FINITE ELEMENT ANALYSIS OF AXIAL COMPRESSION PROPERTIES OF PREFABRICATED SRCT SHEAR WALL STRUCTURES
-
摘要: 为研究装配式钢-混凝土组合管(SRCT)剪力墙的轴压受力性能,完成了11个SRCT剪力墙试件和1个钢筋混凝土(RC)剪力墙试件的数值模拟分析,研究距厚比、钢材强度与穿筋截面对构件轴压性能的影响。分析结果表明:所采用的数值分析方法能较好反映SRCT剪力墙的轴压受力性能,与RC剪力墙相比,SRCT剪力墙具有较高的轴压承载能力与轴向刚度;在受力过程中,SRCT剪力墙混凝土压溃现象先于钢板屈服;合理的穿筋布置可使穿筋在试件受力与破坏过程中始终处于弹性。

Abstract: In order to study the axial compression performance of prefabricated SRCT shear wall, 11 prefabricated SRCT shear walls and one reinforced concrete shear wall were tested under analysis of numerical simulation. The influences of distance-thickness ratio, steel strength and section of tie-rebar on the axial compression properties of the specimens were analyzed. The analysis results showed that the results of the finite element model could reflect the axial compression properties of SRCT shear wall. Compared with RC shear wall, SRCT shear wall had better bearing capacity and axial stiffness. In the process of stress, crushing of concrete in SRCT shear wall was earlier than yield of steel plate. Reasonable design could remain the tie-rebar in the elastic stage during the loading process. -
