A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...
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,...
Project Layout
Microtunneling projects should be laid out with attention to the benefits and constraints unique to this construction process. The following recommendations address some of these concerns:...
Shaft Considerations
Jacking and receiving shaft locations should be selected to minimize the number of shafts and disruptions while not exceeding the practical limits of the drive lengths achievable for a...
Shafts/Temporary Structures
Shafts should be of a size to accommodate the equipment and pipe selected and to allow for safe working practices. If the shaft must accommodate the permanent works, it is the contractor's...
Shear and Interface Strength of Clay at Very Low Effective Stress
Thin-specimen direct shear (TSDS) tests were conducted to measure the shearing strength of kaolinite, and interface strengths between kaolinite and acrylic plastic and anodized aluminum,...
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...
Finite Difference Analyses for Sand Drain Problems
The geotechnical literature contains a number of papers in which sand drain installations are described and field performance is compared with theoretical predictions. Some of the field...
Structures Congress 2012
Forging Connections in the Windy City
Proceedings of Structures Congress 2012, held in Chicago, Illinois, March 29-31, 2012. Sponsored by the Structural Engineering Institute of ASCE. Structures Congress 2012 contains 202...
Size and Scale Effects on the Shear Strength of Concrete Beams
This paper identifies and discusses the role of proper geometric scale of relevant parameters in the size effect in shear, particularly in terms of practical beam design. In the overall...
Port of Los Angeles Risk Management Strategies
This paper examines risk management strategies for the port of Los Angeles. Topics include its importance to the economy, potential port risks, seismic risk strategies, and terrorist risk...
Marginal Permafrost a Foundation Material in Transition
At the edges of the world's cold regions lie areas of marginal permafrost. It is a changing landscape that seems to be growing in extent, yet it retains chameleon-like qualities...
Refrigerated Foundations
Refrigeration systems used to cool foundations on frozen ground can be classified as either active or passive, depending on whether external energy is used to power the systems. If pumps,...
Seismic Calculation and '97 UBC
This chapter discusses seismic calculations in Microsoft Excel....
Symbol of Strength
Shortly after the Oklahoma City bombing, the federal government decided to rebuild. The result is an architectural gem incorporating the latest advances in blast resistance and sustainable...
Fundamentals of Seismic Isolation
This chapter examines fundamentals of seismic isolation, including its principles, history, and examples of seismically-isolated structures....
San Diego Delivers
To maintain its ability to provide water to some of its rapidly growing regions, the city of San Diego is simultaneously laying two large diameter pipelines, one carrying potable water...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Water and Wastewater Seismic Vulnerability Assessment and Loss Mitigation Overview
The basic steps of a loss mitigation program for water and wastewater systems are briefly described in this section. These steps demonstrate how the checklists may be used to compliment...
