Earthquake‐induced ground motions are determined by a combination of source, path, and site effects. As seismic waves propagate along a path from the fault rupture to a given site, they often encounter softer geologic materials as they approach the ground surface. Site response, broadly defined as the effects of near‐surface geologic materials on seismic waves, can significantly alter the amplitude, duration, and frequency content of ground motions. Therefore, to properly estimate seismic hazards and design earthquake‐resistant infrastructure, it is necessary to accurately assess the effects of site response on ground motions.Observations of large variations in damage patterns over short...

场地响应估计进展专题介绍

地震引起的地面运动是由震源、路径和场地效应共同决定的。当地震波沿着从断层破裂到给定地点的路径传播时，它们在接近地表时经常遇到较软的地质材料。场地响应，广义上定义为近地表地质材料对地震波的影响，可以显着改变地震动的幅度、持续时间和频率成分。因此，为了正确估计地震灾害和设计抗震基础设施，有必要准确评估场地响应对地震动的影响。在短时间内观察破坏模式的大变化...
