Probabilistic Models for Loads Due to Bulk Solids
This paper presents two probabilistic models for loads due to bulk solids. One model seeks to obtain an accurate presentation of the loads; the model is used as a basis for a systematic...

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...

The Task Committee on Structural Safety and Reliability of the Japan Society of Civil Engineers has made survey of recent advances in the field of structural reliability. Consequently,...

Risk Acceptance Criteria for Performance-Oriented Design Codes
A general basis for the determination of 'acceptable risks' needs to be established to facilitate the development of risk-based performance-oriented design Codes....

Modelling of Damage Due to Structural Failure
A multistage method of simulating failure situations associated with collapse of structures is described. Method is applied to evaluate statistical characteristics of the size and cost...

Probabilistic Traffic Load Models and Extreme Loads on a Bridge
This paper contains a summary of the intensive traffic measurements collected in France and Europe, and of the probabilistic distributions adopted for the main parameters. The evaluation...

Present and Future Developments in Steel Design Codes
Steel structures design codes with load and resistance factors (or 'partial factors') which are based on first-order probabilistic concepts are now in use in...

LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....

Reliability Bases for Codes for Design of Reinforced Concrete Structures
The American Concrete Institute Standard 318, Building Code Requirements for Reinforced Concrete, has permitted the design of reinforced concrete structures in accordance with limit state...

Limit States Design in Masonry

Parameter Identification and State Estimation of Structure Models in Shaking Table Test
In this paper physical parameters and inner states of structure can be estimated from the input and responses in shaking table test by means of Extended Kalman Filter (SIEKA). Comparing...

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...

A Doubling Design: Rochester's Expanding Airport
Few projects offer greater design challenges or pose more critical construction complexities than a new air passenger terminal, especially when that new terminal must be built on land...

Industrial Strength 3-D
Williams assesses the benefits of using three-dimensional computer modeling in the design of industrial structures, comparing the reality in which the computer is a useful tool for engineers...

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....

Column Separation in Pumped Pipelines
Pressure transients are common occurrences in water supply systems. Pipeline standards and design/testing techniques will normally provide sufficient protection for transmission and distribution...

Pipeline Leak Detection and Location
A real time pipeline leak detection and location system has been developed. This system consists of a numerical model for transient flow, two sets of pressure and flow measurement equipment,...

Valve Control to Avoid Column Separation in a Pipe
Maximum pressures in a pipeline can be reduced significantly by closing the valve in an optimal manner. Such an optimal valve closure policy may result in some situations in minimum pressures...

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...

The Effect of Compaction on Buried Flexible Pipes
This contribution presents an analysis of the installation of flexible pipes in granular soil. The deformation of the pipe cross section is measured in field and laboratory tests. It is...
