3. Earthquake Deformation/Disintegration Mechanism of Masonry Walls | |||||||||||||||||||||||||
Since the Hyogoken-Nambu Earthquake in 1995, a range of earthquake-proofing measures has been promoted for a host of structures on the assumption of a future large-scale earthquake. However, it is not yet possible to evaluate the stability of railway masonry walls because their behavior under earthquake conditions is unclear. The Railway Technical Research Institute (RTRI) therefore conducted a shaking table experiment using a model masonry wall to clarify its mechanism of disintegration from seismic forces. |
