Nonlinear Finite Element Analysis Of Shear Behavior Forwall-format Shaft Hole Wall

In recent years, with the continuous development of China ’s urbanization, more andmore high-rise buildings appear in our life, the shear wall structure is more common in thistype of building, however, in the previous earthquake we found that ordinary shear wallstructure is able to resist earthquakes, but prone to brittle failure. On the parts of the wall andthe interior wall between the windows appears more shear cracks, that affect the safety andussfullness of the structure. Therefore, we propose to use wall-format shaft hole wall structurein the multiple high-rise residential wall frame, this structural system has good energyperformance, it’s able to form a beam hinge mechanism under seismic action, and that avoidlarge shear cracks and brittle failure, protect people’s lives and property safety. Thewall-format shaft hole wall structure system has a large open hole, it’s possible to meet thepeople’s requirements of the architectural space, and avoid the pillars convex.With the promulgation and implementation of “Technical Specification for Structures ofWall-Format Shaft wall” in Hebei Province, the application of wall-format shear wallstructure has been further promotion, but this technical specification is still not perfect. Thecombined seismic shear performance of wall-format shaft hole wall structure are not includedin the specification, the main reason is that experimental research and theoretical analysis inthis area is still relatively lacking. In this article, the study of wall-format shaft hole wall isnot only for the needs of engineering design, Therefore the study has important theoreticalsignificance and application value for the structural innovation.The main research object of study is the wall-format shaft hole wall structure, take one ofthe cross study its seismic shear performance, this article mainly considered the influencingfactors such as the section width-thickness ratio of the wall-format shaft, reinforcement ratio,axial compression ratio and the hole ratio of the hole wall etc. In this paper, the majorresearch works are summarized as below:(1). This article briefly describes the development couse and research status of thewall-format shaft hole wall, and introduces the shear mechanism of reinforced concretestructure. This article analyze the shear capacity of the wall-format shaft hole wall usingnonlinear finite element mathod, comparative analysis of the resulting data with national norms, proves the authenticity of the finite element simulation.(2). This article designs different cross-sectional form according to the differentinfluencing factors of this structure, and load analysis was carried out on the13models,studied the effects of various on the structure, laid a foundation for further study of thestructure.(3). According to the results of this article, engineering proposal is provided for the sheardesign of the wall-format shaft hole wall structure。...
