The objective of this research is to develop uncertainty-propagation            procedures for general-purpose finite-element (FE) codes.  The extended         codes will contain several options, with the user being able to:                specify which geometrical parameters, material properties, loads, and           other relevant environmental conditions are uncertain; choose a                 probabilistic model for each random variable or random function; select         the response variables (displacements, deformation, internal forces,            etc.), the probability distribution of which is to be calculated; and           control the method of uncertainty propagation.  There will be also              flexibility as to the representation of response uncertainty, e.g.,             second-moment versus full-distribution and total-uncertainty versus             separation of uncertainty into contributions from different sources             (loads, geometrical variables, etc.).  Stochastic-analysis options will         be implemented on the NONSAP-C code and illustrated through detailed            study of one problem:  creep and shrinkage deformation of prestressed           segmental bridges as a function of time.
