EDEN PRAIRIE, Minn., Aug. 26, 2013 /PRNewswire/ -- MTS Systems Corporation (NASDAQ: MTSC), a leading global supplier of high-performance test systems and position sensors, today announced the 30-year anniversary of a collaboration with Tongji University in Shanghai to support disaster-reduction research in civil engineering. Tongji University has conducted more than 900 seismic tests using MTS equipment to help reduce the effects of devastating earthquakes on structures such as bridges and buildings.
The anniversary celebration coincides with the successful completion of their Multi-Functional Shaking Tables Lab, which features test equipment designed and built by MTS. The lab recently tested a scaled-down version of Jiangsu's Taizhou Bridge, a mega-structure that spans 62 kilometers (38 miles) and opened to the public in 2012.
"Our system was able to provide the Tongji Lab with a much deeper understanding of how well a multi-tower, multi-span suspension bridge would hold up during an earthquake," said Dr. Rich Baker, Senior Vice President and General Manager of MTS Test. "It also helps advance China's natural disaster reduction initiatives by providing data that helps researchers enhance the seismic resistance of structures."MTS, a world leader in earthquake simulation testing capabilities, designs and builds the shaking table systems. These systems come in different sizes and configurations and enable labs to test small-scale structures to full-size buildings. Shaking tables use hydraulic actuators that replicate movements experienced by a structure during an earthquake or seismic event. In addition to the Taizhou Bridge, the Tongji Lab has conducted seismic testing for structures such as the Shanghai World Financial Center, Shanghai Shimao International Plaza, Guangzhou Nature Center and the LG Beijing Towers. "Tongji University has a decades-long relationship with MTS, collaborating on earthquake simulation shaking table test systems that are among the most effective in the world," said Dr. Zheng Lu, a professor of seismic research at Tongji University. "Together we have successfully conducted seismic tests on significant municipal projects, transportation systems and high-rise buildings around the world." MTS supplied a two-dimensional system to Tongji University's Shaking Table Testing Division in 1983. It was later upgraded to a three-dimensional system with six-degrees-of-freedom – a design capable of conducting even more complex seismic tests. For the Taizhou Bridge test, MTS supplied a first of its kind system with a series of shaking tables supporting up to 200 tons that can be arranged in many configurations.
