ABSTRACT
The purposes of this research emphasize on the behavior of
explosion demolition structures, and try to find a simple model
to explain the failure behavior of explosion
demolition structure. The failure behavior discussed includes
collapse-direction, collapse-range and collapse-altitude.
Research works are divided into two parts. One is
theoretical analysis and the other is experiments. The
contents includes collapse-direction of single-story single-
bay buildings, collapse-range of single-story single-bay
buildings, collapse-height of single-story single-bay
buildings, reasonable explosion gap, the weight needed to
collapse completely, and potential energy needed to
collapse. Experiments are carried out for possible failure
forms of single-story single-bay buildings and the bearing
weight ability of explosion demolition of single-story
single-bay buildings. The first part of the experiments is to
discuss the problems may be met in all kinds of failure
forms. The second part of the experiments is to discuss the
weight of the structure needed to have a complete collapse.
