is given by studying the parametric sensitivity of the most likely failure point. A formula is derived for the derivative of the unit normal vector ...

Abstract: An adequate representation of model uncertainties is important for reliability analyses based on geotechnical analysis models of unknown credibility. A procedure is outlined for calibration of the probability distribution ...
