Cyclic Capacity of Monopiles in Sand under Partially Drained Conditions: A Numerical Approach
(American Society of Civil Engineers, 2023/02/01)Cyclic loading of saturated sand under partially drained conditions may lead to accumulated strains, pore pressure buildup, and consequently reduced effective stress, stiffness, and shear strength. This will affect the ... -
Performance of a Belled Pile Influenced by Pile Head Freedom Response to a Cooling–Heating Cycle
(American Society of Civil Engineers, 2023/02/01)This paper demonstrates the influence of pile head freedom on the thermomechanical performance of a belled pile. Field tests on the belled pile response to a cooling–heating cycle and incremental structural construction ... -
Empirical Assessment of Liquefaction Resistance of Crushable Pumiceous Sand Using Shear Wave Velocity
(American Society of Civil Engineers, 2023/02/01)Sands consisting of pumice particles are found in the northern part of the North Island of New Zealand. These pumice sands are highly crushable, compressible, and lightweight due to the vesicular nature of the particles, ... -
A Revised Porous Media Model of Microbially Induced Carbonate Precipitation for Loess Solidification
(American Society of Civil Engineers, 2023/06/01)Similar to sand solidification with microbially induced carbonate precipitation (MICP), the MICP technique can also be used to bond loess particles and improve the collapsibility of loess. However, existing theoretical ... -
