...) concrete blocks on an artificial soil slope with two block sizes and three slopes, and (2) concrete blocks bonded to the concrete base with different contact area. The LDV measurements agreed with conventional seismometer measurements. The dominant frequency of the blocks varied with the stability...

... ABSTRACT The shearing behaviour of both steel rebar and hollow strand cable bolt across joints and shear planes in concrete blocks is examined experimentally. The steel rebars (bolts) were tested in 20, 40, 50 and 100MPa concrete blocks, subjected to different pretension loads of 0, 5, 10, 20...

... Summary The object of this report is to clarify quantitatively the strength characteristics of a bedded rock by shearing tests both in-situ and in laboratory. Namely, shearing tests in-situ were carried out on a concrete block placed on a slate while tests in laboratory were carried out...
