Abstract: Stochastic finite‐element based reliability analysis is used to examine the performance of the load and resistance factor design (LRFD) method for steel structures. The reliabilities of members in actual configurations are ...

Abstract: A stochastic structural optimization procedure using element‐level reliabilities as constraints is proposed here. The procedure is robust and efficient and closely resembles the practical approach used in design offices. ...

Abstract: An efficient and accurate algorithm is proposed to evaluate risk in the time domain for nonlinear structures subjected to short duration dynamic loadings, especially seismic loading. The algorithm is based on the stochastic ...

Abstract: A time domain system identification technique is proposed to estimate the stiffness and damping parameters, at the element level, of a structure excited by unknown or unmeasured input forces. The unknown input forces could ...

Abstract: An efficient stochastic finite element method is proposed for the reliability analysis of nonlinear frame structures using the first-order second-moment reliability method. The assumed stress-field approach is used in ...

Abstract: A finite element‐based time domain system identification procedure is proposed to evaluate existing large structural systems at the element level. The procedure does not need any information on the input excitation forces. ...
