Load Modelling for Single Story Steel Buildings
Realistic load assumptions for single story buildings are thus far complicated by the insufficient state of the modelling of individual loads as random variables or stochastic processes...
Structural Reliability of Wood Beam-Columns
A formulation for reliability-based design procedures of wood columns and beam columns is presented. The load carrying capacity of these structural members is obtained using a non-linear...
Ultimate Limit State Design for Earthquake Resistant Steel Frames
This paper describes a basic methodology to assess the reliability of steel framed structures subjected to ultimate earthquakes. After a discussion on past damage criteria, a modified...
Damage Assessment of Bridge Structures by System Identification
A method for the damage estimation of bridge structures under seismic ground excitation is developed based on system identification approach. The dynamic behavior of a damaged structure...
Seismic Reliability Analysis for Elevated Pressure Vessels
This paper presents two approaches for assessing the seismic reliability of elevated pressure vessels. A discretized mass mechanical system is used to model the dynamic effects of liquid...
Probability Based Bridge Safety Analysis
Traditional methods of quantifying safety of highway bridges have been associated with deterministic analysis. However, ascertaining the true measure of safety, or reliability, should...
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...
Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...
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,...
Vibration Tests and Damage Detection of P/C Bridges
A three-span countryside P/C bridge has been found to have excessive deflections in two of the three spans. It is reported that the prestresses in tendons of two girders of different spans...
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...
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...
Advances in Pipeline Materials and Design in Europe and North America
This paper presents an overview of various developments in materials technology and design procedures in the Western Hemisphere over the last 20 years. Some projections for anticipated...
Ambiguities and Inanations of Current Plastic Pipe Specifications
This paper discusses current specifications, including materials for plastic pipe as compared to other pipe specifications, including rigid pipe materials. It discusses the ambiguities...
FE Elastic Analysis of Measured Earth Pressure on Buried Rigid Pipes in Centrifuged Models
FE elastic analyses of earth pressure on buried rigid pipes yielded results that agreed well with the earth pressure measured in 42 centrifuged models, confirming both the reliability...
Museum Showcases the Future
On May 4 in Philadelphia, the Franklin Institute's new wing, called the Futures Center, will open to the public. When the institute's neoclassic main buiding...
Outline of Performance Assessment Study on Geological Isolation System in Japan
The goals of current R&D activities are to ensure the feasibility of geological isolation of HLW in Japan and then to establish the social acceptance. In order to attain these...
A Gas-Flow Source Term from a Nuclear Waste Container in an Unsaturated Medium
The potential nuclear waste repository at Yucca Mountain is to be in partially saturated rock. Released radioactive gases would have a direct pathway to the biosphere. The entry of air...
