Ground displacement or collapsed buildings caused by natural disasters can lead to explosions, injuries, and environmental catastrophes. Jie Gong integrated several remote-sensing technologies, data processing, and decision-support tools to help pipeline owners monitor assets post-disaster and assess increased risks.

The Manhattan Bridge carries almost 90,000 vehicles and 1,000 trains over the East River to and from Brooklyn. Engineers are concerned about cracks in some structural elements. This project will develop a unique SHM system so we can better monitor how extreme traffic loads are affecting crack growth and displacement.

The objectives of this study were to perform computer simulations of vehicle-curb and vehicle-berm impacts, to characterize the behavior of a wide range of vehicle types after such impacts, and to produce design and evaluation trajectory data for use by NJDOT engineers. The impact simulations performed involved a wide va… |

The primary objective of this work was to produce a simulated 4D drive-through of a portion of highway(I-280 through Newark, NJ) for which proposed traffic-generator signing had to be reviewed. A 4D visualization was produced that combined 3D geometry rendering with the time element. Using the simulated drive-through, re… |

This report pertains to a comprehensive study involving the use of recycled materials in Portland cement concrete. Three different materials were studied including crushed glass (CG), street sweepings (SS), and recycled concrete (RC). Blast furnace slag was also considered as a cementitious additive for enhancing the dur… |
