Constructing deep underground tunnels faces severe challenges when the surrounding rock contains weak, unstable layers. This study investigates how the angle and spacing of these weak layers lead to the deformation and collapse of deep tunnel structures. A particle flow simulation, based on a 1,000–m-deep tunnel, was developed to recreate the physical behavior of the surrounding rock and observe …

As NASA pushes to build a sustained human presence on the moon, one expert says what's needed is a lunar building code.

Norway will start building the first full-size ship tunnel in the world next year after the government allocated NOK 8.6bn (£671m) in its budget for the long-delayed project. The Stad Ship Tunnel project will allow coastal ferries and small passenger ships to bypass the Stad peninsula in Norway’s Vestland county for the first time. The Stad peninsula is considered to be one of the most dangerous …

Canadian officials find structural defects in material used for hull and say firm failed to fully test ‘novel’ design Canadian safety officials have issued a damning report on the catastrophic final voyage of the Titan submersible, finding that the US company behind the expedition was overcome by “groupthink” and “confirmation bias” and failed to understand the profound risks confronting their la…

Flash floods are constantly shaping Texas communities and while efforts to keep residents safe are a priority, the shifting landscape is forcing urban planners and experts to think differently about how to plan for the next big storm. Mario Giacomoni, PhD, professor of civil and environmental engineering, and construction management, studies stormwater management systems and […] The post Podcast:…

Electric vehicles are central to the clean-energy transition, but the way their batteries are sourced and manufactured still carries a sizable environmental footprint. Research from Annick Anctil, associate professor in the Department of Civil and Environmental Engineering at Michigan State, shows that decisions about reshoring and friendshoring the battery supply chain can meaningfully shift tha…

Porto is a city that seems engineered for wonder. Its steep cobbled streets tumble toward the Douro River, where tiled façades glow amber at sunset and old trams rattle past wine cellars older than many nations. Travelers arrive for the port wine, the melancholic strains of fado, and the dramatic riverfront skyline, but Porto’s true magic lies in the way history and industry intertwine. Few place…

A 26-story tower rose in just five days, using a construction method that looks almost unreal but is already being tested at scale.

In order to explore the stability failure mechanism of reinforced concrete pipes during jacking in soft soil stratum and the influencing laws of various factors, a method for determining the pipe instability considering the pipe-soil contact state, pipe deflection, jacking force, buoyancy and slurry pressure was proposed through theoretical analysis. The applicability of this method was verified …

Nearly 1,900 engineering and computer science students — 1,111 bachelor’s degree candidates on June 13 and 777 master’s and doctoral candidates on June 14 — walked across the stage to the applause of more than 11,000 family members and guests

A new foundation system employing in situ grouting of helical screw piles has recently been developed. The paper discusses design considerations, installation procedures and results of full scale field load tests. This study assessed axial static loading tests on single, double and triple helix helical piles under grouted and un-grouted conditions. The field study was conducted to investigate the…

In performance-based seismic design, controlled dissipation of earthquake energy without damage to primary structural members is of great importance. Rotational friction dampers (RFDs) are considered an effective solution due to their stable hysteretic behavior and high energy dissipation capacity. However, direct simulation of the nonlinear behavior of RFDs is difficult in conventional linear an…

Reinforced concrete (RC) bridges worldwide are increasingly vulnerable to seismic events and deterioration mechanisms, particularly reinforcement corrosion. This review paper examines the application of Fiber-Reinforced Polymer (FRP) composites as an innovative solution for seismic retrofitting of corrosion-damaged RC bridges. FRP materials offer exceptional properties including high strength-to-…

I know nothing about engineering. I just wanted to satisfy my curiosity. Here is a picture (an ASCII picture of a factory with a wedge-top roof and some smoke from the chimney). > ...

The Sydney Harbour Bridge Cycleway Ramp redefines access to one of Australia's most significant pieces of public infrastructure. For decades, the northern approach to the Bridge's cycleway ended in stairs, breaking one of the city's most iconic journeys. This project replaces that stair-only access with a safe, legible and fully accessible ramp, completing a long-missing link in Sydney's cycling …

Brief: A group of mixed-use buildings designed on the 2226 principle, without cooling, heating, or ventilation technology, is created for Aspern Seestadt, a new and developing Vienna neighborhood that combines sustainability, quality of life, and economic dynamism.
