Reliability Analysis for Offshore Structures
This study presents the reliability analysis of an offshore structure. The mechanical model includes various elasto-plastic diagrams with and without the combination of the normal force...

Correlated Non-Gaussian Models in Offshore Structural Reliability
Correlated non-Gaussian models of offshore loads and responses are developed. These require only correlation coefficients and either marginal distributions or moments. Simple estimates...

Reliability Analysis of Offshore Structures Using the Virtual Distortion Method
This paper describes a new and efficient methodology for structural reliability analysis applicable to offshore jacket structures. The proposed methodology uses the Virtual Distortion...

Autocorrelation Functions for Offshore Geotechnical Data
Autocorrelation functions are described. Data from several North Sea sites are analyzed with respect to the vertical and horizontal autocorrelation of a number of soil properties. Based...

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 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....

Graphic Demonstration 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 presently holds five categories of data, the largest of...

Near-Field Differential Ground Displacement
An analytical model for the development of differential ground motions in the vicinity of a vertical, strike-slip fault is presented. The model considers a uniform, kinematic source model,...

Global Damage Indices and Nonlinear Structural Response
Damage indices based on equivalent linear parameters have been proposed for the analysis of global seismic damage. The analysis of shaking table experiments and strong motion records has...

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...

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...

Seismic Fragility Analysis of Shear Wall Structures
This paper presents an analytical method to generate seismic fragility curves for shear wall structures. Uncertainties in earthquake motion and structure are quantified by evaluating uncertainties...

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...

Response Modification Factors for Buildings and Bridges
Response Modification Factors (RMF) are often used for the seismic design and the safety evaluation of buildings and bridges. The advantage of using RMF is to account for the nonlinear...

Seismic Response of Structures and Reliability Design
This paper develops a modified SRSS Method which allows a designer to select the reliability that he wishes to realize in each of the various elements of a given structure subjected to...

Wind Vs. Seismic Design
This paper is concerned with the reliability analysis of building structures subjected to multiple natural hazards (seismic and wind in this case) within the framework of contemporary...

Reliability-Based Design Codes
Reliability analysis for code-designed simple structures subjected to earthquake loading are being determined using both static and dynamic methods and strength-based and damage-related...

Multi-Hazard Risk Assessment of an Offshore Structure
This paper develops and illustrates a methodology for multi-hazard modal risk assessment. The case study involves assessing risk to an offshore structure in a load environment consisting...

Iterative Subsystem Analysis for Seismic Monte Carlo Studies
Three iterative subsystem analysis techniques for Monte Carlo simulation of response time histories are examined. The three subsystems are designated primary, secondary, and interface,...

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...
