RISUpper Bound for Cylinder Movement Using “Elastic” Fields and Its Possible Application to Pile Deformation Analysis
Publisher: American Society of Civil Engineers
Abstract: A new upper bound failure mechanism for the problem of rigid cylinder motion is presented. The velocity field associated with the mechanism is derived from a known elastic solution by similitude of the deformation field. ...
Discussion of “Evaluation of Undrained Shear Strength Using Full-Flow Penetrometers” by Jason T. DeJong, Nicholas J. Yafrate, and Don J. DeGroot
Publisher: American Society of Civil Engineers
Enhanced Strain-Softening Model from Cyclic Full-Flow Penetration Tests
Publisher: American Society of Civil Engineers
Abstract: This paper presents a systematic approach for relating fundamental (soil element) strength-degradation models with cyclic full-flow penetration tests. The approach is then employed to enhance the commonly-used exponential ...
Detection of Sinkhole Formation by Strain Profile Measurements Using BOTDR: Simulation Study
Publisher: American Society of Civil Engineers
Abstract: The sudden collapse of sinkholes in the Dead Sea area represents a serious threat to infrastructure in the area. The formation of these sinkholes has been shown to be directly correlated with the drop in the Dead Sea water ...

Abstract: This paper presents a systematic approach for relating fundamental (soil element) strength-degradation models with cyclic full-flow penetration tests. The approach is then employed to enhance the commonly-used exponential ...
Three-Dimensional Analysis of Lateral Pile Response using Two-Dimensional Explicit Numerical Scheme
Publisher: American Society of Civil Engineers
Abstract: A procedure for exploiting a two-dimensional (2D) explicit, numerical computer code for the 3D formulation of dynamic lateral soil-pile interactions is considered. The procedure is applied to two models using simultaneous ...
Damage Identification in Reinforced Concrete Beams Using Spatially Distributed Strain Measurements
Publisher: American Society of Civil Engineers
Abstract: Brillouin optical time domain reflectometry or analysis (BOTDR/A) is one of the strain measurement technologies that is suitable for smart monitoring of civil engineering infrastructures. Although the technology has the ...

Simple Energy-Based Method for Nonlinear Analysis of Incompressible Pile Groups in Clays
Publisher: American Society of Civil Engineers
Abstract: This note presents a method for predicting nonlinear response of pile groups in clays, subjected to vertical loads. The method is based on mobilizable strength design (MSD) concepts, in which the mobilized strength is ...
Design Oriented Linear-Equivalent Approach for Evaluating the Effect of Tunneling on Pipelines
Publisher: American Society of Civil Engineers
Abstract: The process of tunneling is associated with ground movements which may lead to stressing of nearby existing buried infrastructure, and potentially poses a risk of damage. The need for an effective evaluation method of the ...
