The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...
The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...
the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...
The spatial organisation of soils is crucially important in affecting belowground function, and the associated delivery of ecosystem services. Fungi constitute an important part of the soil biomass. As well as playing key roles in nutrient cycling and biotic interactions, they are also intimately involved in soil structural dynamics. Fungi mediate the formation of soil structure at a variety of...
In order to properly assess the feasibility of using Laser-Induced Fluorescence (LIF) spectroscopy for soil monitoring, the variation of fluorescence intensity due to the heterogeneity and complexity of soil media was investigated. Different soil minerals showed fluorescence spectral structures distinguishable from the contaminants, implying dissimilar interactions or the binding of contaminant...
fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. it may affect symbiotic relationship between range plants and mycorrhiza. accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. the study was conducted in a semi-arid steppe rangeland ...
The effects on hydromechanical performance due to chemical interactions between pore solution and soil components in lime-treated are investigated. Static- kneading-compacted soils percolated by demineralized water (DW) a low-ionic strength solution. Kneading action causes aggregate deformation, thus consequently reducing macropores of diameter 105 Å. This increases the hydraulic tortuosity len...
This review examines the effect of tillage on microbial habitat space, and the roles of microbes in in ̄uencing Ntransformation processes within a heterogeneous soil environment. Literature relating tillage to microbial processes is assessed critically focusing on (a) degrees of physical disruption and N-processes, (b) interactions between organisms and the soil pore network, and (c) the role of...
