Use of Experimental Datat to Develop a Joint Deformation Model for use in Push-Over Analyses of RC Frame Structures

9812464鬼魂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。其中一组挑战涉及更彻底地了解单个构件和结构的非弹性力-变形关系，以及根据位移而不是力做出设计决定的必要性。第二组挑战涉及为“性能状态”制定明确的定义，以及确定在这些状态下预计会出现什么类型的结构和非结构损害。该项目旨在组织现有信息和开发新的实验信息，以便将基于性能的设计程序应用于钢筋混凝土抗弯框架结构。特别是，本研究将集中于梁柱连接的非弹性行为及其对钢筋混凝土框架结构侧向力-侧移关系的影响。关于钢筋混凝土梁柱节点的弹塑性性能已有大量的数据，但这些信息必须重新组织，才能应用于基于性能的设计过程中的基本分析技术-“Push-over”分析。此外，还将开发关于特定非标准梁柱节点配置的附加信息。这是CMS-INT计划NSF 98-36“美日城市地震减灾合作研究”第一轮(FY‘98)竞赛的奖项。***

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". ***
