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....
A Non-Gaussian Fatigue Model for Offshore Structures
Fatigue damage accumulation in members of offshore structures can be affected by various aspects of the non-Gaussian response stress time history induced by the nonlinear/non-Gaussian...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
Reliability-Based Specification of Design Load-Effect for Penetrating Fragments and Debris
This paper presents the derivation and application of a simplified reliability-based approach for selecting design fragments/debris particles for use in protective design. Using this approach,...
Time-Variant System Reliability Analysis Using Response Surface Methodology and Fast Integration
An approximate method is presented to solve the structural reliability problem of complex structural systems subjected to time-variant loads where the parameters of the structural system...
First-Excursion Probability of Uncertain Structures
The first-order reliability method (FORM) is used to estimate the first-excursion probability of uncertain structures subjected to deterministic dynamic loads. An algorithm is developed...
Critical Buckling Load Statistics of an Uncertain Column
The objective of this paper is to examine the statistics of the buckling load of a column with uncertain material properties. The elastic modulus is assumed to be a random process that...
Bridge Overloading Criteria
Considerable concern is being expressed by the public and government agencies over the deteriorating state of the country's infrastructure. At the same time, there is a general feedling...
A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....
Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...
Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...
Targeting of AgI in a Utah Winter Orographic Storm
A cooperative research program among the Utah Division of Water Resources, the National Oceanic and Atmospheric Administration, and the Bureau of Reclamation has investigated targeting...
Pile Lateral Load Test in the Port of Los Angeles
Recent wharf projects in West Coast ports have featured rock dikes to contain backland fill and the use of vertical piles embedded in the rock dikes to resist lateral loads. This paper...
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...
Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...
Bulk Commodity Terminals?Planning for the Future Competitive and Environmental Challenges
The demand upon all industries for better protection of the environment is increasing and the regulations and permit requirements are changing rapidly. Bulk commodity terminal operators...
Floating or Fixed Dock for RO/RO Ship Operations
Floating pontoon-type dock structures are typically used for RO/RO ship berthing. Primary advantage of a floating dock for RO/RO berthing is the relatively constant height relationship...
Model Tests for Expansion of Anaheim Bay Naval Harbor
Modifications to the Anaheim Bay, California, Harbor complex have been proposed to enable larger ships to access the existing wharf for direct loading of ordnance. In addition, new deepwater...
Loading of Nutrients to Groundwater From High Source Areas During the Winter Period
Nutrient loading to surface, subsurface and groundwater in agricultural areas is the focus of control programs throughout the United States. In certain cases, high source areas can be...
