Available in PDF, EPUB and Kindle. Book excerpt: In order to perform constant-volume (equivalent to undrained) Direct Simple Shear (DSS) tests using either a wire-reinforced membrane or stacked rings as the zero lateral strain confinement system, the height (and thereby volume) of the test specimen must be maintained at a constant during shear. The change in vertical stress while maintaining constant specimen height during shear is equivalent to the excess pore pressure that would have developed in a truly undrained DSS test. Depending on the control capabilities of active height-control DSS devices and the stiffness of locked (passive) height-control DSS devices, the specimen height may not be perfectly constant throughout shear in some cases. This technical note presents the results of monotonic constant-volume DSS tests where the specimen height was intentionally varied during shear to demonstrate the effect on measured shear stress and vertical effective stress. Changing the test specimen height by 0.05 % (the maximum specified by ASTM D6528, Standard Test Method for Consolidated Undrained Direct Simple Shear Testing of Fine Grain Soils) affected the test results. The percentage deviations in the measured test results are greater for stiffer soil specimens, about 2 % for soft normally consolidated clay and more than 20 % for dense sand at failure.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The direct simple shear (DSS) test is commonly used to assess shear strength of soil, estimate liquefaction resistance, or calibrate constitutive models. However, constitutive models are calibrated assuming ideal simple shear stress conditions even though this is not achieved in the DSS test. Near frictionless vertical boundaries cannot develop the complementary shear stresses necessary for ideal simple shear conditions. Difficulties in maintaining constant height during undrained tests violates the constant volume assumption. The top cap holding the top of the specimen can rock (rotate) during shear also violating the assumed perfect simple shear conditions. Parametric studies were conducted to investigate the effect of contact friction between the soil and vertical boundaries, vertical compliance and top cap rocking on the results of undrained DSS tests. The study simulates an industry-standard SGI type simple shear device using a 3-D finite element model and an advanced plasticity model to capture soil behaviour.

This book was released on 2022-09-19 with total page 2417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 4th International Conference on Performance-based Design in Earthquake Geotechnical Engineering (PBD-IV) is held in Beijing, China. The PBD-IV Conference is organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering - Technical Committee TC203 on Earthquake Geotechnical Engineering and Associated Problems (ISSMGE-TC203). The PBD-I, PBD-II, and PBD-III events in Japan (2009), Italy (2012), and Canada (2017) respectively, were highly successful events for the international earthquake geotechnical engineering community. The PBD events have been excellent companions to the International Conference on Earthquake Geotechnical Engineering (ICEGE) series that TC203 has held in Japan (1995), Portugal (1999), USA (2004), Greece (2007), Chile (2011), New Zealand (2015), and Italy (2019). The goal of PBD-IV is to provide an open forum for delegates to interact with their international colleagues and advance performance-based design research and practices for earthquake geotechnical engineering.

Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.
