Load Resistance Factor Design of Aluminum Structures
Load and Resistance Factor Design (LRFD) is a reliability-based approach to design with uncertainty. It involves the explicit consideration of limit states, multiple load and resistance...
Bridge Live Load Models
This paper describes the analysis of weigh-in-motion data and the conclusions drawn. Statistical distributions of the effects induced in typical bridges due to single vehicle events are...
Reliability Assessment and Reliability-Based Rating of Existing Road Bridges
A practical reliability model for the safety assessment and rating of existing R.C. bridges are developed by explicitly incorporating the degree of deterioration and damages based on available...
On the Dynamic Response of Bridges by Oscillating Vehicles on Rough Surfaces
The spectral theory is applied to the response of bridges under a Poissonian stream of vehicles moving with constant speed over the bridge. The vehicles are modeled as oscillators with...
Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...
Verification of NESSUS Code on Space Propulsion Components
Application of probabilistic finite element method to the structural analysis of typical space propulsion components such as turbine blades and high pressure ducts is reported. The study...
Application of Probabilistic Reliability Analysis Methods to Ariane 5 Unequipped Booster Case
The paper demonstrates the capabilities of probabilistic structure analysis methods as a tool to support the design and manufacture of the Ariane 5 Unequipped Booster Case within a RAMS...
Space Station Freedom Pressurized Module Meteoroid/Debris Protection
Protection of spacecraft from the effects of a meteoroid/debris particle impact can add significant weight to the required structure. This paper discusses the meteoroid and debris environments...
Pressure Vessels for Space Station Freedom
Space Station Freedom (SSF) will utilize more than 10 different types of pressure vessels for storage of oxygen, hydrogen, nitrogen and mixed gases at operating pressures ranging from...
Reliability Consistent Load and Resistance Factors
A practical algorithm to find the partial safety factors consistent with target reliability in LRFD format is proposed. The method is based on Second Order Second Moment method and Reliability...
A Reliability Analysis of Aerospace Structures Subject to Thermal Mechanical and Flight Loads
Aerospace structures are subjected to various flight loads throughout their service life. In certain anticipated missions, significant thermal stresses will be generated through atmospheric...
Rethinking Flood Control Channel Design
Until recently, the standard method of flood control was channelization�converting a natural stream to a uniform channel cross section. But this single objective approach is coming under...
Unlocking Arena Gridlock
The Charlotte Coliseum features a $22 million reversible lane system, which provides easier access to and from 8,000 parking spaces. To improve access to the arena, a 3.6 mi road extension...
HELP is on The Way
Hill and Davies describe current progress on the development of a Heavy Vehicle Electronic License Plate (HELP) system in the United States. The HELP system concept combines automatic...
Pilot Bore Pays Off
The primary purpose of tunneling through Cumberland Mountain is to ease the 18,000 vehicle per day traffic through the rugged terrain that was a major transportation route when Daniel...
Buried Structural Capacity of Insituform?
In July 1988, a test was conducted at Utah State University to determine the structural support that can be provided to a failing rigid pipe system through the use of the Insituform process....
Innovative New Drainage Pipe
Hydraulic tests on corrugated HDPE pipe with a smooth liner show that its Mannings n-value is in the range of 0.009 to 0.015 depending on the smoothness of the liners. With the smooth...
Combined Load Testing of Prestressed Concrete Cylinder Pipe
A series of combined load tests were run on prestressed concrete cylinder pipe in order to evaluate a proposed new method of design for pipe made to AWWA Standard C301. These tests involved...
