In order to provide safe and comfortable infra-structures, a performance evaluation against impact (high speed) loadings and a deterioration diagnosis of existing concrete structures has been developing in our laboratory. Several kinds of computer simulation based on the solid mechanics and structural engineering has been utilized to perform our research. In the fundamental research of a performance evaluation against impact loading, new simulators, including particle simulation, incorporated with damage mechanics and fluid mechanics has been developed. The goal is to design the Rock-Shed, derailment barrier of bullet train (Shinkansen) and flood-tide barrier. In addition, for the research of a deterioration diagnosis, a new hybrid nondestructive testing with hammering and infrared thermography is developing to expand the applicability and to increase the accuracy of the diagnosis of existing structures with various damage level.
