نویسندگان
چکیده
This paper reports the results of dynamic centrifuge tests carried out on sandy models alternatively equipped with vertical or horizontal drains. The main aim experimentation was to investigate use drains mitigate liquefaction susceptibility deposits and validate their applicability as a remediation technique applicable in urban industrial areas protect existing buildings from liquefaction. assessment validation were by comparing seismic behavior treated that untreated model

Liquefaction Hazard assessment using Horizontal-to-Vertical Spectral Ratio of Microtremor
In this paper, the spectral ratio of mmicrotremor, HSVR, is presented for estimating the liquefaction potential of layered soil in the coastal area of the Persian Gulf, which consists of a hard sandstone layer situated between two saturated sandy layers. The surface layer is thin, with a thickness between 2 and 5 meters. The purpose of this paper is to identify the relation between the liquefac...
متن کاملLaboratory Studies on the Effect of Vertical Gravel Column Drains on Liquefaction Potential
Abstract: In recent years deadly earthquakes in seismic areas have caused special concerns regarding liquefaction phenomenon by researchers and specialists. Excess pore water pressure in loose sediments may cause phenomena such as boiling, shearing strength and dynamic stiffness reduction and lateral movements cause difficulties. Many remedial methods such as soil replacement with proper materi...
متن کاملLiquefaction of Heterogeneous Soil: Centrifuge Study
A series of centrifuge liquefaction tests have been conducted at C-CORE’s geotechnical centrifuge facility: two on variable soil and one on uniform soil deposits. A single storied frame structure resting on two strip footings was also placed on that soil deposit. Experimental results such as accelerations, excess pore water pressures (EPWP) and settlements were monitored throughout the tests. R...
متن کاملNeuro-PD Controller of Structural System to Mitigate Earthquake Vibrations
In this paper, stabilization of the structural system against earthquake is presented. Because the conventional PD controller is popular and simple in design, our controller is based on PD controller. The main problem of such a controller is its inability to produce desired response and instability against variations in the properties of the structural system. To obviate this issue, the neu...
متن کاملNumerical modelling of multi-directional earthquake loading and its effect on sand liquefaction
Earthquakes generate multi-directional ground motions, two components in the horizontal direction and one in the vertical. Nevertheless, the effect of vertical motion on site response analysis has not been the object of extensive research. The 2010/2011 Canterbury sequence of seismic events in New Zealand is a prime example among other earlier field observations strongly corroborating that the ...
