Superstructure optimization of hybrid thermal desalination configurations
… structures. It is based on the notion of superstructure, which allows for the representation of numerous feed, brine and vapor routing schemes. A superstructure is developed. By adjusting the flow routings, the superstructure is capable of representing the common thermal desalination …

Synthesis, Superstructure, Vacancy-Ordering of Intercalated Transition Metal Dichalcogenides
… which then indicates the existence of a superstructure. An eightfold superstructure has been found for 6R-CuxTa1+yS2 (x = 0.237, y = 0; x = 0.23, y = 0.06) and a fourfold superstructure has been found for 2H-Cu0:52TaSe2. 2H-Cu0:16Ta1:08Se2 and Cu3TaSe4 do not form any superstructure.

Interval based MINLP superstructure synthesis of heat and mass exchange networks
… networks. The method involves generating superstructures using the temperature/composition interval concept from the physical insight approach. The superstructures are partitioned into temperature/composition intervals using the supply and target temperatures/compositions of either the …

Supply and target-based superstructure synthesis of heat and mass exchange networks
This study presents three new methods for superstructure synthesis of heat exchanger networks (HENs) and mass exchanger networks (MENs) that involve the use of key parameters in HEN and MEN to define superstructure intervals. The key parameters are the stream supply and target …

Characterization of the loading environment for shared-use railway superstructure in North America
… it is impossible to adequately evaluate the superstructure to make design improvements. Therefore, researchers at the University of Illinois at Urbana-Champaign (UIUC) are conducting research to lay the groundwork for an improved and thorough understanding of the loading environment entering …

Analysis of the design of railroad track superstructure components for rail transit applications
An extensive study of the performance of railroad superstructure in rail transit systems was conducted at the University of Illinois at Urbana-Champaign (UIUC) as part of a research program funded by the Federal Transit Administration (FTA). Focusing on field characterization of the performance of …

An economic evaluation on FRP for bridge construction in South African coastal areas
… cost analysis (LCCA) on two highway beam bridge superstructure designs: a SRC superstructure and a GFRP-RC superstructure to determine the preferred design, which was used to conclude on the economic viability of FRP in bridge construction. The deterministic approach to the LCCA was selected and …

Response of Continuous Steel I-Girder Bridges Subject to Temperature Variation
Thermal deformation of the superstructure in continuous slab-on-girder bridges must be freely permitted to avoid potential adverse behavior due to the development of thermal forces. The use of fixed and guided bearings can introduce a significant amount of restraint against thermal deformation …

Design and field testing of jointless bridges
… elimination of joints and bearings in the bridge superstructure. These joints and bearings are expensive in both initial and maintenance costs, and can get filled with debris, freeze up and fail in their task to allow expansion and contraction of the superstructure. They are also a "weak link" …

Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems
… the constant threat of these natural disasters. Superstructures can be washed away due to lateral forces generated by floodwater. Floodwater can also accelerate scouring around bridge piers, which often contributes to bridge failures. This research used the results of an extreme flood simulation …

Adjustable Frequency Bandgap for Seismic Vibration Isolation of MRE-Based Metamaterial Foundations
… structure's foundation, eventually damaging the superstructure. These seismic waves are more frequent in some areas because of their geological variations. The seismic vibration caused by earthquakes can damage the structure, leaving it unrectifiable and unusable. Different types of seismic …

Analysis of the AASHTO LFRD Horizontal Shear Strength Equation
… girder is essential to the optimization of the superstructure. The transfer of forces in the deck to the girders is done across a shear interface between the two elements. The transfer occurs through the cohesion of the concrete at the interface and then through the shear reinforcement across …
