Guideline for Structural Condition Assessment of Existing Buildings
Changing economic conditions, concerns for historic preservation, emphasis on fully utilizing conveniently located structures, space shortages, and increasing cost of materials and products...
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...
Fly Ash for Hire
Each year, roughly 15 million tons of ash created by U.S. coal-fired powerplants is recycled. Most is used in concrete and other construction materials, such as structural fill, but utilities,...
Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Reliability of Overhead Transmission Lines Subjected to Wind Action
The probability distribution of the strength of steel towers used in transmission lines, due to wind excitation, is evaluated on the basis of test results of 72 towers of various designs,...
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...
Variability of Parameters of Earthquake Ground Motion Recorded by Strong Motion Arrays
The spatial variation of scalar measures of earthquake ground motion, such as peak ground acceleration, strong motion duration, and root-mean-square amplitude, along with various spectral...
Identification of a Site-Specific Ground Motion Model
The power spectral density and envelope function of earthquake ground accelerations at a site of interest are determined with the aid of system identification based on information predicted...
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...
Earthquake Energy Partitioning in Base Isolated and Dynamically Damped Structures
New earthquake energy spectra are proposed for practical design procedures using energy concepts. The spectra show integrated earthquake input energy of a unit mass with given natural...
Application of Physical Laws to Parameter Estimation for Probabilistic Models of Cumulative Damage
In this initial paper we will discuss the development of the application of physical laws to the modeling of cumulative damage and particular to crack growths. The basic assumptions due...
Damage Evolution in Reinforced Concrete Members Under Cyclic Loading
The paper presents a new damage indicator D, valid for reinforced concrete sections under cyclic loading. DQ, based on sectionally absorbed energies,...
A Topology Variational Method for Reliability Analysis of Structural Systems
A force method of structural analysis, named topology variational method, is used to compute the reliability of plastic framework. The system failure is defined in terms of a global response...
On the Failure Probabilities of R/C Chimneys
A procedure to estimate failure probabilities of structural systems such as reinforced concrete (R/C) chimneys under severe wind loading which allows for considering realistic correlation...
Reliability of Identical Brittle Parallel System
The failure path of a system can be investigated through the use of a failure graph, which is a directed graph of all possible sequences of element failures. This paper describes the development...
Durability and Damage Tolerance Evaluations of Jet Transport Structures
Many design considerations are involved in ensuring structural integrity of Boeing jet transports, which have common design features validated by extensive analyses, tests, and service...
Local Integration Method in Stochastic Finite Element Analysis
This paper, introducing local integration method, proposes a new stochastic finite element method for estimating the response variability of multi-dimensional stochastic systems. Young's...
