| Research Abstract |
Numerical analysis method for Monte-Carlo simulation of structural collapse has been developed. This method can predict the structural collapse including its variability. More precisely, through this project, the following 3 achievements have been obtained.
(1) Numerical analysis method for failure behavior, PDS-FEM has been enhanced to deal with 3 dimensional dynamic elasto-plastic problems,
(2) Computational efficiency has been enhanced by parallelization,
(3) Monte-Carlo simulation of failure behavior of structures has been performed. Besides, a dense sensor network system for synchronized acceleration measurement has been developed.
