The journal will meet the needs of the researchers and engineers to address risk, disaster and failure-related challenges due to many sources and types of uncertainty in planning, design,...

Railway Geotechnical Asset Management in Great Britain: How Modern-Day Techniques Help Monitor Railway Infrastructure Dating to the 1800s
This article discusses asset management, risk management, and earthworks failures as experienced by Network Rail (NR), the owner, operator, and asset manager of the majority of the rail network of Great...

Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...

Remote Sensing: A New Revolution in Geotechnical Engineering
Remote sensing in the form of satellite imagery has become part of our everyday life—from displaying boring locations at a job site to the various mapping apps on our smart phones that help us get there....

Answering the $64,000 Question: Geotechnical Risk in Design-Build Projects
Subsurface risk may well be the aspect of most construction projects that has the greatest potential impact on a project's success or failure. Even when a thorough geotechnical investigation is conducted...

Post-Earthquake Reconnaissance Using Digital Imagery
A Bird's-Eye View
Over the last decade, remote sensing has played an increasing role in geotechnical earthquake reconnaissance through the use of satellite imagery, LIDAR, and unmanned aerial vehicles (UAVs). These techniques...

Nature Sides with the Hidden Flaw: Lessons Learned from Failures of Earth-Support Systems
In recent years, the demand for excavations and fills of significant height has increased due to many factors, including requirements for below-grade parking for urban buildings and the need to construct...

The 2010-2011 Canterbury, New Zealand, Earthquake Sequence
Impetus for Rethinking the Way We Evaluate and Mitigate Liquefaction
Liquefaction is a common cause of ground failure during earthquakes and is directly responsible for tremendous damage to infrastructure. Evidence of the impact of liquefaction includes failure of bridge...

Emergency Retaining Wall Replacement: The East 26th Street Slide Repair in Baltimore, MD
During a record rainfall on April 30, 2014, a century-old, stone retaining wall between a dense urban roadway (26th Street) and the CSXT railroad track in Baltimore, MD, failed. The stone retaining wall...

Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...

Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...

A Light in the Deep: The Future of Offshore Site Investigations
For deep-water energy developments, hazard identification and risk assessments (that is, assessing the probability of occurrence along with the consequences of failure) are more important...

Interactive Graphics Dynamic Analysis of Frames

Dynamic Stresses From Experimental and Modal Analyses

Dynamic Analysis of Equipment Structure Systems

Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....
