9812464 Wight There are several significant challenges for the structural engineer who wants to implement the performance-based design procedure. One set of challenges involves a more thorough understanding of the inelastic force-deformation relationships for individual members and structures, and the need to make design decisions in terms of displacements instead of forces. A second set of challenges involves the development of clear definitions for "performance states" and the determination of what types of structural and nonstructural damage to expect at those states. This project is aimed at the organization of existing information and the development of new experimental information for application of performance-based design procedures to reinforced concrete (RC) moment-resisting frame structures. In particular, this study will concentrate on the inelastic behavior of beam-to- column connections and their effect on the lateral force vs. lateral displacement relationship for a RC frame structure. A large amount of data exists on the inelastic behavior of RC beam- column connections, but that information must be reorganized for application to a "push-over" analysis, which is the fundamental analysis technique in the performance based design procedure. Also, additional information for particular nonstandard beam- column joint configurations will be developed. This is an award under the first round (FY'98) competition of the CMS-INT initiative NSF 98-36 "US-Japan Cooperative Research in Urban Earthquake Disaster Mitigation". ***

9812464怀特对于想要实施基于性能的设计程序的结构工程师来说，有几个重大的挑战。 一组挑战涉及对单个构件和结构的非弹性力-变形关系的更透彻的理解，以及需要根据位移而不是力来做出设计决策。 第二组挑战涉及为“性能状态”制定明确的定义，并确定在这些状态下预计会发生何种类型的结构性和非结构性损害。 该项目旨在组织现有的信息和开发新的实验信息，以应用基于性能的设计程序钢筋混凝土（RC）抗弯框架结构。 特别是，本研究将集中在梁-柱连接的非弹性行为和它们对钢筋混凝土框架结构的侧向力-侧向位移关系的影响。 关于钢筋混凝土梁柱节点的非弹性性能存在大量的数据，但是这些信息必须重新组织以应用于“push-over”分析，这是基于性能的设计过程中的基本分析技术。 此外，将开发特殊非标准梁柱节点配置的附加信息。 这是CMS-INT发起的NSF 98-36“美日城市地震灾害减轻合作研究”第一轮（FY'98）竞赛的一个奖项。 ***
