The International Code Council's Evaluation Service Acceptance Criteria for Seismic Qualification by Shake-Table Testing of Nonstructural Components and Systems (ICC-ES AC 156) has become the main test standard that has been used in the performance of SSC for building applications.
Service (ICC-ES) issued a clarifying instruction entitled Acceptance Criteria for Seismic Qualification by Shake-Table Testing of Nonstructural Components and Systems (ICC-ES-AC156) in July, 2004. GE's shake-table testing procedures incorporate the requirements set forth in this instruction. Institute of Electrical and Electronics Engineers ...
Build a shake table—a device engineers use to simulate the back-and-forth shaking of an earthquake. Design a building that's stable and sturdy enough to survive an earthquake. Test your building on the shake table and see what happens! 2. Here are the materials to make the shake table. 2 pieces of sturdy cardboard (about 8½ x 11 in or A4)
Earthquake Simulator Laboratory. The signature piece of testing equipment at the PEER-UC Berkeley Lab is the six degree-of-freedom Shaking Table, the largest in …
Using the shake table at the University of Buffalo's Earthquake Engineering Research Center, the structure was subjected to simulated earthquakes that range in magnitude of 44% to of the 1994 6.7-magnitude Northridge, Calif., earthquake.
E-Defense is the world's largest shake table. In July 2009, Simpson Strong-Tie in collaboration with researchers from Colorado State University conducted a 7.5 magnitude test on a seven-story wood-framed condominium tower – the largest seismic test ever.
Shake Table Testing? • Post-test acceptance criteria for shake- table testing shall be as required by ICC-ES AC 156: 1. Structural Integrity of components, supports, and attachments shall be maintained. 2. Functionality of components shall be maintained equivalent to pre-shake table test functionality test.
These auxiliary structures must be fixed externally (out of the shaking table platform) because this type of equipment should not be subjected to a typical seismic level of vibration. Consequently, the absolute displacements measured must be deduced of the ones reproduced and controlled on the shaking table.
vibrations at the shake table earthquake test facilities of the ENEA Casaccia Research Center, Rome, Italy. The Object Tracking and 3-D optical movement detection and analysis have been experimented to track the motion during the low frequency (up to 30Hz) vibrations typical of the shake table earthquake …
