Debris flow damage incurred to buildings: an in situ back analysis

摘要: In an attempt to conduct a back analysis of the damage caused 19th century masonry structure due October 2009 flash flood/debris flow event in Scaletta Zanclea, flood discharge hydrograph is reconstructed ungauged conditions. The for solid then estimated by scaling up liquid volume debris volume. diffusion simulated solving differential equations single-phase two-dimensional (2D) that employs triangular mesh elements, also taking into account channelling through buildings. building modelled using 2D finite shell elements and based on maximum hydraulic action flow. boundary conditions provided openings, floor slabs, orthogonal wall panels foundations are modelled. reconstruction case-study confirm location induced event.
