Development of Reliability-Based Integrated Design-Construction Quality Assurance System of Penstock
A more rational design-construction quality assurance system is proposed by applying the concepts of the reliability-based design methods. By applying this system, the design level of...

Limit States Reliability Interaction in Optimum Design of Structural Systems
A multiobjective optimization approach to deal with structural reliability-based design under multiple limit states is developed. This approach resolves the limit states reliability interaction...

Structural Optimization Based on Component-Level Reliabilities
A minimum-weight optimum design procedure is proposed including the reliabilities of various elements in a structure as constraints. The reliability indices corresponding to the various...

Optimum Studies of Coefficient Variation of UBC Seismic Forces
This paper presents an optimization algorithm for finding optimal parameters of a nondeterministic structure subjected to UBC seismic load for both normal and lognormal distribution models....

Evaluation of Lifetime Risk of Structures?Recent Advances of Structural Reliability in Japan
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,...

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...

Background Studies for the Determination of Strength Functions in Eurocode 3?Design Rules for Steel-Structures
At present common unified rules for the design of Civil engineering structures are being prepared on the initiative of the Commission of the European Communities. Eurcode 3, which gives...

Reliability of Steel Columns Subjected to Buckling?Comparison of International Standard Codes of Design
Standard codes of design represent the phenomenon of buckling by means of a curve taking into account random structural imperfections. The author suggests a probabilistic method to evaluate...

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...

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...

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 of Miter Gates
A new approach for the reliability calculation of miter gates is presented. The reliability and hazard functions are related to the surficial wear of miter gates on their horizontal sill....

Secure Landfills: Reliability-Based Analysis and Design
A framework is outlined for reliability-based analysis and design of secure landfills. Reliability, R, is the estimated probability landfill leakage, Ql, is below an allowable limit, Qf;...

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....
