CAREER: Modular Nodes for Joints in Steel Special Moment- Resisting Frames

PI建议创建结构配置，消除关键部分的现场焊接，从而允许其他更具延展性的区域作为结构的容量限制。这种设计方法很难用今天典型的轧制结构和连接程序来完成。因此，研究的关键在于开发和实现一个特殊配置的模块化节点。设想了一种专门设计用来减轻焊接应力的铸钢结构。模块化节点实施的副产品是易于安装，面板区域的微调能力，以及促进被动结构控制。提出的研究目标是提供改进的面板区域响应和更可靠的延性在抗弯矩框架的节点。

PI proposes creating structural configurations that eliminate the field weld from the critical sections, thus allowing other more ductile areas to serve as capacity limits for the structure. This design approach is difficult to accomplish using the typical rolled configurations and connecting procedures of today. Therefore, the research hinges on the development and implementation of a specially configured modular node. A cast steel configuration specifically designed to mitigate the weld stresses is envisioned. A by-product of the modular node implementation is ease of erection, fine tuning capabilities at the panel zone, and the facilitation of passive structural control. The objective of the proposed research is to provide improved panel zone response and more reliable ductility within joints of moment resistant frames.
