Abstract: Determination of overall factor of safety of a design involves repeated calculation of factor of safety at critical points in the design. For a given stress state at a point, the factor of ...

Abstract: A flexible algorithm for solving nonlinear engineering design optimization problems involving zero-one, discrete, and continuous variables is presented. The algorithm restricts its search only to ...

Abstract: The elastic solution of an orthotropic composite beam under the influence of uniformly distributed loading is obtained numerically. Two ends of the beam are rigidly fixed, and the fibers are oriented along and perpendicular ...

Abstract: The present research investigates the use of Fe-based shape memory alloy (SMA) strips for seismic retrofitting of rehabilitated RC bridge pier models. Four severely damaged bridge pier models were first rehabilitated by ...

Abstract: This study explored a new scheme for active confinement of concrete using cost-effective Fe-shape memory alloy (Fe-SMA) strips as an alternative to the expensive NiTi-based SMAs. The axial stress–strain behavior of concrete ...

Abstract: In water distribution systems, valves play a crucial role in system reliability and security by providing a shutoff function when it is necessary to isolate subsystems. In this paper failure of shutoff valves to close is ...

Abstract: HYDRUS (2D/3D) model was used to simulate spatial and temporal distributions of nitrate-nitrogen (
