| 双层钢板组装式框架结构的性能研究 | |
| 摘 要： | 介绍了一种新型抗侧力结构——含薄钢板的双层钢板组装式框架结构。组装式结构建造工期短,质量好且能减少资源浪费。提出在抗侧力结构中,用钢板组装式框架结构替代原核心混凝土墙。双层钢板结构由于具有一定的后屈曲强度,因而韧性和耗能能力较好。进行了双层钢板组装式框架结构的足尺试验。结果表明:在框架结构屈服前,钢板已经屈服,故框架的破坏能得到控制。钢板提高了整个结构的初始侧向刚度,并始终处于弹性阶段,不会产生由剪切引起的局部屈曲。进行刚塑性分析,计算薄板平面内的后屈曲强度,并与试验结果进行比较。基于钢板试验数据,建立双层钢板框架结构的分析模型,并与试验结果进行比较。 |

Behavior of Framed Modular Building System with Double Skin Steel Panels |
|
| Abstract: | A new type of lateral force-resisting system,a framed modular building with double skin steel panels of slender thin steel plates is presented.Modular construction leads to faster construction,improved quality and reduced resources and waste.A steel panel strengthened framed modular system is developed for the lateral load resisting system instead of in situ concrete core walls.The proposed double skin steel panel systems showed moderate ductility and energy dissipation due to their post-buckling strength.F... |
