During earthquakes, ground failure is commonly caused by liquefaction. Thus, assessment of soil liquefaction potential in earthquake-prone regions a crucial step towards reducing earthquake hazard. Since Babol city Iran country located high seismic area, estimation great importance this city. For purpose, the present research, using field-based methods and geotechnical data (such as unit weight...

on april 15, 1979,a destructive earthquake struck the southwestern part of yugoslavia, in which the total damage exceeded 2.7 billion dollars. in this paper, major engineering lessons learned in this earthquake are discussed and illustrated with representative photographs. the main causes of failure of masonary and reinforced concrete buildings are pointed out. effect of architectural design on...

Beginning of the twentieth century, population growth, urbanization and industrialization has led to depletion of rapidly building areas. Accordingly, each passing day, the opening of the new construction sites has become mandatory. Among these newly opened areas, geotechnical aspects of construction from time to time in areas not suitable for construction and deployment was seen to improve the...

This paper presents prediction of liquefaction potential of soils by neuro-fuzzy models evaluated using Idriss and Boulanger method. In order to address the collective knowledge built up in conventional liquefaction method, an alternative Takagi-Sugeno-Kang reliant neuro-fuzzy model has been developed. Neuro-fuzzy is one of the artificial intelligence approaches that can be classified by machin...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

The fibre-reinforced soil-cement columns are used as remediation measure against earthquake induced soil-liquefaction associated large settlements in liquefiable loose surface layer of sand. This sand was overlying on the non-liquefiable dense bottom 1-g physical modelling shallow foundation carried out using shaking table. There were four models constructed for testing and two types improvemen...

Response of soil depends on both the mechanical properties of soil itself and the nature of loading. Many geotechnical engineering problems are associated with dynamic and cyclic loadings, such as ocean wave or ice loading applied on foundations of offshore structures or bridges, dynamic loading applied on foundations of offshore wind power structures, ocean wave loading on harbor structures, s...
