Significance of Spatial Variability of Deep Cement Mixed Columns on Reliability of Column-Supported Embankments
Publisher: American Society of Civil Engineers
Abstract: The spatial variability of mechanical properties of deep cement mixed (DCM) soil leads to uncertainty in performance of DCM column–supported embankments. While adequate safety levels can be achieved using a large factor ...
Seismic Lateral Response of Piles in Liquefying Soil
Publisher: American Society of Civil Engineers
Abstract: Soil liquefaction is one of the major factors affecting the behavior of piles founded in seismically active areas. Although methods are available for seismic analysis of pile foundations, in many of them, the supporting ...
Pseudostatic Approach for Seismic Analysis of Piles in Liquefying Soil
Publisher: American Society of Civil Engineers
Abstract: The performance of pile foundations during an earthquake significantly influences the integrity of structures supported by them. Therefore, in the overall seismic design process of the structures, modeling of the ...
Analytical Solution for the Consolidation Behavior of Deep Cement Mixed Column–Improved Ground
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analytical solution for the consolidation behavior of deep cement mixed (DCM) column–improved ground on the basis of the equal strain condition. The proposed analytical solution accounted for the ...
Numerical Modeling of Nonhomogeneous Behavior of Structured Soils during Triaxial Tests
Publisher: American Society of Civil Engineers
Abstract: The nonhomogeneous behavior of structured soils during triaxial tests has been studied using a finite element model based on the Structured Cam Clay constitutive model with Biot-type consolidation. The effect of inhomogeneities ...
Effects of Wall Movements on Performance of Integral Abutment Bridges
Publisher: ASCE
Abstract: Abutment walls in integral abutment bridges (IABs) move in a cyclic pattern in response to temperature-induced expansion and/or contraction of the bridge superstructure. The repetitive abutment movements cause an active-wedge ...
