Theoretical and experimental studies on loadbearing masonry walls have shown the significant influence of axial load level (i.e., precompression) wall aspect ratio in-plane lateral resistance. Nonetheless, impact precompression spatial variability material properties needs to be further investigated at scale with openings. This study presents a stochastic analysis unreinforced (URM) pier–spandr...

The slope reinforcement scheme has an important influence on the prevention and control of landslides. A reasonable can improve reliability, economy efficiency landslide resistance. It is urgent to establish a local precise method for landslides basis clear process instability modes Taking high-steep anti-dip rock as example, six numerical models are established by using continuum–discontinuum ...

Abstract It is often argued that the indispensability of continuum models comes from their empirical adequacy despite decoupling microscopic details modelled physical system. There thus a commonly held misconception temperature varying across region space or time can always be accurately represented as continuous function. We discuss three inter-related cases modelling — in phase transitions, t...

In this paper, using the continuum-discontinuum element method (CDEM), fragmentation and outburst process of coal specimen are simulated, main factors affecting breaking explored. The results show that after seam is uncovered, generates obvious failure trend. Near coal-free surface, fracture blocks generate significant displacement, resulting in larger opening widths cracks. Coal deep cracks wi...

Abstract. It is shown that for an L1-predual space X and a countable linearly independent subset of ext(BX∗) whose norm-closed linear span Y in X∗ is w∗-closed, there exists a w∗-continuous contractive projection from X∗ onto Y . This result combined with those of Pelczynski and Bourgain yields a simple proof of the Lazar-Lindenstrauss theorem that every separable L1-predual with non-separable ...

A Hydro-Geomechanical View of Seal Formation and Failure in Overpressured Basins — The formation of seals, and the consequent retention of overpressure, is a common and expected event during normal basin evolution in active basins that have a significant mudrock succession. Seal failure, and the resultant limitation to fluid-pressure increase (valve action), is also an expected process. Hydroge...
