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

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。其中一组挑战涉及对单个构件和结构的非弹性力-变形关系的更彻底的理解，以及根据位移而不是力做出设计决策的需要。第二组挑战涉及对“性能状态”的明确定义，以及确定在这些状态下预期的结构和非结构损坏类型。本项目旨在组织现有信息并开发新的实验信息，以便将基于性能的设计程序应用于钢筋混凝土（RC）抗弯矩框架结构。特别是，本研究将集中在梁-柱连接的非弹性行为及其对RC框架结构的侧向力与侧向位移关系的影响。钢筋混凝土梁柱连接的非弹性性能有大量的数据，但这些数据必须经过整理才能应用于“推倒”分析，而“推倒”分析是基于性能的设计过程中的基本分析技术。此外，对于特殊的非标准梁柱节点配置的附加信息将被开发。这是CMS-INT计划NSF 98-36“美日城市地震减灾合作研究”第一轮（1998财年）竞赛下的一个奖项。＊＊＊

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". ***
