• New Bay Bridge span designed to endure major quake

    Twenty years ago a 250-ton section of the Bay Bridge fell into the water as a result of a 6.9 magnitude earthquake; the new bridge design will be able to withstand the largest plausible earthquake to occur within a 1,500-year period

  • Indonesian experts: Dense soil, light materials vital for sturdier buildings

    In the wake of last Wednesday’s devastating earthquake in Indonesia, experts call for more care in choosing sites for new buildings and communities; key factor: the stability of the soil; “If you build the foundation 20 to 30 meters deep, then you need very dense soil,” an expert said

  • U.S. government eyes University of Maine's bridge technology

    Researchers at the University of Maine developed a “bridge-in-a-backpack” technology — so called because of its light weight and the portability of its components; the bridge uses carbon-fiber tubes that are inflated, shaped into arches, and infused with resin before being moved into place

  • All-titanium campus bridge show way for defense industry

    University of Akron, Defense Metals Technology Center co-sponsor design contest for titanium pedestrian bridge on university’s campus; titanium is a strong, lightweight, virtually corrosion-proof (but expensive) metal; a high-profile venture demonstrating titanium’s feasibility in commercial infrastructure projects could spark greater demand and open new markets for titanium
    ‘Avant-garde’ all-titanium span could spur other projects - and cut Pentagon’s costs

  • New titanium alloys offer better IED protection

    Titanium deforms and retains damage from strong impacts and fast applied forces — such compression on the metal can happen when it is hit by bullets or explosives; metallurgy theory provides a greater understanding of the material at the atomic scale — an understanding which will lead to the production of more resilient titanium

  • Scientists develop self-healing surface material

    The human skin, when scratched or cut, heals quickly, in most cases leaving no trace of a scar after just a few days; German scientists develop surface material with similar qualities

  • Glass fibers can make a building sturdier

    Conventional means to reinforce concrete involve the use of steel bars; the use of fiber reinforced polymer (FRP) is emerging as a valuable option, owing to its natural resistance to corrosion, its high strength, light weight, transparency to electrical and magnetic fields and ease of manufacturing and installment

  • New fire-resistant coating materials developed

    Aussie researchers develop HIPS — Hybrid Inorganic Polymer System — coating; it can withstand temperatures of more than 1,000°C compared to current commercial coatings used on building materials and structures, which break down between 150-250°C

  • New bullet proof vests will be made from cement

    University of Leeds researchers say that vests made of cement would offer cost-effective level of protection for many people at risk; it should be good enough for people like security guards, reporters and aid workers who are worried about the odd pot shot being taken at them

  • Using cloth to protect military vehicles from RPGs

    British company shows a newly developed textile which is strong enough to protect battle-field vehicles from RPGs

  • DARPA looking for Genesis-style AI lifeforms

    DARPA has issued a solicitation for ideas about self-organizing Tetris AIs and smart-vat superlife on cards; the research organization appears to be seeking nothing less than the creation of artificial intelligent lifeforms

  • Pervious concrete may eliminate need for storm drains

    A Minnesota town experiments with a new concrete paving method that lets rainwater pass right through the street surface to prevent damaging runoff

  • Researchers find ways to slow down deformation of concrete

    Concrete is used in practically all forms of construction — buildings, bridges, tunnels, dams; trouble is, it deforms and crumbles over time; MIT researchers discover the reasons for the gradual deformation of concrete, a discovery which will lead to concrete infrastructures capable of lasting hundreds of years rather than tens

  • Building sturdier structures in hurricane-prone areas

    The hurricane season is upon us; an architecture professor offers tips on how to build — and how not to build — sturdier structures in hurricane-prone regions

  • Glass-based coating for reinforcement bars for sturdier infrastructure

    Researchers develop glass-based coating for reinforcement bars that helps prevent corrosion and strengthens the bond between steel and concrete; the material could help engineers build stronger bridges and increase the longevity of other steel-reinforced structures
