| 中文摘要: |
| 钢板深梁作为一种新型的耗能构件，可以实现钢框架内填钢板深梁结构刚度宽范围渐变调幅。通过对钢板深梁跨高比分别为2 和 0.75的钢框架内填钢板深梁结构进行低周反复荷载实验，得到了该结构滞回曲线和骨架曲线。采用“通用屈服弯矩法”简化的双折线恢复力曲线对钢框架内填钢板深梁结构进行动力时程分析来得到结构的能量时程曲线。研究结果表明:钢框架内填钢板深梁结构抗震性能良好，双折线恢复力曲线用于结构动力时程分析，为研究结构损伤设计和能量设计提供基础。 |

| As a new energy component , the steel plate deep beam filled in the steel frame may realize the modulation of structural stiffness in a certain range. By cyclic loading model test on two steel plate deep beams filled in the steel frame with span height ratios of 0.75 and 2 respectively, the hysteretic loops and skeleton curves are obtained.The bilinear restoring force model is used for time history analysis to get time history curve of energy. The result indicates that seismic performance of the steel plate deep beam filled in the steel frame is better, and structural dynamic analysis making use of bilinear restoring force model provides the basis for structural damage design and energy design. |
