Abstract: The uncertainty of a continuous variable is estimated by the combination of the objective entropy, which is obtained from the statistics of a countable population, and the fuzzy entropy, which is a measure of imprecision ...

Abstract: The assessment of reliability for framed steel structures is approached by the determination of limit state surfaces in load space. Surfaces corresponding to initial yield, plastic hinge formation and mechanism formation ...

Abstract: A general instantaneous or tangential stiffness matrix for a plane frame member is presented. Expressions in the form of integral equations are developed for members having axial forces and arbitrary material properties, ...
