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.

Accidental actions on building structures involve impact and explosion loads. The design loads due to impact are determined by experiment data, impact simulation and energetics approach. These loads are presented in the form of load-time (F-t) curves caused by collision and explosion. It is assumed that the structure is rigid and immovable and that impacting body absorbs all the energy (i.e., hard impact condition is supposed), because this assumption gives conservative results in general. Responses of individual structural members directly-subjected to an impulsive load are evaluated. These responses are classified into three types; impulsive response, dynamic response, and quasi-static response. The maximum responses are basically estimated by direct integration method with a single-degree-of-freedom (SDOF) model. The procedure of the SDOF modelling based on the classification of types of members and failure modes is proposed in AIJ guideline.
