This work aims at developing a fundamental methodology for the qualitative reliability design of machines and structures to cope with the present situation of small production with a wide...
Fuzzy Random Dynamical Reliability Analysis of Aseismic Structures
In our previous papers, by taking account of the fuzziness in the earthquake excitation, a fuzzy random model of earthquake ground motion has been established and a method of fuzzy random...
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...
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...
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...
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...
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....
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...
