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...
Extraordinary Live Load Model in Retail Premises
Based on a live load survey on six supermarkets, the probabilistic nature of sustained live loads and simulated extraordinary live loads were examined. The simulation was performed to...
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...
Extreme Value Distribution for Stochastic Processes Subject to a Full Load Climate
Reliability analysis of structures subject to environmental loads generally involves load effects which are properly treated as stochastic processes, and requires determination of the...
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...
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...
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...
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,...
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....
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...
