Lifetime-Maximum Load Effect for Highway Bridges Based on Stochastic Combination of Typical Traffic Loadings
An efficient and accurate method is proposed for probabilistic assessment of lifetime maximum load effect on highway bridges caused by traffic load. Probability distribution of the lifetime...
Some Considerations on the Acceptable Probability of Failure
The acceptable failure probability of technical structures and systems is studied in this paper. The problem is approached from two points of view: the personal and the social point of...
Safety Plans for Buildings, Structures and Technical Facilities
Safety is an important quality feature and depends on all activities within the building process. The safety concept must therefore consider all phases of the building process, from the...
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...
General European Principles of Codes Concerning Reliability
The requirements for reliability cover safety, serviceability and durability and consider different causes and types of failure. They may concern the occurrence of a failure or the duration...
On the CICIND Code
The CICIND Model Code for Concrete Chimneys was created by CICIND, an international technical association which has as one of its main aims the creation of harmonized internationally accepted...
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...
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...
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...
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 Models of the Mohr Failure Criterion for Mass Concrete
Failure in biaxially stressed concrete is here modelled by the Mohr criterion. The reliability of a stress state is evaluated in terms of 2 load variables and 1 or 2 strength variables....
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....
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...
Reliability-Oriented Materials Design of Composite Materials
A basic formulation for evaluating safety index of unidirectional fiber reinforced laminate is presented. The proposed formulation is based on in-plane failure criteria of composite laminate...
Strategies for Bridge Inspection Using Probabilistic Models
This paper describes the application of probability analyses in planning an inspection program for highway bridges. When damage in the form of fracture and cracking is the major concern,...
Analysis of Bridge Maintenance and Rating Procedures
In the United States, bridges are routinely rated to evaluate their existing conditions. The formula used to evaluate bridges is called the Sufficiency Rating Formula. The formula uses...
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...
Development of a Safety Assessment System for Steel Bridge Erection Work
In order to secure safe execution of steel bridge erection work, development of a comprehensive checking system to set up safety countermeasures at the stage of construction planning prior...
