Some design examples are presented to evaluate the shock-resistant performance of target buildings to confirm the applicability of the design criteria of AIJ guideline. Dynamic analyses are performed using SDOF model of an individual member on which an impulsive load is acting. Furthermore, analyses are performed using finite element model for the same member, and the results are compared to the results of the corresponding SDOF model for validation. Frame building structure model which is supposed to be located at the corner of a crossroad is investigated as an example. Dynamic responses and the corresponding damage states are illustrated for this building subjected to shock loads due to road vehicle crashes. As a non-structure member case, examples of window glass destruction subjected to internal and external gas explosions are presented.

Though design guidelines for earthquake and wind loads are specified for buildings, the guideline for impulsive load as explosion and impact is not specified yet in architectural field. This document corresponds to Chapter 8 of the book titled "Introduction to Shock-Resistant Design of Buildings" which made towards the impact design guideline. Some design examples are presented to illustrate the applicability of the tentative guideline for impulsive loads. Two buildings - a steel frame and a reinforced concrete frame building structures - located at the corner of a crossroads are selected. Dynamic responses and the corresponding damage states are illustrated for the cases of two buildings subjected to impact loads due to road vehicle crashes, internal and external explosions. The idea has been shown in this document are those that can be applied to nuclear facilities.

Some design examples are presented to illustrate the applicability of the tentative AIJ guideline to a selection of buildings. Two buildings, a reinforced concrete and a steel frame building structure, located at the corner of a crossroads were selected. Two accident scenarios are considered: road vehicle crashes caused by automobiles and dump trucks and internal gas explosion. Application examples of road vehicle crashes at the first floor of the selected buildings and internal gas explosion are shown in this paper. As an example of non-structural member, this study also presents information on glass velocity and dispersion when loaded by an internal gas explosion.

Though design guidelines for earthquake and wind loads are specified for buildings including a nuclear facility, the guideline for impulsive load as explosion and impact is not specified. Some design examples are presented to illustrate the applicability of the tentative guideline for impulsive loads. Two buildings -a steel frame and a reinforced concrete frame building structures- located at the corner of a crossroads are selected. Both buildings are designed to resist major earthquake loads, as specified by the AIJ seismic design codes. Dynamic responses and the corresponding damage states are illustrated for the cases of two buildings subjected to impact loads due to road vehicle crashes at the first floor of the buildings. Moreover, dynamic responses are illustrated for the cases of the frame buildings subjected to internal and external explosions. This study provides information on dispersion of window glasses of building structures as an example of non-structural member.
