A Structure Economic Loss Optimization Method with the Uncertainty of Ground Motion Amplitude for Chinese Masonry Building

In the catastrophe insurance industry, it is impractical for a model to simulate millions of sites’ environments in short time. Hence, attenuation relation often adopted ground motion on account calculation speed, and both expectations uncertainties must be calculated. Due vulnerability curves our being based simulations with large number deterministic motions, necessary but not efficient loss assessment analyze all possible amplitudes their corresponding rates. This paper develops simplified method rapidly uncertainties. this research, Chinese masonry buildings are focus. The result shows that modified gives accurate results quickly.
