Abstract Convergent plate boundaries show sharp variations in orogenic width and extent of intraplate deformation. Analysis late Cenozoic contractile deformation along the Andean mountain front adjacent foreland highlights contrasting degrees advance toward interior. The retroarc positions topographic (marked by frontal thrust-belt structures) (defined isolated basement block uplifts) range fro...

The subduction of positively buoyant features has been implicated in the development flat and shallow dipping slabs, formation cusps trench geometry, cessation associated arc magmatism. However, how such anomalies influence dynamics to produce these different tectonic expressions remains debated. In this paper, using a series multi-material 3-D simulations free subduction, we investigate linear...

Accretionary wedge earthquakes usually occur in the overriding crust close to trench or above cold nose of mantle wedge. However, mechanism and temperature properties related slab dip angle remain poorly understood. Based on 3D thermal models estimate subduction plate structure, we investigate distribution Alaska, which has a varying along trench. The horizontal distance wedge-earthquake hypoce...

For the problem of stiffness calculation a composite slim beam with reinforced concrete truss slab as floor slab, short-term deflection is calculated and analyzed by theoretical numerical methods. The result shows that load-deflection curve linear in middle span beam, cross section ideal section. flat can be according to elastic theory. area converted into steel method conversion section, then ...
