Fuzzy Random Dynamical Reliability Analysis of Aseismic Structures
In our previous papers, by taking account of the fuzziness in the earthquake excitation, a fuzzy random model of earthquake ground motion has been established and a method of fuzzy random...
The N-Year Maximum Mean Values and the Coefficients of Variation of Loads Subjected to Port and Offshore Structures
It is necessary to know mean values and coefficients of variation of loads in order to verify the safety of structures. In this paper, the N-year maximum mean values and the coefficients...
Nonlinear Load Exceedances with Correlated Sustained Load Process
Past studies on nonlinear structural response of a single member only concerned with independent, identically distributed load magnitudes. When the structural member is subjected to cumulative...
The Extremes of Combinations of Environmental Loads
The objectives and the general approach of an offshore environmental data and extremal analysis are described. The intention is to develop long-term design values of wave, wind and current...
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...
Reliability-Based Analysis of Shallow Foundations
The effects of different parameters on the reliability of shallow foundations are examined. It is found that the footing depth, the footing length, and the load ratio have almost no effect...
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...
Downtown in Soft Ground
Critchfield and MacDonald describe the shield excavation of twin bus tunnels 21.25 ft in diameter and 5,000 ft long as part of the Downtown Seattle Transit Project. This $450 million project,...
Earth Pressure Acting on Buried Flexible Pipes in Centrifuged Models
Distributions of both normal and tangential earth pressures acting on three flexible model pipes having different wall thicknesses were successfully measured in centrifuge model tests....
Safety Assessment of Welded Pipelines Undergoing Large Ground Deformation
