In this study, in order to establish a simple and engineered analysis method for appropriately evaluating the dynamic response characteristics of steel beams under impact loading, impact response analysis method based on a fiber element approach was proposed. An applicability of the method was discussed comparing with the experimental results of a total of nine small-scale H-shaped steel beams having different span length and impact velocities of impact striker. From this study, the following results were obtained: 1) applying the proposed method, the deflection behavior of the beams can be appropriately predicted; and then 2) the method may be able to use as a tool for evaluation of the dynamic response characteristics of the H-shaped steel beams under the impact loading.

In order to rationally analyze an impact resistant behavior of the full-scale reinforced concrete (RC) girders under consecutive impact loading, it is proposed to apply an equivalent tensile fracture-energy concept for concrete elements. The applicability is investigated by conducting numerical simulations for full-scale RC girder with 8 m clear span under a 2,000 kg fallin-gweight consecutive impact loading. The numerical simulations are conducted taking an axial length of concrete elements and with/without considering the concept as the parameters, in which the reference length of concrete elements is 35.7 mm and the considered maximum length is 250 mm. From this study, it is confirmed that considering the equivalent fracture-energy concept, the model with coarse mesh can be practically applied with a proper accuracy for numerical analysis of the full-scale RC girders under consecutive impact loading.

The objective of this paper is to establish the method to explain technology for creating the reliability between people and engineer. Therefore, the view with which the risk communication model about formation of the risk perception in social psychology or reliance and the idea about new engineering accounting were united was established. The homepage about the maintenance management of the road structure in Fukushima Prefecture was made into the example, the issues on technical explanation were summarized, the contents were corrected using the method, and the effect was investigated. It is found that a new technical explanation method is useful because intelligibility increased from correction before and by having used the method.
