| 摘 要： | Introduction The characteristics of ground motions recorded near the fault of an earthquake are quite dif- ferent from the usual far-field ground motions. After the original recognition of their differences in the Port Hueneme earthquake in 1957, a great lot of inhabited structures and lifeline systems were damaged in the major earthquakes happened in the following years. The damages were beyond minds of seismologists and engineers. A quite rational reason is the lack of enough knowledge of t…

| Abstract: | In the last twenty years, near-field problems became an important topic for both seismologists and civil engineers. The one aspect is to illuminate mechanisms of earthquakes and explain new phenomena. The another aspect is the ground motions, which are usually assigned by engineers as a type of input load for seismic design of structures, sometimes can control the final design results. The experiments, performance evaluations and other related aspects are all based on the specified type of load. As a result, many aspects related to civil engineering will be influenced by changes of the type of load. Hence, the characteristics of the load and the corresponding response of structures are desired for studying. In this paper, the state-of-the-art of near-field problems in civil engineering is comprehen- sively reviewed, which include inherent characteristics of near-field ground motions and influences of these ground motions on civil structures. The existing problems are pointed out and work needed to be further investi- gated in the future is suggested. It is believed that the information in this paper can be useful to advance the state of investigation on near-field problems. |
