摘要
Abstract
Two issues are occasionally involved in the "damage identification"-based safety assessment method for structures suffered from explosion,i.e.,modeling of damage identification and uncertainty of materials that induced explosion.Integrated solutions for the two issues were proposed in this study and applied to a transformer substation subjected to blast loading with satisfactory accuracy.For the first issue,the damage phenomenon of structures could be modeled in a mathematical manner by means of numerical and experimental methods.A flow path in the form of " damage identification-information extraction-modeling" was also suggested.For the second issue,the reasonable value ranges for the ascending and descending times of explosive loads-time curves could be determined based on the type and characteristic of the explosive source,following a parameter sensitivity analysis.The study results had a general meaning for the " damage identification"-based safety assessment method.关键词
