A method is presented for evaluating the lifetime risk of failure, in terms of probability of excessive inter-floor deflection, for a class of steel building frames subjected to dynamic...

Automated Damage-Controlled Design of RC Buildings
This paper presents an automated damage-controlled design method, which aims for uniform damage distribution throughout the entire building frame while respecting the strong-column weak-beam...

Pipeline Field Experiment at Parkfield, CA
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed near Parkfield, CA. The site was chosen to capitalize on the predicted...

Response Analysis of Crude Oil Transmission Systems
A preliminary analysis of the seismic response of continuous steel pipelines is presented. The Crude Oil Transmission System in the New Madrid Mo. area is choosen as an example. Assumptions...

A Continuous Damage Index for Seismic Reliability Assessment of Structural Steel Elements
Based on experimental investigations using steel plate elements subjected to cyclic axial loading, a continuous damage and/or deteriorating process is examined. In order to describe intermediate...

Load Path Dependence of Structural Systems
This paper presents the results of an investigation into the sensitivity of the behavior of framed structures to load path. Simple but realistic structural steel frames have been designed...

Safety Evaluation of a Tall Building
This paper uses the extended Kalman filter to perform the system identification of a tall building with the aid of recorded accelerograms obtained from strong-motion seismographs. The...

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...

Statistical Fatigue Properties of Carbon Steels for Machine Structural Use Based on JSMS Database on Fatigue Strength of Metallic Materials
A database on the fatigue strength of metallic materials was compiled by collecting the experimental fatigue data of the last 20 years in Japan on a nationwide scale as a joint project...

Distribution of Variance of Fatigue Lives of Ferrous Metals by the Analysis of Fatigue Strength Database
The purpose of this study is to determine the distribution characteristics of variance of fatigue lives of carbon and alloy steels, especially from the viewpoint of their dependence on...

Fatigue Reliability of Steel Structures in the Presence of Residual Stresses
An extended model for the assessment of fatigue reliability of steel structures in the presence of residual stresses is developed. The model explicitly includes the uncertainties of the...

Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...

Fatigue Reliability of Prestressed Concrete Bridges
Experimental studies indicate that fatigue is a random phenomenon. Therefore, the approach is based on probabilistic methods. The fatigue life of the prestressed concrete girder is estimated...
