The Body Language of Tensile Structures
Considered to be a 'body' and its visual appearance as 'non verbal, intuitable information,' a building has a Body Language that is employed as a primary mode. Presented is an intuitive...

Tensegrity Structures: Filling the Gap Between Art and Science
Underlining the role of structuralism in contemporary architecture this paper addresses the application of structural morphology in the context of an educational experience. Focussing...

How to Optimize Light-Gage, Cold-Formed Steel Beams
The Illustrative Examples section of the AISI Cold-Formed Steel Design Manual (AISI 1989) demonstrates how to analyze a number of different cold-formed steel sections. This paper applies...

Structural Analysis for Structural Design
This paper presents a simple extension to conventional structural analysis that serves to provide additional information that is of significant use to the structural design process. Specifically,...

Torching Soils Increases Strength and Stiffness

Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...

Settlement Analysis of Landfill Liners over Deep Mined Areas
Tensile strains due to differential settlement from past mining activities were evaluated for a landfill liner. The landfill cell encompasses 20 acres and is located on a subsurface profile...

Settlement Predictions at a Florida Port Facility
A paved container storage area approximately four acres in size has been constructed at the existing Port of Fernandina in Fernandina Beach, Florida. Approximately one-half of the site...

Nonlinear Undrained Lateral Response of Rigid Drilled Shafts Using Continuum Theory
The nonlinear undrained response of rigid drilled shafts under static lateral and moment loading is evaluated within the context of elastic continuum theory. The approximate approach utilizes...

The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...

High-Performance Concrete Incorporating Large Volumes of ASTM Class F Fly Ash

Selected Properties of High Performance Concrete

Metakaolin Increases Strength and Lowers Permeability of High Performance Concrete

Estimation of the Thickness of Transition Zone in Concrete and Characteristics of Transition Zone in High-Strength Concrete

A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....

Practical Method for Scour Prediction at Bridge Piers
A practical method is presented for prediction of local scour at bridge piers which is based on a comparison of many well known equations and supported by field data. This equation includes...

Comparison of Headcut Advance Testing and Soil Test Results
This paper presents the results of a study conducted in a flume to determine headcut advance rates of two base soils compacted at various compaction moistures and placement energies. The...

Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
