International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
Soil conditions and site effects play an important role in the vulnerability assessment of lifelines and infrastructures under strong seismic excitation. Due to the spatial extent of these networks, they are subjected to non-uniform and incoherent ground motion as a result of the variability of soil and geological conditions; consequently their vulnerability assessment depends entirely on the variability of soil conditions and ground motion, known as site effects, for a given seismic scenario. Fragility functions for the exposed elements at risk, composing the different lifelines and infrastructure systems, play an equally important role. The paper presents some selected results of …

Accuracy Of Empirical Equations Predicting Sliding-Block Displacement,

Accuracy Of Empirical Equations Predicting Sliding-Block Displacement, Tryfon Thomaidis, Constantine A. Stamatopoulos
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The sliding-block model forms the basis of simple models predicting permanent co-seismic shear displacements of soils. For excitations consisting of actual accelerograms, different parameters of the applied motion have been used and different expressions have been proposed by researchers. Recently, many accelerograms have been recorded and these accelerograms are available in internet sites. These accelerograms allow the investigation of the accuracy of the expressions described above, some of which were based in a small number of accelerograms. In the present work the accuracy of empirical equations predicting sliding-block displacement is studied thru the application of 101 accelerograms covering a wide …

Assessing Horizontal Seismic Coefficients In Earth Dams With Regards To Expected Deformation, Mohammad Hossein Tavakol, Ali Komak Panah
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
One of the most important aspects that must be considered in design of embankment dams is to assess their stability during seismic events. When employing sophisticated approaches like finite element method for dynamic analysis of the mentioned structures against earthquake attacks, difficulties in evaluation of input parameters may exist. Hence employing simpler approaches like pseudo static method are still preferred by some designers. However, there is a problem associated with the pseudo static procedure as there is no organized technique for precise evaluation of horizontal seismic coefficient. Moreover, this method applies "safety factor" for the stability evaluations which is not …

Verification Of Potential Flaws In Computing Liquefaction Po-Tential Index By 1999 Chi-Chi Earthquake In Taiwan, Chihping Kuo, Muhsiung Chang
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
A widely used method for evaluating the damage and possibility of soil liquefaction, called Liquefaction Potential Index (PL), was proposed by Iwasaki in 1982. The values of 5 and 15 are the critical boundaries of PL to describe the damage which soil liquefaction will occur. The method is also adopted in the building design codes in Taiwan. The index is computed in form of integration by mul-tiplying the danger function (i.e. 1 minus safety factor) and the depth weight function. Theoretically, the computation should adequately reflect the liquefaction potential for the depth interval calculated. If the danger …

Undrained Response And Liquefaction Behaviour Of Non-Plastic Silty Sands Under Cyclic Loading, K. Ranga Swamy, A. Boominathan, K. Rajagopal
International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
The undrained response and liquefaction behaviour of fine sand and silty sands consisting of 30% and 50% non-plastic fines were investigated in the present study. The effect of consolidation stress level, cyclic stress amplitude and amount of non-plastic fines on soil liquefaction have been studied through a systematically planned stress controlled cyclic triaxial tests. To examine the effect of consolidation pressure on liquefaction behaviour, the sand-silt specimens were prepared at 40% relative density and consolidated at pressures of 50, 100 and 200 kPa. To investigate the effect of fines content on liquefaction resistance of sands at constant postconsolidation void ratio, …

Success Dam is located on the Tule River, near the city of Porterville, California. The dam is a rolled earth-fill embankment approximately 145 feet high and 3,400 feet long. The embankment is comprised of a central impervious core protected by upstream and downstream outer pervious zones. A majority of the dam is founded on potentially liquefiable Holocene alluvium. Several analytical techniques of varying complexity have been used to determine the liquefaction potential of the foundation Holocene alluvium and the pervious embankment shells. The following analytical techniques were used on the Success Dam Remediation Project: (1) cyclic stress ratio (CSR) evaluation …
