In this paper, a method to semi-automatically construct an analysis model from point clouds of steel truss bridges is proposed. The authors proposed practical analysis models of truss bridges based on structural experiment and reproduction analysis of end sway bracing. For efficient seismic reinforcements enormous existing bridges, it is necessary to construct analysis models efficiently. Therefore, point clouds that represented 3D features of targets are used to construct analysis models without using drawings. The proposed method is applied to point clouds of end sway bracing in a truss bridge and verified its accuracy based on structural experiments and reproduction analysis.

We proposed to take several wave boundaries which make possible multi-way incident into three dimensional analytical boundary and then we made three dimensional tsunami analysis over wide area based on the result of two dimensional analysis. By this proposed technique, the propagation movement of two dimensional tsunami was reflected in three dimensional analysis boundary, and the continuous generation of the tsunami simulation that comprised a macroscopic evaluation of the tsunami and a microscopic evaluation in the vicinity of the site could be shown. This analysis of the continuous generation of tsunami can be expected as a technique to be able to achieve the flood simulation in high accuracy as well as being able to make the evaluation of the power of tsunami load that affects on embankments, bridges, and buildings.
