Two people are dead and up to 40 people were trapped on Tuesday afternoon when a section of a shopping mall under construction collapsed in South Africa. Construction workers were roughly half-way done with the three story mall when the second floor collapsed. Rescue workers arrived on scene to provide medical assistance to those who were injured and used sniffing dogs to find workers trapped in the rubble.

Devastating Tornado Leaves Path of Destruction

The storm system that swept across the Midwest on Sunday night left 8 people dead and thousands of people homeless.  The storm claimed 6 lives in Illinois and 2 in Michigan.  According to the Chicago Tribune, 81 tornadoes were sighted throughout the Midwest and many areas saw large amounts of hail. Washington, IL, one of the hardest hit areas by the storm, estimates that up to 500 homes were damaged in its community.  Many towns throughout the region saw similar damage.  Currently 7 counties in the state of Illinois are being considered disaster areas.

Old Bay Bridge Demolition Underway

Workers began tearing down the east span of the old Bay Bridge on Tuesday, nearly two months after the new bridge opened.  The demolition of the old bridge is expected to be a long, tedious process.  Construction workers will have to dismantle the bridge piece by piece.  According to one of the California Department of Transportation’s bridge engineers,  “the old bridge is the world’s largest armed bow and arrow. We have to de-string it very carefully or it will go boom.”  The $281 million demolition project is expected to take three years to complete.  This cost was already incorporated into the $6.4 billion price tag for the new bridge.  The 1.97 mile long east span opened in 1936 and is made of almost 59,000 tons of steel and 245,000 tons of concrete.  The majority of the steel will be recycled or reused, but some will be saved for a new park commemorating the old bridge.  The following link contains a great slideshow of construction crews beginning the demolition of  the bridge.

The Council on Tall Buildings and Urban Habitat announced Tuesday that One World Trade Center is now the tallest building in the United States, at 1,776 feet tall. Previously the tallest building honor went to the Willis tower in Chicago, IL, which stands 1,451 feet tall. The debated issue was whether or not the mast atop the new WTC building should be counted toward the architectural height. The council decided that since the 408 foot spire is a permanent architectural fixture, and not used for technical purposes, its length would be added to the total height of the building, therefore making it taller than the Willis Tower.

TheStructuralEngineer.info is pleased to announce the launch of its First Interactive GeoSoftware Database! You can find it online at http://www.thestructuralengineer.info/software-home. Our goal is to create the most comprehensive database for structural engineering software worldwide. This new database is a major upgrade of our previous database that was already very popular. However, the new one has dramatically improved features and its content is growing daily. It already includes 46 software in 8 categories listed, and new are added each day!

Frequency Response Analysis with DIANA Featured

The dynamic analysis of dam-fluid-foundation interaction is of vital importance in engineering practice. Westergaard originally developed analytical expressions to compute the hydrodynamic pressure on a dam with vertical upstream face subjected to seismic ground motions. With advances in computer technology and the advent of finite element analysis, the numerical analysis of dams, with software such as DIANA, has become easier and faster.

This paper highlights the capabilities of DIANA to consider the effects of fluid compressibility and foundation flexibility. This is one of a collection of white papers written by staff members at TNO DIANA BV which are available for download on this website.
