Most of the widely used seismic soil liquefaction triggering methods propose cyclic resistance ratio (CRR) values valid at the reference normal effective stress (sigma(v,0)') of one atmosphere and zero static shear stress (tau(st,0)) states. Then, a series of correction factors are applied on this reference CRR, for the purpose of assessing the variability due to normal effective and static shear stress states (i.e. K-sigma and K-alpha corrections) acting on the horizontal plane. In the literature, a number of relationships suggested to be used as part of liquefaction triggering methodologies. However, the presence of a wide range of correction factors, some of which with even contradicting trends, suggests that more research needs to be performed to reduce this uncertainty. Additionally, these stress correction factors are treated as being strain-independent and are applied disjointedly to CSR or CRR. The main motivation of this on-going study is defined as to develop a strain-dependent semi-empirical framework to assess combined effects of i) sigma(v,0)', ii) tau(st,0) acting on the plane, where cyclic shear stresses either produce iii) shear stress reversal or not. For this purpose, cyclic simple shear tests were performed on laboratory reconstituted sand samples. Additionally, cyclic test data were compiled from the available literature. On the basis of probabilistic assessment of this data, a unified correction scheme, which incorporates the interdependent effects of both overburden and static shear stresses along with the degree of cyclic shear stress reversal, has been developed.

Unified assessment of stress scaling factors for liquefaction engineering problems
Çetin, Kemal Önder (2014-01-01)
Most of the widely used seismic soil liquefaction triggering methods propose cyclic resistance ratio (CRR) values valid at a reference normal effective stress (σv,0) of one atmosphere, and a zero static shear stress (τst,0) state. Then a series of correction factors are applied to the CRR to account for the effects due to variations from the reference normal effective and static shear stresses (i.e., Kσ and Kα corrections). In the literature exists a number of stress correction factors used for seismic soil...
Seismic Behaviour of RC Frames Infilled with Different Techniques
Demirel, İsmail Ozan; Yakut, Ahmet; Binici, Barış (2017-01-09)
Besides their primary implementation as heat isolation and partitioning off the living space, infill walls have great potential to influence building response during seismic excitation. Affecting the infilled RC building stock of Turkey, Mw 7.4 Kocaeli (1999) and Mw=7.1 Van (2011) earthquakes have shown that “non-structural” infill walls might be very critical for vertical stability of buildings under severe earthquakes and their performance is important in determination of global building performance espec...
DEFORMATION ANALYSIS OF TWO LAYER COMPOSITE TUBES UNDER CYCLIC LOADING OF EXTERNAL PRESSURE
Eraslan, Ahmet Nedim (2016-01-01)
The stress response of axially constrained two-layer composite tubes under cyclic loading of external pressure is investigated in this study. Elastic and elastoplastic stress states for the tube assemblies are examined by developing a mathematical model based on Tresca's yield criterion, its associated ow rule, and linear strain hardening. Using this model, the composite tubes with different dimensions are analyzed under one cycle of loading, unloading, and reloading of external pressure. It is observed tha...
Thermal fracture analysis of orthotropic functionally graded materials using an equivalent domain integral approach
Dağ, Serkan (2006-12-01)
A new computational method based on the equivalent domain integral (EDI) is developed for mode I fracture analysis of orthotropic functionally graded materials (FGMs) subjected to thermal stresses. By using the constitutive relations of plane orthotropic thermoelasticity, generalized definition of the J-integral is converted to an equivalent domain integral to calculate the thermal stress intensity factor. In the formulation of the EDI approach, all the required thermomechanical properties are assumed to ha...
Thermal stability of benzorods: Molecular-dynamics simulations
Malcıoğlu, Osman Barış (Elsevier BV, 2005-12-01)
Thermal stability of benzorods 2C6-20C6, which are obtained by stacking n (n=2-20) dehydrogenated benzene, have been investigated by molecular-dynamics simulations. It has been found that these structures assume a geometrical form depending on the number of dehydrogenated benzene layers, and they are stable under heat treatment up to elevated temperatures with a dependence on length.
