报告内容简介：

Topic 1: Static and dynamic behavior of stone arch bridge models

I. Compression and shear tests for adjacent two stones to get the material property

II. Static strength and behavior of miniature stone arch models/arch models with stone wall

III. Vibration characteristics of miniature stone arch models subjected to a sine wave and seismic wave.

IV. Static and dynamic test of a real stone arch bridge using a 20-ton dump truck

Topic 2: Damage of stone bridges by Kumamoto Earthquake and Collapse behavior of stone wall by model test

Damage to the stone bridge that collapsed for the first time by the Kumamoto earthquake that occurred on April 14, 2016, was reported. Therefore, it is necessary to elucidate the cause of the damage of the stone bridge caused by the earthquake and to examine the structure of the stone bridge resistant to the earthquake.  We introduce the damage of stone bridges by the Kumamoto Earthquake. Next, in order to clarify the collapse mechanism of spandrel walls for the stone bridge caused by the earthquake, a sinusoidal wave was excited on miniature stone bridge models on the shaking table.
