The Yu- experiment

To validate structural performance of reinforced concrete structures many tests on RC assemblages have been carried out under column removal scenarios. They provide valuable information on structural dynamic performance. One such experiments was executed at the Fraunhofer Institute for High-Speed Dynamics by following the specimen design by Jun Yu and Kang Hai Tan: A ca 6 meter long concrete beam supported by a center concrete pillar was loaded with a constant 47kN in form of two huge concrete block weights . The center pillar was then suddenly removed by explosives.
