THE SEISMIC BEHAVIOR OF BURIED SEABED WALLS IN LIQUEFACTION SOIL

نویسندگان

چکیده


 The present study aimed to investigate the seismic behavior of enclosed seawater walls, buried site which lies in liquefaction soil. An experimental specimen was manufactured and tested on table, a numerical also modeled ABAQUS software based outcomes. In both studies, susceptible layer around root wall considered due lean soil leakage large lateral pressure, behind caused failure section. According results, movement significantly decreased backing effect this section wall. Furthermore, an active wedge formed from side back containment, braces were overwhelming presence locks their along with wedge. displacement crown foot increased base acceleration higher frequency entrance movement.

Non-linear Transient Behavior during Soil Liquefaction Based on Re-evaluation of Seismic Records

Focusing on soil liquefaction, the seismic records during the Niigata-ken earthquake in 1964, the southern Hyogo prefecture earthquake in 1995 and the 2011 off the Pacific coast of Tohoku earthquake are analyzed by the non-stationary Fourier spectra. The shift of dominant frequency in the seismic record of Kawagishi-cho during the Niigata-ken earthquake is evaluated based on the time-variant pr...

Investigation of Liquefaction Mechanism and Displacement in Buried Sand Layers

One of the most important reasons for damages during earthquakes is the liquefaction of loose and saturated sand soils. However, in many regions with proper soil specifications, the large settlements have been observed in the ground surface. Loose sand layers buried in fine soils are one of the cases which may result in these problems and as a weak point during earthquake can cause this phenome...

Seismic Behavior of Intermediate Beams in Steel Plate Shear Walls

This paper presents some preliminary results of an ongoing research whose objective is to investigate the seismic behavior of intermediate beams (i.e., the beams other than those at the roof and foundation levels) in multi-story steel plate shear walls (SPSWs). Of primary interest is the determination of the strength level needed to avoid the formation of in-span plastic hinges, a relevant prac...

Finite element assessment of the effects of seismic loading rate on soil liquefaction

The influence of frequency content of seismic excitation on the extent and pattern of pore-water pressure build-up in saturated soil deposits is addressed. Seismic acceleration time histories are generated as uniformly modulated nonstationary stochastic processes, in accordance with prescribed response spectra and prescribed modulating functions. Based on numerical examples, it is shown that th...
