Probabilistic Response Simulation and Regional Vulnerability Determination Using Response Surface Metamodels
نویسندگان
چکیده
This research presents an alternative means of calculating vulnerability relations for buildings. Simulation-based fragility curves generated using a Monte Carlo simulation are usually not practical because of the large number of time-consuming analyses needed to obtain reliable statistics of the outcomes. This research implements a response surface metamodel to approximate complex analysis in a function-like manner. Monte Carlo simulation can then be efficiently performed using the metamodel to calculate fragility. The methodology is implemented in the rapid seismic fragility assessment of a hypothesized building portfolio. Resulting vulnerability relations for each building in the portfolio are presented.

متن کاملValidation of regression metamodels in simulation: Bootstrap approach
Simulation experiments are often analyzed through a linear regression model of their input/output data. Such an analysis yields a metamodel or response surface for the underlying simulation model. This metamodel can be validated through various statistics; this article studies (1) the coefficient of determination (R-square) for generalized least squares, and (2) a lack-of-fit F-statistic origin...

متن کامل The Quantification of Uncertainties in Production Prediction Using Integrated Statistical and Neural Network Approaches: An Iranian Gas Field Case Study
Uncertainty in production prediction has been subject to numerous investigations. Geological and reservoir engineering data comprise a huge number of data entries to the simulation models. Thus, uncertainty of these data can largely affect the reliability of the simulation model. Due to these reasons, it is worthy to present the desired quantity with a probability distribution instead of a sing...
