内填混凝土双钢板短肢组合剪力墙滞回性能研究

Research on hysteretic behavior of short-lamb couple-steel-plates shear-wall

内填混凝土双钢板短肢组合剪力墙结构是一种新型的抗侧力体系,应用ABAQUS有限元软件分析了短肢剪力墙肢厚比、高跨比及钢板厚度变化对其滞回性能的影响。分析结果表明:剪力墙的高跨比变化对结构的滞回性能影响很大,高跨比的增大降低了结构承载能力和耗能能力,提高了结构的延性;混凝土厚度引起的肢厚比变化对滞回性能基本无影响,肢长引起的肢厚比变化影响较小;钢板厚度的增加在一定程度上可提高结构的滞回性能。

The short-lamb couple-steel-plates shear-wall structure is a new type of lateral-force resisting sys-tem. Based on the ABAQUS finite element model, this paper studied the influence of the span-thickness ratio（STR） of short-lamb shear-wall and the depth-span ratio（DSR） on the hysteretic behavior. The results showed that the change of the depth-span ratio had great interaction to the behavior of structures, the increase of the depth-span ratio decreased the bearing and energy consuming of the structure, and the ductility of the structure was improved; and the varied ratio of thickness caused by the varied thickness of the concrete showed no inter-action to the hysteretic behavior, and the varied ratio of thickness under the high depth-span ratio presented lit-tle interaction to the structure. The increase of the thickness of steel-plate improved the hysteretic behavior of the structure in some degree.
