Seismic Performance of seat-type bridges with elastomeric bearings
In Iran and some other countries, elastomer bearings in seat-type bridges are used with no sole/masonry plates and there is no positive connection between superstructure and substructure. Different codes have diverse provisions regarding the coefficient of friction (μ) between elastomer bearing and superstructure/substructure and also the design strength of shear keys (Vsk). Developing a finite...
متن کاملSeismic Risk Assessment of Optimally Designed Highway Bridge Isolated by Ordinary Unbounded Elastomeric Bearings
Recent experimental research has shown that ordinary unbounded steel reinforced elastomeric bearings (SREBs) can be considered as an attractive cost-effective option for the seismic isolation of highway bridges. To further investigate its benefits, the current study is focused on the seismic risk assessment of an optimally designed highway bridge isolated by SREB system. A typical three-span hi...
متن کاملNumerical Analysis of Elastomeric Fluidic Microvalves
We present a finite element model of polydimethylsiloxane (PDMS) fluidic microvaJves. A valve is fabricated by assembling two patterned layers in a two-channel crossed architecture. The valve closes as a consequence of the motion of the intertayer membrane. The membrane is deformed by the pressure of the actuation fluid, flowing in one of the two channels. By using a soft rubber material model,...
متن کاملElastomeric PGS Scaffolds in Arterial Tissue Engineering
Cardiovascular disease is one of the leading cause of mortality in the US and especially, coronary artery disease increases with an aging population and increasing obesity. Currently, bypass surgery using autologous vessels, allografts, and synthetic grafts are known as a commonly used for arterial substitutes. However, these grafts have limited applications when an inner diameter of arteries i...
متن کاملModeling and Numerical Challenges in Nanoscale Device Engineering
In spite of considerable research effort and progress, high quality simulation-based design of nanoscale emerging devices still presents formidable modeling and computational challenges. Characterization of nanoscale emerging devices needs to be addressed via quantum simulations that need to account for: (i) information of the material at the atomistic level, (ii) multiscale aspects of electron...
