Reliability-Based LRFD For Bridges: Theoretical Basis
This paper develops a theoretical basis for obtaining probability-based load combination criteria for structural design. For choosing the load combinations and for determining the factors...

Probabilistic Evaluation of Load Factors for Steel Rigid-Frame Piers on Urban Expressway Network
A procedure is proposed for calculating the optimal load factors for steel rigid-frame piers using the extended level 2 reliability method. Twelve typical types of pier structures are...

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...

Code-Implied Structural Safety for Earthquake Loading
A method is described for calculating the probability of failure of reinforced concrete frame structures due to earthquake loading, for use in code calibration exercises. The failure criterion...

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...

Probabilistic Basis for Bridge Design Codes
There is a growing interest in the development of rational design criteria for bridges. The fundamental problem is evalution of the loads and load carrying capacity. However, load and...

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
This paper reviews some aspects of limit states design for masonry structures based primarily on experience with a new Canadian code. Steps in an advanced second order safety index analysis...

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...

Reliability Analysis of Axially Compressive Members
In the steel structure design code (TJ17-74) in China, a single curve was adopted for designing axially compressive members and the reliability of the column analyzed previously was based...

Reliability Synthesis of CFRP Laminated Plate
The paper presents a formulation of shift synthesis to improve the reliability of fiber reinforced plastic (FRP) laminated plates with uncertain elastic constants and lamina strength....

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...

Study on Reliability of Actual Steel Structure Using Measured Data
The measurement of uncertainties was taken on an actually constructed steel structure. The stress and strain of each part of the structure are calculated based on the conditions assumed...

Damage Assessment Based on Repairability Criterion
This paper discusses the assessment of damage of protective structures based on the repairability criterion. The variables of the repairability are the amount of repair, repair cost, repair...

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...

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-Based Bridge Life Assessment
Fatigue considerations have usually entered design codes as a secondary consideration and often under the guise of serviceability limits. Most engineers felt if the maximum stress ranges...

Effect of the Uncertainty About the Fatigue Limit on Highway Bridge Reliability
Current fatigue design specifications for welded steel highway bridges subjected to high traffic volumes require the design to be capable of resisting high-cycle, long life conditions...

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...
