Initial time histories of … WebJul 1, 2024 · Directivity effect will produce large acceleration amplitude and long-period velocity pulse, while the fling step will produce permanent displacement. A large part of the difficulty in studying the response of bridges to the near-fault earthquake is the lack of actual near-field records.
WebApr 4, 2024 · The velocity pulse and displacement fling-step pulse signatures may be present in a near-field earthquake ground motion record. It is generally known that near-field ground motion with pulse effects accelerated the building drift. The damage of building can also occur as a result of two or three earthquakes within the building's lifespan.
