Application And Economic Analysis Of Viscous Damper And Buckling Restrained Brace

Traditional anti-seismic structures resist the seismic action by enhancing the seismic performance (strength, stiffness, ductility) of the structure, namely the storage and consumption of seismic energy through the structure itself, which is a passive anti-seismic measure. At present, some energy dissipation design methods recommended at home and abroad have their own merits, but these methods pay attention to the theory, despise practice; and our standard design of damping structure is put forward principle and framework regulations, not easy to operate. Therefore, it is subjected to certain restrictions on the practical significance, for the general engineer, it is difficult to start the design of energy dissipation structure, the application and engineering technical and economic comparison of different damping system are inadequate. Considering the above factors, combining with the actual project, it is necessary to propose design method in the same project using two different damping system which are fluid viscous dampers and anti buckling support, and analysis its engineering economy, at the same time, it also can provide a reference basis for the structure design personnel.The design of Kunming University of Science and Technology Xinying campus undergraduate teaching and training center building of Yunnan province are analyzed during the paper, and the two kinds of different damping system are analyzed and designed, through in-depth comparative study, so that the structure can meet the seismic design objectives. The research contents are as follows:1. It describes the research background, purpose and significance of the source, at the same time, the application of different damping system is analyzed and summarized, and introduces the basic situation of the viscous fluid damper and anti buckling restrained brace.2. The second unit of Kunming University of Science and Technology Xinying campus undergraduate teaching and training center building is as the engineering background, introducing the main content of the design of the concrete structure, different types of structures are analyzed and compared, and the undergraduate training center building was introduced, including the basic situation of project, building the safe grade of the structure and the design service life, natural conditions, the design standards of this project,, norms, procedures, standard value of the uniform live load, the main material of the structure etc..3. The design and calculation of viscous fluid damper in this project are introduced. Including:(1) determining the type of damper, damping coefficient, damping exponent, maximum power, maximum speed, maximum range, hysteretic stability performance indicators for the project; (2) introducing the design method of fluid viscous damper in this project; (3) using PKPM software modeling, and checking the seismic capacity; (4) analyzing the calculation results, and making evaluation.4.

Comparison effects of the two kinds of different damping system which are viscous fluid damper and buckling restrained brace, used in the same building. Analyzing from the two aspects that include design and construction, to make the evaluation of the result.6. Making a comprehensive evaluation about the engineering economy brought by fluid viscous damper and buckling restrained brace which are two kinds of different damping system, solving the security and economic issues that is concerned, and providing some basis for future design.
