Based on results of seismic hazard analysis for a considered site, seismic reliability of a strengthened RC single-story industrial building against collapse has been evaluated. Inelastic...

Safety Assessment Methodology for Construction Operations
There are many factors that affect the safety of construction operations which might lead to failures and accidents. The factors are associated with random, human-based or system uncertainty....

Assessment of Safety of Existing Buildings Using Fuzzy Set Theory
In this paper, an approach to estimate structural safety which may serve as a bridge between the theoretical and empirical approaches is explored. The new method combines subjective judgment...

Risk Assessment of Utility Network Systems Using Expert Opinions
This paper describes the application of an expert opinion and survey approach to the problem identification and risk assessment of engineering systems. The method of expert opinion for...

Structural Error Identification for Control of Construction Accuracy
In cases of large-scaled structures it is very important to keep the criteria of construction accuracy and therefore to correct construction errors if any considerable errors are found...

Some Insight in Autoregressive (AR) Spectral Modeling
The difficulties associated with the determination of reliable autoregressive (AR) approximations of the Pierson-Moskowitz and Davenport spectra are examined from the standpoint of developing...

Continuous Simulation of Gaussian Processes with Given Spectrum
A new algorithm, to be called MIMA (modulated interpolated moving average) allows stationary Gaussian processes with given spectral density to be simulated in continuous time, while providing...

Open World Problems in Structural Reliability
A closed world model represents total knowledge about everything in a particular system. An open world model represents partial knowledge where some things are known to be true, some are...
