Structural Engineering in the 21st Century
This proceedings,
Electrical Explorations (Available in Geo-Environmental Special Issue only)
Recent advances in state-of-the-art, relatively fast, two- and three-dimensional electrical resistivity imaging (also called profiling or tomography) have offered a new view on subsurface...
Structural Design for Physical Security
State of the Practice
Prepared by the Task Committee on Structural Design for Physical Security of ASCE. This report provides guidance to structural engineers in the design...
Sky High
The increasing demand for personal communication services (PCS), such as digital cell phones and pagers, as well as digital television (DTV), has created new challenges for creating and...
On Solid Ground (Available only in the Geoenvironmental Special Issue)
On four transportation projects in Portland, Ore., soil nails and micropiles are used as alternatives to conventional earth-retention and foundation systems. The use of soil nails and...
Seismic and Dynamic Analysis and Design Considerations for High Level Nuclear Waste Repositories
This committee report was created to fulfill two primary objectives: 1) to provide guidance for assessing and defining the dynamic loads that must be considered in the design of a repository...
Design of Hydraulic Steel Structures
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 22 This manual prescribes guidance for designing hydraulic...
Wind Endurance
Although property casualty insurance companies are interested in a building's resistance to intense winds, risk underwriters traditionally take into account few, if any, wind-performance...
Examples
This section includes several examples that illustrate many of the concepts presented in this guide. The examples and load cases have been simplified and may not represent actual design...
Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...
Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...
Chicago's Micropile Debut
On a tight, urban site around Chicago's historic Orchestra Hall, engineers used high-capacity micropiles as an alternative to hand-dug caissons. On a $104 million project...
Seismic Design Doubles Lateral Resistance (Available only in
A veterans hospital in Palo Alto, Calif. had to be built under severe design constraints. The seismic code for hospitals is among the most stringent of codes and this facility was sited...
Reliability and Response Control of R/C Buildings
A damage model is summarized for the assessment of seismic damage of reinforced concrete structures. The model is to evaluate specific buildings that were damaged in Mexico City during...
Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...
Distributional Information for Ejection Fragments
Due to lack of experience of building structures on the lunar surface and the variability that will exist in the loading as well as the structural resistance, it is suggested that initial...
Preserve and Protect
Historic and landmark structures constructed of unreinforced masonry and stone are among the most vulnerable to strong ground shaking and are often subject to possible collapse. For the...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
