The Reasonable Study Of Shear Wall Quantity And Position In The Shear Wall Structure

With the development of economic and technological, the high-rise buildings everywhere in our country, shear wall structure as a structural system has been the most widely used. Because of its strength, integrity, and the lateral deformation and other features, applied to a large number of residential and hotel construction. In the context of rapid development, designers tend to be more walls arranged to ensure adequate security structure. With the strengthening of cost-saving awareness, although such an arrangement security, but also appears to lack of stamina. Therefore, the structure of the wall shear explore the location and number of reasonable arrangement had the necessary theoretical and practical significance. The purpose of this paper is to explore the influencing factors of shear wall quantity and minimum number of shear wall structure, and by optimizing the number and location of shear wall design is both safe and economical structure. The main contents are as follows:First of all, the relevant theoretical knowledge shear walls, including the shear classification and methods, as well as the mechanical properties of different shear walls. In this category, based on the use of materials and continuous methods mechanics calculation method of internal forces and various types of shear displacement. Finally, shear wall structure according to whether they contain wall frame, do two types of analysis and calculation of shear wall structure.Secondly, to explore the reasons of the reverse structure, gives the torsional stiffness formula. Use examples of the impact of location on the wall just heart, mentioned the importance of the position of the shear wall structural integrity, as well as the impact of different positions shear structural performance.Then, using finite element analysis software for real engineering work, study the shear number of related factors, such as the hole rate, wall thickness, concrete strength. Quantitative analysis of the structure of the natural cycle, maximum story drift angle, as well as the relationship between changes of mechanical properties of seismic shear and shear than just weight heavier than other parameters as well as the lateral stiffness and structural factors. Finally, the impact storey building layers and also made the corresponding analysis.Once again, From the angle of displacement control, the aspect ratio is not greater than 4 of the shear wall structure, depending on the height, design earthquake grouping, seismic intensity and site classification of buildings, then limit the interlayer displacement, deduce a reasonable amount of shear wall shear wall structure simplified method.The last, it Use the findings of the previous section and regularity, optimization of a structure layout of the building, contrast analysis of the structure of the cycle, earthquake shear force, axial compression ratio and mechanical characteristics parameters, such as steel weight of the economic indicators. At the end of the article contents always ask detailed summary, the paper also has to be less than delve into the issues raised prospects.In conclusion, this paper studies the optimization of shear wall structure, has important guiding significance to control cost, to provide a reference for the similar engineering design.
