... Abstract Yield-Line Theory (YLT) has been in wide spread use since the 1960's.YLT allows determining of the upper-bound bending resistance of reinforced concrete slabs using the concept of virtual work.YLT can be used for two purposes in the design of sprayed concrete support...

... through the side shear resistance and the end bearing resistance (Horvath et al. 1983). Although There are significant advantages in designing to include a base [or end bearing] resistance component (Williams and Pells 1981), the end bearing resistance is often ignored in current design practice (Crapps...

... in rock, the experimental data of electrical resistance were measured with stress or strain changing. The electrical resistance of siliceous-lime marble increases continuously with compressive stress from the initial loading to the greatest stress, but the increasing rate of electrical resistance...
