Generalized Bounding Surface Model for Cohesive Soils: a Novel Formulation for Monotonic and Cyclic Loading
By: Andres Nieto Leal Chair: Victor N. Kaliakin
ABSTRACT
Constitutive models have been developed to simulate the soil response under different loading conditions. Within the wide spectrum of these conditions, earthquakes have been of interest to the research community worldwide. Traditionally, researchers have largely focused on simulating the response of cohesionless soils. Such soils, when subjected to earthquake loading, may experience the well-known phenomenon of liquefaction, which has led to much destruction in different parts of the world. By contrast, far less research has been done on simulating the response of cohesive soils subjected to cyclic loading. Consequently, certain issues associated with the simulation of such response are still being addressed. One of the biggest concerns during an earthquake is the amplification of seismic waves through a deposit of cohesive soil, which will result in significant ground movements, thus requiring higher levels of seismic resistance from the structures founded on such soils.
A review of experimental results has identified several key characteristics of cyclically loaded cohesive soils that any rational mathematical simulation must account for. Accordingly, the scope of this dissertation is the development of an improved and generalized elastoplastic bounding surface model that is suitable for simulating the general response of cohesive soils, with emphasis on cyclic loading.
