The objective of this Workshop on Earthquake Site Response and Seismic Code Provisions, November 18-20, 1992, University of Southern California, concerns the effects of site response on earthquake ground motions; the aim is to develop recommendations for modifications to existing design guidelines and codes for earthquake site response. It follows on from the Site Effects Workshop held at the University of New York at Buffalo in 1991. Financial support for this workshop is provided by the National Science Foundation, the National Center for Earthquake Engineering Research (NCEER), the U.S. Geological Survey (USGS) and the Southern California Earthquake Center (SCEC). The need to examine the soil categories and site factors (S factors) used in building code site response provisions arises from: (a) concerns with the existing definitions of site factors, and (b) the fact that current building code provisions (that is, soil factors S1 through S3) were developed in the mid-1970's (S4 was added following the 1985 Mexico earthquake). The need for this workshop is further highlighted by the accumulation in recent years of extensive research data and new knowledge on site response effects. It is strongly supported by committees involved in: (a) the planned 1994 revision of the NEHRP (National Earthquake Hazard Reduction Program) Recommended Provisions for The Development of Seismic Regulations for New Buildings; and (b) by the Structural Engineers Association of California's (SEAOC) 1993 planned revision of the "Blue Book". The results from this workshop will provide essential input and recommendations to these committees' activities. The workshop involves geotechnical engineers, seismologists and structural engineers. It is planned to publish the workshop proceedings in March 1993.

1992年11月18-20日在南加州大学举行的关于地震场地反应和地震规范规定的研讨会的目的是关于场地反应对地震地面运动的影响；其目的是为修改现有的地震场地反应设计准则和规范提出建议。它是1991年在纽约大学布法罗分校举办的场地效果研讨会的后续活动。这次研讨会的资金由国家科学基金会、国家地震工程研究中心、美国地质调查局(USGS)和南加州地震中心(SCEC)。审查建筑规范场地反应规定中使用的土壤类别和场地因素(S因素)的必要性源于：(A)对场地因素的现有定义的关注，以及(B)当前建筑规范规定(即，土壤因子S1至S3)是在20世纪70年代中期发展起来的，S(S4是在1985年墨西哥地震后增加的)。近年来积累了大量的研究数据和关于现场反应影响的新知识，进一步突出了举办这一讲习班的必要性。它得到了参与以下工作的委员会的大力支持：(A)计划于1994年修订NEHRP(国家减少地震危险方案)关于制定新建筑物地震法规的建议规定；以及(B)加州结构工程师协会(SEAOC)计划于1993年修订《蓝皮书》。这次研讨会的结果将为这些委员会的活动提供必要的投入和建议。研讨会有岩土工程师、地震学家和结构工程师参加。计划在1993年3月出版讲习班会议记录。
