AIJ guideline against accidental actions is published as a book, "Introduction to shock-resistant design of buildings". This contains respect to objective and scope, design loads, member design, design criteria, non-structural element, progressive collapse and design examples. The objective of AIJ guideline is to minimize human and property damage in building structures against accidental actions based on the performance-based design. Target buildings for design are offices, apartments, hotels, hospitals, schools and public buildings. Structural systems of the buildings are limited to reinforced concrete and steel frame structures. In this paper, the overview of the AIJ guideline is introduced.

An important aspect in designing nuclear facilities is their safety, which is ensured by reducing the probability of radiation leakage, including that due to physical impact. We determined the factors necessary for testing the impact resistance of steel frame members of the facilities. Little research has been conducted on the impact resistance properties of steel frame members. After the Hyogo-ken Nanbu Earthquake, the relationship between strain rate and impact resistance properties has been studied. First, we classified destruction modes with regard to the limit state of the steel frame member against the impact force and provided an example of considering the impact velocity as an index of the required performance. Next, we reported about the studies of the strain rate dependence of materials and high-speed loading experiments on the steel member. Finally, we showed the formulated equations for finding the crack/penetration in the steel structure due to the impact force.
