Air-Water Mass Transfer
This monograph, Air-Water Mass Transfer: Selected Papers from the Second International Symposium on Gas Transfer at Water Surfaces, consists of papers presented at the Symposium which...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Knowledge Acquisition in Civil Engineering
Expert systems are an intriguing approach for transferring valuable problem-solving skills from the minds of human experts to the logic of computer programs. For the past several years,...

Freudenthal Lecture Developments in Structural Reliability
Rather than reviewing the details of developments in structural reliability theory and its implementation over the last few decades, more recent and more relevant reliability issues are...
Reliability of Large Technological Systems
Codes and regulations regarding large technological systems of growing complexity should take into account the increasingly sophisticated analysis tools that have been and are being developed...
Man and Huge System Interaction
In many cases of disaster, the causes of failure of huge systems are frequently attributed to human error. However human is liable to error. To exclude human factor from a huge system...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
Stochastic Behavior of Concrete Arch Dam-Reservoir Fluid-Foundation Systems in Nonstationary Random Vibration
The behavior of elastic arch dam reservoir fluid system subjected to ground acceleration excitations has been studied extensively by Chopra and his colleagues. In their studies, the excitations...
Seismic Ground Motions for Lifeline Analysis
The spatial variation of seismic ground motions necessary for lifeline analysis is determined from a stochastic source model combined with a substitute system representing the equivalent...
Reliability and Design Criteria for Secondary Systems
In seismic design and analysis of secondary systems housed in structures, the most widely used approximate method is the floor response spectra approach. In this paper, necessary modifications...
On Aseismic Hybrid Control System
One type of hybrid control system is proposed for protecting tall buildings subjected to strong earthquakes. The hybrid system consists of a base isolation system connected to either a...
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,...
Serviceability of Water Transmission Systems
This present paper deals with the vulnerability and reliability of a functionally as well as physically hierarchical lifeline system. Most major lifeline systems have this feature. For...
Graphical Demonstration of Serviceability Analysis
A graphical interactive computer program (GISALLE) has been developed using state of the art computer graphics to estimate the seismic performance of water supply systems. GISALLE is developed...
Lifeline Systems Reliability, Serviceability and Reconstruction
In this paper we present a brief outline of methods and results for characterizing the reliability and serviceability of oil pipeline systems. Further, we present an outline of methods...
Critical Seismic Excitation for Structures
Critical seismic excitations are defined as stationary random functions with a given variance, which maximize the response variance of a linear structural dynamic system. A method is presented...
The Application of Reliability Based Design for Earthquake Resistant Communications Structures
Current earthquake design criteria consists of applying equivalent lateral static forces embodied in design codes. The structures designed in conformance with such provisions and principles...
A Practical Model for Forecasting Water Supply Functions at Time of the Earthquake
This study aims to construct a practical forecasting model for the seismic damage restoration of city water supply functions by using experts empirical knowledge as well as the functional...
