Abstract (Summary)

The Modular Strong-Block Testing System is designed to be versatile, consisting of a number of possible configurations that would accommodate various types of experimental tests. The system is designed so that the stiffness of the system would be adequate to resist loads generated from experimental tests. The system is modular in nature, comprised of individual, reinforced concrete “strong-blocks.” Each strong-block is an identical 36 in. x 36 in. x 36 in. cube, with interlocking shear keys. The strong-blocks have eight internal anchorage points to secure test specimens and framing coupled with six longitudinal and four lateral steel post-tensioning ducts. The stiffness of the system is dependent on the ability of the strong-blocks to act monolithically, which is accomplished by post-tensioning. One-inch diameter DYWIDAG Threadbars are used to apply the post-tensioning force, each of which can be stressed up to 100,000 lbs., generating up to 600,000 lbs. of compression on the blocks. Vertically and laterally loaded experimental tests were conducted using the system. The uplift and joint behavior of the system were monitored during loading and test results show that the system maintains sufficient stiffness to justify its use for conducting experimental tests. Using the knowledge gained from the design, construction, and testing of the system, the Modular Strong-Block Testing System is a practical alternative to strong floor systems for conducting large scale experimental tests.
