A photoelastic investigation of anchorage bearing stresses Available to Purchase

This investigation focuses on a number of features which have hitherto been less researched but which have been found to be critical in the behaviour and failure mechanism of anchorage zones. These include the mode of load transfer, the proximity of the anchorage unit to the surface plane and the critical role of the high sub-surface shear in the immediate vicinity of the anchorage unit. The results show the significant advantages of the embedded anchorage over the corresponding external unit and the critical dependence of the surface stresses upon the proximity of the anchorage unit. In a typical multi-anchorage end-block. the behaviour of adjacent units is found to be sensibly independent.
