Incorporating Corrosion in Reliability-Based Design of Anchored Bulkheads
Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from...
Sensitivity Evaluation of Simulation Methods for Reliability Assessment
Commonly used reliability assessment methods include the first-order methods, second-order methods, and Monte Carlo simulation methods with or without variance reduction techniques. The...
High Order Statistics in Structural Reliability
The new simulation technique described in this paper attempts to avoid the significant amount of arbitrariness involved in the choice of the sampling distribution in the increasingly popular...
A Mathematical Tool Set for SORM Reliability Methods
FORM and SORM methods are used for approximating failure probabilities. Here an overview of the main mathematical results of SORM methods is given: Classification of asymptotic behavior,...
Experiences with Experimental Design Schemes for Failure Surface Estimation and Reliability
When using FORM and SORM to predict the probability of failure for a structural component a model for the failure function has to exist. For certain structural components a mechanical...
On a Procedure to Estimate the Reliability of Mechanical Components
A procedure, based on the response surface concept is suggested to estimate the failure probability of mechanical components and structures under static as well as dynamic loading conditions....
An Advanced First-Order Method for System Reliability
This paper proposes an iterative first-order method for accurate estimation of the joint failure region of two nonlinear limit states. Current methods use either a first-order approach...
A Systems Reliability Approach to the Safety of Steel Connections
A methodology is presented to determine the probability of failure of steel connections using a systems approach. Results indicate that connection safety evaluations which do not use this...
Structural Reliability and Failure Mechanism Determination Using Monte Carlo Simulation with Variance Reduction Techniques
The objective of this paper is to present a possible method for assessing a structure's reliability and determining the collapse mechanism using Monte-Carlo simulation with variance reduction...
A Two-Stage Safety Assessment Methodology for Construction Activities
The control of construction activities requires the evaluation of the condition of the control attributes of interest. In order to develop the required methodology, a model of the construction...
Risk Based Structural Optimization
Risk based structural optimization problems for structural systems are formulated on basis of a so-called risk index. The risk index is defined as a consequence modified reliability index...
Stabilizing Drop Structure by Drainage Modifications
East Drain Terminal Drop Structure is located in East Drain, an open toe drain of Palmetto Bend Dam, in the tide water area of south Texas. The drop structure was threatened by piping...
Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...
Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...
Seismic Rehabilitation of Seattle's Pier 69
The Port of Seattle, one of the largest on the west coast of North America, made a strong statement regarding their support for reusing existing structures when a decision was made to...
West Point Temporary Construction Dock
The West Point temporary construction dock is designed to provide construction access for the West Point treatment plant project located in Seattle, Washington. The dock plays a major...
Wetland Restoration and Creation Guidelines for Mitigation
The majority of wetland mitigation projects built in the U.S. are failures. Reasons for failure include poor siting, improper design (including inadequate baseline data collection), inadequate...
Building a Pipeline?Not a Flow Through Process
This paper will illustrate that the planning, design, and construction of a 32-mile water supply pipeline from Stockton Lake to Springfield involves more than just digging a trench, placing...
Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...
Design Criteria and Specifications for Pipeline Rehabilitation Projects
Pipeline rehabilitation, while not a completely new technology, is nevertheless a fairly recent development, just now coming to the forefront as to common usage. It is not however a fail-safe...
