Soil-foundation interaction model for the assessment of tunnelling-induced damage to masonry buildings

چکیده
• A simplified model is developed for tunnel-soil-building interaction problems. The soil response represented by a nonlinear Winkler model. soil-foundation provides good match with 3D finite element analysis. Frictional sliding at the interface significant mechanism. Shallow tunnel construction inevitably causes local ground movements to occur. In an urban environment, these may cause damage existing buildings on surface. This paper describes new, simplified, one-dimensional (1D) use in assessment analyses of that are risk tunnelling-induced damage. Simplified models this sort facilitate efficient building assessments infrastructure projects. proposed intended principally traditional load-bearing masonry founded embedded shallow foundations. (incorporating shear and normal tractions acting foundation possibility frictional gapping beneath footing) used represent interaction; also means specifying tunnel-induced movements. demonstrated combining it 2D plane stress facade; combined shown provide close representation facade movements, as computed corresponding model, but small fraction computational cost.

The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...

The base level is among the effective parameters in determining the seismic force on a structure, if the equivalent-static method is used for analyzing a structure. It is obvious that the base level is located on foundation in buildings in which foundation is built in a single level and there is not any interaction between the structure's walls and the soil; however, in some buildings which hav...
