In common buildings the soil-structure-interaction (SSI) is governed by the elastic behavior of the building. The best conditions to see the soil effect predominate would be a dynamic rigid body movement of a massive building. For this reason measurements were carried out on an old anti-aircraft tower from World War II on typical Viennese soil conditions. The dynamic properties of the soil coul...

Artificial monolayer black phosphorus, so-called phosphorene, has attracted global interest with its distinguished anisotropic, optoelectronic, and electronic properties. Here, we unraveled the shear-induced direct-to-indirect gap transition and anisotropy diminution in phosphorene based on first-principles calculations. Lattice dynamic analysis demonstrates that phosphorene can sustain up to 1...

In powder handling operations, such as mixing, conveying, sieving and milling, particles frequently make contact with each other and the walls of the processing equipment. During these interactions, the electrification of particles takes place, commonly known as tribocharging. This paper focuses on investigating the tribocharging characteristics of bulk powders under shear deformation. In parti...

an earthquake with the magnitude of 5.9 mw occurred in qeshm island and hormozgan province in november 27th 2005. 3d co-seismic deformation field caused by the earthquake are determined based on the ascending and descending interferograms and azimuth offsets. the peak to peak estimated displacement is about 10 cm in west, 69 cm in north and 22 cm in vertical directions. we apply strain analysis...

There are a number of parameters influencing the dynamic and seismic response of bridges. Of these, two important parameters warranting special notice include: the properties of the neoperenes in the state of connection between girders and columns and the shear stiffness of underlying soil in the level of bridge substructure’s connectivity to the ground. In &#10this paper, the effects of these ...

In recent years, many large-scale projects have been built on thick soft soil foundations. Due to insufficient understanding of the engineering properties soil, major accidents occurred. Based intersection project Nangangdao Bridge and subway tunnel in Fuzhou, order study disturbance degree pile foundation construction surrounding under influence multi factor coupling, direct shear test differe...

Abstract Soil, rocks and rock masses dilate or compact when sheared, i.e., distortion necessitates volume change. This coupling between distortional strains volumetric strains, described by stress–dilatancy theories, endows soils with manifestation of peculiar characteristics they are subjected to shear. Stress–dilatancy theories have become central in describing the mechanical energy dissipati...

Oil-pollution due to accidental during transportation or leakage from storage not only brings large damage to the environments, but it also affects the geotechnical properties of soil. Hence, an extensive laboratory testing program was carried out to investigate the geotechnical properties on palm biodiesel contaminated weathered granite soil and mining sand. A series of laboratory experiments ...

This paper assesses the dynamic nonlinear free-field soil response under bidirectional horizontal non-uniform excitation through a series of multi-point 1 g shaking table tests. The bed was enclosed in an innovative box supported by array three shake tables and subjected to uniform ground motions one two directions. unidirectional excitations, both non-uniform, were compared discussed terms acc...
