Modeling of the beam discontinuity with two analyses in strong and weak forms using a torsional spring model
In this paper, a discontinuity in beams whose intensity is adjusted by the spring stiffness factor is modeled using a torsional spring. Adapting two analyses in strong and weak forms for discontinuous beams, the improved governing differential equations and the modified stiffness matrix are derived respectively. In the strong form, two different solution methods have been presented to make an a...

متن کاملModeling Roughness of Rock Discontinuity Surfaces: A Signal Analysis Approach
Barton’s (1973) model for estimating the peak shear strength of rock discontinuity surfaces includes an input variable, called joint roughness coefficient (JRC). Using this model, Barton and Choubey (1977) empirically determined the JRC values of a large number of discontinuities and designated a set of ten roughness profiles (Fig. 1) that represents the JRC range of 0–20. These ten profiles co...
متن کاملNumerical Simulation on Zonal Disintegration in Deep Surrounding Rock Mass
Zonal disintegration have been discovered in many underground tunnels with the increasing of embedded depth. The formation mechanism of such phenomenon is difficult to explain under the framework of traditional rock mechanics, and the fractured shape and forming conditions are unclear. The numerical simulation was carried out to research the generating condition and forming process of zonal dis...
متن کاملNumerical Modeling of Rock Slopes with a Potential of Block-Flexural Toppling Failure
One of the most important instabilities of rock slopes is toppling failure. Among the types of toppling failure, block-flexural failures are more common instability which occurs in nature. In this failure, some rock blocks break because of tensile stresses, and some overturn under their weights, and next to all of them topple together. Physical and theoretical modeling of this failure is studie...
