This research program continues work in a second phase evaluation of the performance and safety of buildings designed according to the recent provisions recommended by the Uniform Building Code (UBC) and the Structural Engineering Association of California (SEAOC). Research will concentrate on sensitivity of risk to uncertainty in structural resistance, in particular the contribution of nonstructural components; appraisal of current code procedures; and development of alternative procedures for more risk consistent design. Additional building types, i.e., eccentric braced frame and dual frame systems, will be studied. Based on the results of the risk study, the Rw factors for different building types will be carefully examined and if needed alternative values of Rw will be commended which are more consistent with safety required for different building types. Also, design procedures will be developed which provide a given amount of damage control through drift limitation. Knowledge to be gained in the seismic behavior or representative building types, cladding, and nonstructural elements to be studied will be most positive. Results are anticipated to have an important impact on building code development.

这项研究计划继续在一个 第二阶段业绩评价 和安全的建筑物设计， 委员会最近建议的规定， 统一建筑规范（UBC） 美国结构工程协会 加州（SEAOC）。 研究将集中在敏感性 结构阻力的不确定性风险， 特别是 非结构部件的鉴定 现行守则程序; 更多风险的替代程序 一致的设计。 更多建筑 类型，即，偏心支撑框架和双 系统，将进行研究。 基于 根据风险研究结果， 不同的建筑类型将被仔细地 检查，如果需要， Rw将受到赞扬， 符合不同的安全要求 建筑类型 此外，设计程序将 提供一定数量的 通过漂移限制进行损害控制。 在地震中要获得的知识 行为或代表性建筑类型， 包层和非结构元件， 研究将是最积极的。 结果 预计将对 建筑规范发展。
