The application of critical state framework depends on the presence of either a unique critical state line (CSL). However, many authors have observed that a transitional behaviour occurs in certain granular intermediate soils in which the fines content and the initial void ratio have a significant effect on the location of this line. This work investigates these effects in poorly graded granular soils as previous studies reported that this type of soil does not exhibit transitional behaviour. Results from this study reveal that poorly graded fine-grained sand exhibits transitional behaviour similar to that of intermediate soils, and subsequently, it can be grouped into ranges of initial densities in which each group approaches a unique CSL in v:lnp' space. A unique state boundary surface is identified by determining the critical state parameters from each group and using these parameters to normalise the stress paths; this shows that the critical state framework can be successfully applied to this type of soil.

Influence of idealized pushover curves on seismic response Kadaş, Koray; Yakut, Ahmet; Department of Civil Engineering (2006) Contemporary approach performance based engineering generally relies on the approximate procedures that are based on the use of capacity curve derived from pushover analysis. The most important parameter in the displacement-based approach is the inelastic displacement demand computed under a given seismic effect and the most common procedures employed for this estimation; the Capacity Spectrum Method and the Displacement Coefficient Method are based on bi-linearization of the capacity curve. Although there ...
Influence of the nonlinear behavior of semi-rigid connections on the analysis of low-rise steel framed structures Karakaş, Zafer; Sarıtaş, Afşin; Department of Civil Engineering (2017) In this thesis, the influence of several parameters to hysteretic behavior of semi-rigid connections on general response of low-rise special moment resisting frames (SMRF) is investigated. Two different types of low-rise structures, which are presented in SAC steel project, are taken into account. 1997 NEHRP (FEMA 1997a) and 1997 AISC provisions compliant flexible (lower bound) and rigid (upper bound) frames are selected to examine the influence of nonlinear behavior of connections on structural system resp...
Influence of peak ground velocity on seismic failure probability Sucuoğlu, Haluk; Erberik, Murat Altuğ; Yücemen, Mehmet Semih (1999-06-10) This study focuses on the damage potential of earthquake ground motions based on the inelastic dynamic response of equivalent single degree of freedom structures. Their yield resistances are selected in accordance with seismic design codes. An index accounting for the accumulation of damage due to inelastic excursions is used to represent structural damage. A set of 94 ground motions are employed for this analysis, which are all scaled to the same peak ground acceleration of 0.4 g. Earthquake ground motions...
Quantitative approach to rapid seismic evaluation of slab-on-girder steel highway bridges Dicleli, Murat (1996-01-01) A quantitative approach follows for developing a methodology for the rapid seismic evaluation and ranking of slab-on-girder steel highway bridges. In the development of this methodology, analytical expressions are introduced to calculate the seismically induced forces and displacements in bridge components, first assuming that damage to bearings is not acceptable and then removing this constraint. In the latter case, the superstructure is assumed to become unrestrained and slide on its supports. The seismic...
Properties of charmoniumlike states Özşahin, Hikmet; Alıyev, Tahmasıb; Department of Physics (2015) In this work, hadronic properties of exotic meson candidate Y (3940) and its orthogonal state are studied. These meson states are considered as a mixture of charmonium ( c0) and meson molecule. The interpolating quark currents for c0 and D D are used to construct the correlation function. QCD sum rules approach for two-point function is then used to derive OPE and phenomenological representation of the correlation function of these mesons. Next, these two representations are connected by the analytical co...
