This book was released on 2018 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Piles are structural members that transfer the applied load of superstructures to deep supportive layers of soil or bedrock. Besides controlling the settlement of structures, piles provide sufficient capacity that other foundations cannot provide or provide only at a high cost. Despite ample research on the shaft resistance of displacement piles in cohesionless soils, the mechanism of such resistance remains unclear. Consequently, theories on shaft resistance have generated several discrepancies in predicting the capacity of displacement piles in cohesionless soils, not only due to the complexity of modeling cohesionless materials and collecting field data but also because the role of overconsolidation in such soils, which is often neglected. Although the critical depth of pile foundation in cohesionless soils has long been debated, definite conclusions have yet to be drawn. Overconsolidation in cohesionless soils directly affects the lateral earth pressure that acts upon the pile shafts and thus upon pile capacity. Overconsolidation can occur naturally or artificially when the ground surface is subjected to erosion, excavation, or unloading, often due to glacial melting, the demolition of structures, raised water tables, compaction, or vibration. This thesis presents an experimental investigation into the capacity of driven piles in overconsolidated cohesionless soils. Tests, with an emphasis on the shaft resistance and the critical depth, were conducted on long piles in a setup that permits measuring the overconsolidation ratio in the test tank as well as the total and local shaft resistance on the pile's shaft. Shear stress distribution along the pile's shaft showed some dependency on embedment depth ratio (L / D). Also, critical depth was observed for shaft resistance only when mean shaft resistance was analyzed, and was in line with Meyerhof's (1976) results. An analytical model was also developed based on limit equilibrium analysis using the horizontal slice method to predict the shaft resistance of a pile driven into normally consolidated cohesionless soils. The model assumes an inclined failure surface around the pile that accounts for the shear and normal stresses upon it. Critical depth was not only observed but also increased linearly as the angle of shearing resistance increased. A three-dimensional numerical model was developed and validated experimentally to perform 200 pile load tests in soils with various densities and at a range of embedment depths. Design theories to predict the shaft resistance of displacement piles in cohesionless soils and the critical depth were developed, design charts are presented.

Book Synopsis A Medium Scale Experimental Study of Pile Setup by : Rami Ksaibati
Download or read book A Medium Scale Experimental Study of Pile Setup written by Rami Ksaibati and published by . This book was released on 2016 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Piles driven into cohesive soils will usually exhibit an increase in resistance over time known as pile setup, freeze, or gain. Benefits of using this Phenomenon to the advantage of a foundation design can be found directly in the economic gains of requiring less foundation piles and time. Current research practices on pile setup is often performed on full scale instrumented piles around 60 – 100 feet in length driven at a construction site. Limitations of this research method include cost, time, heterogeneity of subsurface soil, inaccuracies of subsurface characterization, impractical extraction and reuse of sensors and pile. These limitations are addressed by the developed medium scale laboratory experiment described in this research. The developed experiment featured a five foot diameter, seven foot tall reinforced concrete manhole filled with compacted soils and vibrating wire piezometers and earth pressure cells placed along the depth. A 4 inch diameter, 7 foot long steel pile was driven into the soil profile to a 5 foot depth followed by dynamic and static load tests performed over a period of 1–3 weeks. Miniature cone penetration tests (CPT) were performed before and after pile driving to assess its impacts on surrounding soil. Four separate tests were performed on different soil profiles of sand and/or clay combinations. Measured pile resistances showed logarithmic increases with time in clay layers along the pile shaft. Total shaft resistances increased from 3.3 to 6.3 times the end of driving resistance in profiles containing clay. The excess pore water pressure dissipation caused from pile driving and measured horizontal effective stress were found to correlate well with measured shaft resistances; an inverse correlation was also found between rate of pile setup and time to 99% excess pore water pressure dissipation. CPT results showed similar tip resistances measured before and after driving at a 5 pile diameter distance from the pile indicative of an influence zone not extending beyond this distance. Results produced in this medium scale testing program agree with those obtained from full scale pile testing making this a better alternative for research purposes. Specific soil type and layering could be selected and customized to answer desired questions. Sensors were placed in the exact position desired and extracted during excavation without damage to use in subsequent testing. CPTs were performed multiple times before and after driving and restrikes using the miniature cone penetrometer. Testing performed in the field usually consist of a single sounding made before driving. Overall, the developed laboratory experiment was found to be more economical, controlled, and efficient than full scale testing.

Download or read book Electrical Measuring Instruments and Measurements written by S.C. Bhargava and published by CRC Press. This book was released on 2012-12-27 with total page 1888 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written for the benefit of engineering students and practicing engineers alike, is the culmination of the author's four decades of experience related to the subject of electrical measurements, comprising nearly 30 years of experimental research and more than 15 years of teaching at several engineering institutions. The unique feature of this book, apart from covering the syllabi of various universities, is the style of presentation of all important aspects and features of electrical measurements, with neatly and clearly drawn figures, diagrams and colour and b/w photos that illustrate details of instruments among other things, making the text easy to follow and comprehend. Enhancing the chapters are interspersed explanatory comments and, where necessary, footnotes to help better understanding of the chapter contents. Also, each chapter begins with a "recall" to link the subject matter with the related science or phenomenon and fundamental background. The first few chapters of the book comprise "Units, Dimensions and Standards"; "Electricity, Magnetism and Electromagnetism" and "Network Analysis". These topics form the basics of electrical measurements and provide a better understanding of the main topics discussed in later chapters. The last two chapters represent valuable assets of the book, and relate to (a) "Magnetic Measurements", describing many unique features not easily available elsewhere, a good study of which is essential for the design and development of most electric equipment – from motors to transformers and alternators, and (b) "Measurement of Non-electrical Quantities", dealing extensively with the measuring techniques of a number of variables that constitute an important requirement of engineering measurement practices. The book is supplemented by ten appendices covering various aspects dealing with the art and science of electrical measurement and of relevance to some of the topics in main chapters. Other useful features of the book include an elaborate chapter-by-chapter list of symbols, worked examples, exercises and quiz questions at the end of each chapter, and extensive authors' and subject index. This book will be of interest to all students taking courses in electrical measurements as a part of a B.Tech. in electrical engineering. Professionals in the field of electrical engineering will also find the book of use.
