Deformation of the silo wall due to the single ball impact is modeled in ANSYS. The material in silo, as a Winkler bed, is replaced by spring-damper elements and the spring stiffness and damper coefficients are evaluated of the granular material and wall properties. The granular material deformation under the specified force is measured to evaluate the granular stiffness to be used for determin...


 In the process of metro station construction, partition wall is usually used to prevent displacement soil behind ensure construction platform. This research aims analyze response keep safety structure. The time-horizontal and cracks are measured during construction. finite element software FLAC 3D simulate wall, reasons cracking analyzed by simulation measurement data. stiffness self-sta...

Generally seepage analysis and stress–strain analysis are conducted separately in the analysis of dams with varied water levels, which neglects the impact of soil deformation on seepage. The impact, however, is significant when the water level varies greatly. In this study, a simplified approach for consolidation analysis of unsaturated soil is used to conduct numerical simulations of water-fil...

The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (RC) slabs that provide an efficient rigid diaphragm action, no longer satisfy the seismic design check and have been retrofitted by adding or ...

Experimental and numerical investigations on the retrofitting of half-scale wall-like reinforced concrete (RC) columns were conducted. The axial compressive behavior control un-strengthened RC column (having a section aspect ratio four) was compared with strengthened columns. by employing external confinement through fiber-reinforced polymer (FRP) wraps and/or steel/FRP strips with/without modi...

Male rats with a chronically implanted device that allowed photoelectric plethysmographic measures to be made of the stomach wall were trained while paralyzed with d-tubocurarine and being artificially respirated. One group was reinforced by avoidance of and/or escape from electric shocks to the tail, whenever increases in the transmission of light through the stomach wall occurred during a CS;...
