Jeddah Tower has reached 100 floors and is on track to exceed 1,000 meters, becoming the tallest building ever constructed and the first to reach a full kilometer.
The investigation into the causes of the collapse in Minneapolis in August 2007 of the I-35W bridge required sifting through a vast amount of design, retroft, and maintenance data prior to initiating the complicated work of analyzing the condition and loading of the bridge at the time of collapse. A new forensic tool—forensic information modeling—was created to store all of these data, as well as the geometry, as a three-dimensional visual database, enabling the engineers to pinpoint possible trouble areas in need of further inquiry.
On the evening of August 13, 2011 the Temporary Ground-Supported Structure Used to Cover the Stage Area and Support Equipment in the Production of Outdoor Entertainment Events located over the Grandstand Stage at the Indiana State Fair (the ISF Structure) collapsed while the audience was waiting for the headline act to begin. The incident resulted in the death of seven individuals and a multitude of serious injuries.
The Transbay Transit Center (TTC) will be located in downtown San Francisco, California, and will serve 11 transportation systems including the future High Speed Rail. The proposed structure is 1,500 feet long, and consists of 6 stories, including below-grade trainbox and 5.4 acre rooftop park. Series of two-dimensional seismic soil-structure interaction (SSI) analyses were performed, including fully-coupled direct solution approach as well as substructuring approach. “Scattered” motions, soil springs and dashpots were developed at different locations along the structure.
In order for fuel cell vehicles to develop a widespread role in society, it is essential that hydrogen refuelling stations become established. For this to happen, there is a need to demonstrate the safety of the refuelling stations. The work described in this paper was carried out to provide experimental information on hydrogen outflow, dispersion and explosion behaviour. In the first phase, homogeneous hydrogen–air mixtures of a known concentration were introduced into an explosion chamber and the resulting flame speed and overpressures were measured.
