Waste to Energy? The Burning Question
For all their bad press, waste-to-energy plants actually provide a one-two environmental punch�they reduce garbage volume and provide alternative energy. But increasingly, state and local...

Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Seismic Hazard Estimation in the Eastern U.S.
Probable seismic hazard is generally estimated considering five elements: 1) seismicity; 2) source radiation; 3) wave propagation (attenuation); 4) site response; and 5) ground failure....
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
Development of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base, which is still growing, currently contains information...
Simple Damage Predictors for Large-Scale Seismic Risk Mapping
Although it is now recognized that there is a risk of moderate seismic activity in the Eastern United States, many existing buildings were not designed for earthquake forces. To evaluate...
Simulation of Seismic Damage of RC Structures in Eastern US
A normalized index for evaluation of structural damage was developed based on the relation of demand and capacity. The proposed formulation combines two sources of damage: permanent deformation...
Serviceability of San Francisco Auxiliary Water Supply System
A method is developed for estimating the seismic serviceability of water supply systems. The method can account for uncertainties in earthquake, mechanical properties of soil and pipelines,...
Dynamic Stability of Cable Domes
The cable domes designed by David Geiger for the gymnastics and fencing arenas for the Olympics at Seoul, Korea, and for the stadium at St. Petersburg, Florida, are geometrically non-linear...
Model Identification of an Arch Bridge for Dynamic Analysis
The dynamic responses of a steel deck tension-tied arch bridge subjected to earthquake excitations were investigated. The 189 m (620 ft) Birmingham Bridge located in Pittsburgh, PA was...
Reliability Analysis for Nonlinear Limit States
An analytical procedure, incorporating individual probability distributions of random variables, is proposed for generating moments of any arbitrary order for the nonlinear limit state...
On the Application of Conditional Integration in Structural Reliability Analysis
An accurate, and efficient computational procedure is proposed for structural reliability analysis. The suggested advanced Monte-Carlo simulation utilizes the concept of conditional integration...
Optimization of Structures Under Stochastic Loads
A method for design under multiple stochastic loads based on optimization is developed. The objective function such as cost is minimized under the constraint that the probabilities of...
Limit States Reliability Interaction in Optimum Design of Structural Systems
A multiobjective optimization approach to deal with structural reliability-based design under multiple limit states is developed. This approach resolves the limit states reliability interaction...
Structural Optimization Based on Component-Level Reliabilities
A minimum-weight optimum design procedure is proposed including the reliabilities of various elements in a structure as constraints. The reliability indices corresponding to the various...
Present and Future Developments in Steel Design Codes
Steel structures design codes with load and resistance factors (or 'partial factors') which are based on first-order probabilistic concepts are now in use in...
LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....
