Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …

Design of Deep Beam Using Strut-and-Tie Method A Case Study of Pile Cap
Abstract: This study takes a look at modeling of deep beam using strut-and-tie method using pile cap as a case study. There are B and D region in the deep beam (B standing for beam or Bernoulli and D standing for discontinuity or disturbance). A deep beam has a span-depth, a/d ratio ranging from 2.0 to 2.5. Thereafter, the strut-and-tie modeling (STM) of pile cap was displayed. The STM was later …

Strain Life Approach for the Fatigue Evolution Model of Concrete under Constant Amplitude Bending Fatigue Loading
Abstract: Strain life approach for the fatigue evolution model of concrete under constant amplitude bending fatigue loading plays a very important role in the material properties such as the fatigue strain, fatigue modulus and fatigue damage, presented in this paper by the nonlinear fatigue evolution model, and the hypothesis of recycle-ratio-related fatigue strain amplitude that causes stiffness degradation and inelastic deformation. The fatigue evolution model of concrete under constant amplitude bending …
