9403612 Wight The main objective of this project is to develop a design strategy for the use of ductile steel bracing fro the seismic upgrading of slab-column frame structures that are located in moderate and high seismic zones. To develop the design approach, the experimental data obtained from the tests on a large scale two-story by two-bay reinforced concrete slab-column framed and from the test or slab-column connection assemblies and columns jacketed with steel angles and plates will be analyzed and synthesized. The design strategy will utilize the strength and stiffness contributions from the unbraced portions of the existing slab-column structure. The results will be presented in a form that can be understood and used by practicing engineers. ***

9403612 Wight本项目的主要目标是开发一种设计策略，用于位于中高地震带的板柱框架结构的抗震升级。 为了发展设计方法，将分析和综合从大型两层两跨钢筋混凝土板柱框架的试验以及从试验或板柱连接组件和柱与角钢和钢板的试验获得的试验数据。 设计策略将利用现有板柱结构的无支撑部分的强度和刚度贡献。 结果将以实践工程师可以理解和使用的形式呈现。 ***
