| It is widely used in the domestic short pier shear wall structure of the building,especially in high-rise buildings. Compared with ordinary wall, not only to reduce the unit area amount of reinforced concrete, and thus reduce weight, interior layout flexibility, can help achieve architectural aesthetic effect, greatly reduce the construction cost. But consider the case of 7-degree earthquake zone, there are many short board between short pier wall. Operation through modeling analysis of engineering examples, we can see the presence of a large number of design, construction, cost and other problems in practice, to demonstrate our comprehensive on short pier wall is also inadequate, especially in the state structure under seismic performance analysis, and elaborate short shear wall and engineering applications discovered, and programs to solve practical problems.The main contents include the following aspects:(1) The first chapter introduces the current domestic and international high-level short shear wall residential development needs, from the perspective of the structural analysis of the short pier shear wall structure and determination of ordinary shear wall structure definition, mechanical characteristics and seismic performance. Analysis of the difficulties and problems encountered short shear wall design, propose ideas and solutions to problems,and innovations in practical application.(2) The second chapter describes the overview of the project, the value of the load,seismic action coefficient input parameters, and structural analysis period ratio,displacement ratio, angular displacement, stiffness ratio between layers, inter layer shear capacity just heavier than the shear weight ratio illustrate the physical meaning of values,but also put forward economic indicators project evaluation methods.(3) Chapter III, in consideration of 7 degrees seismic zone conditions assumed in simplified terms, the use of short-limb shear walls, shear walls two schemes are established model, in accordance with its current design specifications, Compare SATWE SAP2000 software and the results of its comparison of important parameters of mechanical properties under earthquake differences. Research on the structure El.Centro wave,Lanzhou wave, under the Tangshan three seismic wave response time history and spectrum analysis and the results were compared. Propose solutions to the problem of short limb shear wall design Several methods are summarized in short shearing wall stress analysis features.(4) The fourth chapter, first short pier shear wall shear wall Engineering and general consumption calculation, and the angle through value engineering analysis, quantitative analysis, and the results showed that: Both structures were to meet the seismic performance of the new regulatory requirements, overall performance short shear wall structure of the superiority of the conclusions. Secondly, summarize short pier shear wall construction method of dealing with practical problems, improve construction quality and speed up the construction schedule.To sum up, we can get the conclusion is: With the seismic performance improved short pier pier pier shear wall structure of their shorter, but higher than its ordinary reinforced wall structure, the cost of narrowing the gap. Some examples of engineering problems raised by this paper, seismic performance and economic analysis of shear wall structure for processing, and high-rise residential structures in the future about the spatial layout of the design selection, provide some basic support for the structural design and investment decision making. |
