Externally bonding steel plates is a common method for strengthening old bridges. Structural features and diseases of T-beam bridge are described. The project Erdao River Bridge was taken as an example. Based on static load test, changes deflection stress studied at the bottom RC T-beams strengthened by externally in loading process. Numerical simulation also carried out. results test show that...

The transmission of vibration to the adjacent buildings due to the traffic passing over Ghalemorghi Bridge in Tehran. has caused disruption to the inhabitants of the buildings. In order to investigate the vibration condition of the bridge, a dynamic loading test was performed and the output was analyzed using a non-parametric modal identification approach. In this article, the non-parametric mo...

We discuss the conductance of a molecular bridge between mesoscopic electrodes supporting low-dimensional transport and bearing an internal structure. As an example for such nanoelectrodes we assume semi-infinite (carbon) nanotubes. In the Landauer scattering matrix approach, we show that the conductance of this hybrid is very sensitive to the geometry of the contact, unlike the usual behavior ...

This paper describes a new material, polyurethane-cement composite (PUC), used to strengthen a 29-year-old reinforced T-beam bridge in Harbin, China. Polyurethane-cement composite (PUC) is mixed with polyurethane raw material and cement. This technique is completed by pouring Polyurethane-cement composite (PUC) into the template. Ultimate bearing capacity of the bridge after reinforcement was d...

We have synthesized rigid analogues of combretastatin bearing a furan ring in place of the olefinic bridge. These compounds are cytotoxic at nanomolar concentrations in neuroblastoma cells, display a similar structure-activity relationship compared to combretastatin A4, and inhibit tubulin polymerization. We also show that the furan ring can be further functionalized. Thus, it is possible that ...

We report the results from a sentencealignment experiment on DanishBulgarian and English-Bulgarian parallel texts applying a method based in part on linguistic motivations as implemented in the TCA2 aligner. Since the presence of cognates has a bearing on the alignment score of candidate sentences we attempt to bridge the gap between source and target languages by transliteration of the Bulgari...

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...

Bridge expansion joints (BEJs) are equipped at the girder end of long-span railway bridges to ensure reliable transition track. BEJs should have suitable dynamic stiffness running safety and stability vehicle. To explore influence vertical on response vehicle, track, bridge, a three-dimensional vehicle-track-bridge coupled model is established, sleeper spacing vehicle speed taken into considera...
