The need for transportation of fluids is increasing in recent years, calling for morecomplex analyses and design of the related facilities such as tanks, pumping stations, piperacks, etc. If these are located in a high seismicity area and over a weak soil profile, thedynamic soil-structure-interaction gets even more difficult to deal with, considering the highnumber of unknowns and time constraints in most projects. In this paper, detailed dynamicanalysis performed for the foundations of a pipe rack using finite difference software ispresented. The pipe rack rests on single or braced barrette foundations in a drain column-improvedsoil profile. In each analysis, the variation of acceleration along the soil profileand maximum moment and shear force values on the foundation elements are calculated.The most critical section, from the dynamic point of view, is found as the braced barrettefoundations resting on the region where drain columns are 37 – 41 m long. Anotherinteresting aspect of the analyses is the variation in the barrette forces when theirorientations were altered by 90°. Analysis results show that the moment and shear forces forthe “old” transverse direction can be used in the longitudinal direction in the revisedorientation of the four-barrette group.

A chemical substitution study for a wet processing textile mill in Turkey Öztürk, Ertan; Demirer, Göksel Niyazi; Department of Environmental Engineering (2007) The main environmental concern in the textile industry is about the amount of water discharged and the chemical load it carries. The total quantity of chemicals used in textile mills varies from 10% to over 100% of the weight of the cloth produced. Many chemicals currently used in the textile industry affect the amount and the type of waste produced and their influence the aquatic life of the receiving stream. One of the critical steps in pollution prevention studies is auditing the use of chemicals and mak...
A study of thin film solid phase microextraction methods for analysis of fluorinated benzoic acids in seawater Boyacı, Ezel; Viteri, C. Ricardo; Pawliszyn, Janusz (2016-03-04) Fluorinated benzoic acids (FBAs) are frequently used as tracers by the oil industry to characterize petroleum reservoirs. The demand for fast, reliable, robust, and sensitive approaches to separate and quantify FBAs in produced water, both in laboratory and field conditions, has not been yet fully satisfied. In this study, for the first time, thin film solid phase microextraction (TF-SPME) is proposed as a versatile sample preparation tool for the determination of FBAs in produced water by pursing two diffe...
A geochemical equilibrium modeling approach to assessing soil acidification impacts due to depositions of industrial air emissions Ünlü, Kahraman; Soyupak, S; Yurteri, C (1999-07-01) Soil acidification impacts arising from depositions of industrial air emissions may become a serious environmental concern. Currently, in the literature quantitative mechanistic modeling and the experimental acid neutralizing capacity (ANC) approach and a qualitative evaluation approach classifying soils into various levels of sensitivity to acid additions have been reported to assess the long-term soil acidification impacts due to industrial air emissions. Another alternative quantitative approach proposed...
An evaluation study on instrumentation system of Cindere dam Sezgin , Özgün İlke; Yanmaz, Ali Melih; Department of Civil Engineering (2008) In this study, the first hardfill dam in Turkey, Cindere Dam, is evaluated regarding current and alternative measurement systems in detail. Cindere Dam is a notable project, especially with its height as an example of hardfill dam, not only in Turkey but also in the world. First, the current instrumentation system of Cindere Dam is evaluated as a whole with reference to the parameters measured, instruments and data acquisition system. Second, an alternative instrumentation system is developed by using addit...
An assessment of the CO2 emissions reduction in high speed rail lines: Two case studies from Turkey Dalkıç Melek, Gülçin; Balaban, Osman; TUYDES-YAMAN, Hediye; CELIKKOL-KOCAK, Tumay (2017-11-01) Transportation sector is one of the major emitters of greenhouse gases due to high consumption of fossil fuels in passenger and freight transportation. In recent years, high speed rail systems (HSR) have become an important policy option for intercity transportation in many countries, including Turkey, as they have relatively low emissions impact. Currently, the total HSR network in Turkey extends to 1213 km and connects 7 cities mostly located along a main HSR corridor. Annual ridership of the first two li...
