Filter by Keyword12 report(s) found with finite element method in the keywords field Several approaches are presented that allow for a direct path of image-to-analysis for the mechanics of structures using a combination of structure-from-motion (SFM) and the finite element method. Through these methods, conventional computational methods can be applied to models created from digital... The objective of this study was to simulate the stress-displacement behavior of a flexible debris-flow mitigation structure with a three-dimensional finite element model (FEM). Flexible, steel ring-net structures are becoming state-of-practice for debris-flow mitigation in mountainous terrain. These... In order to predict the functionality of transportation networks following a seismic event, performance of embankments under real ground motions needs to be well understood. Understanding of such performance can be realized using experimental testing or finite element analysis. This study aims to add... Steel bridges with reinforced concrete substructures and steel superstructures are considered to have superior performance under earthquakes when compared with their reinforced concrete counterpart. Such performance reputation stems from the fact that few steel bridges have been subjected to strong ground... Bridge expansion joints are a particularly troublesome component of bridges and many departments of transportation (DOTs) are looking for a solution to deteriorating expansion joints on highway bridges. Bridge expansion joints create a break in the structural continuity of a bridge, allowing clogging... Of all microelectromechanical systems (MEMS), regardless of application, micron-scale spacing of interleaved electrodes and high-dielectric ceramics in multilayer ceramic capacitors (MLCCs) provide exceptionally high capacitances in small volumes. This has led to MLCCs being the preferred type of capacitor... Crashes of heavy trucks with bridge columns are random events with low probability of occurrence. In spite of the low odds, previous collision events have resulted in catastrophic partial or full collapse of bridges. AASHTO-LRFD Bridge Design Specifications requires bridge columns to be designed for... Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with... The South Dakota Department of Transportation (SDDOT) currently has a Finite-Element Surface-Water Modeling System for Two-Dimensional Flow (FESWMS-2DH) and Research Management Associates 2 (RMA2) Both programs have the capability to model two-dimensional (2D) flow around structures. The department must... The objective of this project is to find effective configurations for using buckling restrained braces (BRBs) in both skewed and curved bridges for reducing the effects of strong earthquakes. Verification is performed by numerical simulation using analytical models of existing bridges when BRBs are implemented... |
