Abstract: A theoretical study is undertaken in this paper to investigate the influence of finite deflections on transversely loaded rigid‐perfectly plastic beams. The support conditions are specified through both variable rotational ...

Abstract: The shakedown analysis of elastoplastic plane frames with semirigid connections is considered within a framework of discrete models and piecewise linear yield surfaces. The formulation adopted is based on the classical ...

Abstract: A full‐time, 15‐week bridge engineering course has been planned and is being implemented at the University of New South Wales in Australia to upgrade the technical skills of some 60 mid‐career bridge design and construction ...

Abstract: The limit analysis of circular cylindrical shells under hydrostatic pressure is formulated as a mathematical programming problem using the static theorem of plasticity. The governing differential equilibrium equations and ...

Abstract: The limit analysis of a class of grillages consisting of essentially two main circular arc girders connected by a number of straight cross beams is formulated as a mathematical programming problem using the static or lower ...

Abstract: The shakedown analysis of plane elastoplastic grillage structures for which plasticity is affected by the combined action of bending moment and torsion is formulated using the static or lower bound Bleich‐Melan theorem. ...

Abstract: A finite element procedure developed for the study of fracture in concrete is extended for the simulation of tensile and/or shear fracture in masonry. Triangular units are grouped into rectangular zones mimicking brick ...

Abstract: A mathematical-programming (MP)-based approach is proposed to directly determine the two extreme [(1) minimum, and (2) maximum] bounds of some static response quantity for elastic structures subject to the simultaneous ...

Abstract: Dual systems consisting of two shear-flexural structures are often used in high-rise buildings. This paper presents a second-order analysis of such dual systems, in which closed-form solutions are derived for the lateral ...

Abstract: Large discrepancies exist among current classical theories for the in-plane buckling of arches that are subjected to a constant-directed radial load uniformly distributed around the arch axis. Discrepancies also exist ...
