Qingzhou Channel Bridge section of HZMB The Hong Kong-Zhuhai-Macau Bridge (HZMB) is designed to have a lifespan 120 years. The mega-structure, which opened October 24, is built to withstand a magnitude 8 earthquake, a super typhoon and strikes by super-sized cargo vessels. However, the Pearl River Delta operational environment is one of the world’s most densely urbanized regions. Degradation and aging from the environment and operation, along with natural and man-made disasters, will impact the bridge’s structural [...]
New nuclear power generation is an important non-fossil fuel option to meet future global electricity demands. To ensure public safety and maintain energy security, the new reactors must be significantly safer and more efficient than previous designs. The Gen-IV design initiative is driving the development of the next generation nuclear plants with designs such as the Molten Salt Reactor, Sodium-cooled fast reactor, Lead-cooled fast reactor, very high temperature reactor and Supercritical-water cooled reactor. These reactors [...]

Last year a group from Los Alamos National Lab published two papers that detail experimental studies involving the use of a Micron Optics si155 optical sensing interrogator and Fiber Bragg Gratings (FBGs) in extreme sample environments. Some of these environments included cryogenic temperatures, large magnetic fields and applied hydrostatic pressures. The first paper titled, “An FBG Optical Approach to Thermal Expansion Measurements under Hydrostatic Pressure”, discusses an optical technique for measuring thermal expansion and magnetostriction [...]
The University of Florida recently completed a research study to develop improved analysis tools with the capability of analyzing the horizontal cracking potential under environmental and traffic loading conditions for concrete pavements using 3-D finite element modeling and to also create an effective instrumentation plan for the US-301 Concrete Test Road. Non-conventional concrete pavements including ductile concrete slabs made with reclaimed asphalt pavement (RAP), precast prestressed concrete pavement (PPCP), and continuously reinforced concrete pavement (CRCP) [...]
