In this research, nonlinear dynamic analysis of concrete shear wall using a new nonlinear model based on damage mechanics approach and considering bond slip effects is presented. Nonlinear behavior of concrete is modeled by a rotational smeared crack model using damage mechanics approach. The proposed model considers major characteristics of the concrete subjected to two and three dimensional l...
The relationship between chloride ion concentration and pH on de-passivation of steel rebar embedded in concrete was investigated by a two frequencies impedance measurement using probe electrodes. A saturated calcium hydroxide solution used for the electrolyte as simulated pore solution. pair electrodes, which simulates rebar, immersed prepared an arbitrary ions, performed. Air supplied to simu...
the purpose of this study is to investigate the influence of cross-cultural communication (ccc) on stakeholder management process (smp) in international construction projects from the turkish stakeholders’ perspective. the research is based on a survey of turkish stakeholders (contractors, consulting engineers, insurance brokers, and financial advisors) operating internationally. the useable su...

Degradation of the cementitious bond between steel rebar and concrete and that between old and new mortar under cyclic shear loading was observed nondestructively by measuring the contact electrical resistance of the joint. Degradation, which caused a decrease in bond strength but no visual damage, was indicated by an abrupt increase in the resistance at a small fraction of the fatigue life. Bo...
Ground-penetrating radar (GPR) detects a tunnel with relatively low-frequency electromagnetic waves, which can result in poorly characterized reinforced steel bar (rebar) hyperbolas and make it challenging to recognize rebar. Thus, the rebar is located by using attenuation reflection coefficients, hyperbolic feature of reconstructed for recognition. Due differences properties other media second...
A 42-year-old woman was referred to our institution with sudden onset of ataxia, facial paresis, horizontal gaze palsy, and progressive dysarthria. The patient worsened within a few minutes, with appearance of left hemiparesis. The National Institutes of Health Stroke Scale Score was 13. On computer tomography scan 2 hours after stroke onset, no brain stem lesion or intracranial bleeding was vi...
