Outline of Final Research Achievements

We focus the buildings and their elements’ behaviors due to impacting-objects; for example, non-structural elements' damages as causing serious human injury or a progressive collapse over the entire buildings. However, hazardous actions of the buildings or their elements accompanying to the general impulsive accidents have not been evaluated enough quantitatively. Thus emphasis is put on making collapse behaviors of various building elements quantify through data extraction with the video motion capturing. Destructive tests using glazing specimen are executed and the impacting moment of the plate glass versus the flying object are recorded with the high-speed video camera. Scattering motions of broken glass pieces are observed quantitatively with motion extracting analyses. FEM analyses are also carried out. By comparing the simulation and the experimental results, it is assured that the FEM analysis can well-reproduce actual behavior of the breaking glass due to flying object.
