The investigations: The World Trade Center towers
On Aug. 21, 2002, the National Institute of Standards and Technology announced it would conduct a building and fire safety investigation of the World Trade Center disaster. This investigation was conducted...
Poison Oak, Mistakes, and Lessons
When things go wrong in geotechnicalengineering ? like ground movements andearthwork construction delays ? failureinvestigations are often performed. In a typical geotechnical project, the path is relatively...
ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
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, analysis, construction,...
Evaluating Bridges With Unknown Foundations for Susceptibility to Scour: North Carolina Applies Risk-Based Guidelines to Over 3,750 Bridges
Scour occurs when flowing water removes erodible material such as sand and rock. For bridges over water, scour affects the stability of pier and abutment foundations and contributes to...
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...
Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...
Failure of a Large Circular Excavation
A circular excavation, 117 feet (36 m) in diameter by 90 feet (27 m) deep, was designed by an experienced engineering firm and construction was performed by an experienced contractor....
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....
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,...

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...
Toward a Unified Approach to Anchorage in Reinforced Concrete Design
The introduction of rationalized design procedures for cast-in and post-installed anchors inEurope and the U.S. was intended to provide a uniform factor of safety for anchorages inconcrete,...
The Levees Fail
This chapter examines the failure of levees against storm forces and the flooding that ensued....
Direct Causes of the Catastrophe
This chapter examines direct physical causes of the hurricane protection system failures, including soil strength assessments and pumping station limitations....
Contributing Factors
This chapter examines contributing factors of the hurricane protection system failures, including the underappreciated risk to New Orleans, a piecemeal implementation of the hurricane...
Strong Diagonals
Exterior Diagonal Systems that carry both gravity and lateral loads in building structures � known as exodiagonals or diagrids � are increasingly being used worldwide to provide freedom...
