Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

Guidelines for Construction Vibrations: How Much Rattle is Too Much?
The study of construction/blast-related ground vibrations on structures, people, and objects is a surprisingly diverse field. Vibration sources vary from blasting, all types of construction equipment,...

A History of Deep Vibratory Methods for Ground Improvement
A Cost-Effective Foundation Solution for 80+ Years
Deep vibratory ground improvement methods, collectively referred to as vibro systems, have been utilized by the construction community in one form or another for the past 80 years. Development of the equipment,...

You Designed It for the Big One, Right?
Illustrating and Communicating Uncertainty in a Deterministic Seismic Hazard Analysis
In seismic regions of the U.S. and worldwide, engineers design structures to withstand seismic ground motions resulting from a large, rare earthquake. But definitions of "large" and "rare" depend on who...

Instrumentation and Monitoring
A detailed plan for monitoring possible ground surface movements caused by the microtunneling operations should be prepared. The plan is typically prepared by the engineer in consultation...

Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...

High Explosive Simulation of Earthquake-Like Ground Motions

A Fault-Rupture Propagation Model for Ground Motion Simulation

On the Slow Motions of Tankers Moored to Single Point Mooring Systems

Response of Tension Piles to Simulated Seismic Motion in Saturated Fine Sand

Design of Isolated Structures
This chapter examines the design of isolated structures. Topics include governing design codes; design of isolated buildings; design of isolated bridges and viaducts; and issues related...

Power Shift
Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs....

Frozen Ground Engineering
This new edition gives a peerless presentation of soil mechanics for frozen ground conditions and a variety of frozen ground support systems used on construction project worldwide. An...

Design and Construction of the Pier J Breakwaters at the Port of Long Beach, California
Several different alternatives to mitigate surge activity were investigated. The most acceptable solution was a pair of new breakwaters that altered the basin geometry to change the basin...

Saving Saluda
One of the largest roller-compacted-concrete berms in the United States will stand sentinel in case South Carolina's Saluda Dam undergoes liquifaction in response to strong...

New Parameters to Model Ground Motions
The paper presents three new parameters to characterize earthquake-induced ground motions. All three parameters evolve from the concept of response spectra, and are termed 3D response...

Fragility Curves and Seismic Loss Estimation Methodologies Based on Insurance Data
Loss data for single family dwellings from the 1994 Northridge, California, earthquake were correlated with ground motion with the aim of determining ground motion-based fragility curves....

Twenty-First Century Terminal
The Port of Los Angeles is already the busiest container facility in the United States, and the eighth busiest in the world. In 2000 it handled some 112 million tons (102 million Mg) of...
