Abstract: Improved empirical methods for the prediction of perforation of reinforced concrete barriers by missiles produced by turbine fracture are developed. Data from recent turbine missile tests and existing empirical methods of ...

Abstract: Piles in integral abutment bridges (jointless bridges) are subjected to lateral movement due to thermal expansion and contraction of the superstructure. The reduction in vertical load‐carrying capacity of the piles due to ...

Abstract: A nonlinear finite element model is developed to investigate the stability behavior of a novel type of structure, namely prestressed sandwich arch. A prestressed sandwich arch is formed by buckling its individual layers ...

Abstract: Prestressed arches with different cross‐sectional forms (tapered and prismatic) are investigated by formulating the problem as a two‐point nonlinear boundary‐value problem. The arches are subjected to a constant live load ...

Abstract: Stability of a newly proposed structural system, namely the prebuckled (prestressed) sandwich arch is investigated. Stability of prestressed elastica arches with sandwich or homogeneous sections are compared through a ...

Abstract: Symmetrical and asymmetrical buckling of a prestressed arch and its equivalent rigid arch framework are investigated using a nonlinear finite element model. A corotational formulation of a three‐dimensional beam element ...

Abstract: Symmetrical and asymmetrical buckling and postbuckling behavior of a special type of semi‐rigid, self‐erecting dome (the prestressed dome) is investigated using a nonlinear finite element model. A corotational formulation ...

Abstract: Buckling and postbuckling behavior of prestressed arches that make up the skeleton of a large‐size clear‐span prestressed dome under self‐weight are studied using centrifuge model testing and a nonlinear finite‐element ...

Abstract: AS part of probabilistic safety analysis, the risk of structural damage to critical components of a nuclear power power plant from accidentally generated turbine missiles has been evaluated. Perforation and scabbing modes ...
