Analysis Of Seismic Response And Energy Dissipation Of Irregular Concrete Frame Structures

Due to the emergence for the large number of irregular structures,the seismic performance of the structure can not meet the requirements of the specification.In order to solve this problem,this thesis puts forward the energy dissipation technology,which can make the irregular structure meet the requirements of the seismic response.First,this thesis introduces the concept of irregular structure,the concept and principle of energy dissipation.By using the FORTRAN90 language program,we have prepared the analysis program of the stiffness matrix of the energy dissipation and shock absorbing structure,we solved the difficulty of solving the stiffness matrix of energy dissipation and shock absorber,so we provided a more practical calculation method for the energy dissipation structure analysis.Then,the modal analysis and seismic dynamic analysis of the irregular high-rise frame structure are carried out by self-programming.The results are compared with the results of SAP2000 simulation,and the correctness of self-programming is obtained.Due to the simplicity of operation for the self programming,the design of the energy dissipation structure will be more practical.Finally,two kinds of software are used to calculate the dynamic response of the energy dissipation structure.We obtained the displacement and interlaminar displacement angle of the structure.Compared with the calculation results of the original structure and the energy dissipation structure,we can find the superiority of the energy dissipation structure which has a very good application prospects.The main contents are follows as:1?The concept of irregular structure and energy dissipation introduced in this paper.Through these learning,we can know that it is necessary that the development of irregular and energy dissipation technology with the Era development,and the irregular structure and energy dissipation technology has good application prospects.2?Seismic theory method and Three common seismic calculation methods introduced in this paper.We can know that the calculation steps and process of structural dynamic analysis by the study of these theories.We can get the corresponding results by using these theories to calculate engineering examples.3 ? A software of solution computing structure lateral stiffness matrix program is established by using the method of inverse flexibility matrix.We can solve the energydissipation structure stiffness matrix to solve difficult problems by use it.We can establish a program to solve dynamic analysis of energy dissipation structure by numerical integration method for time history analysis.4?Using Fortran90 program and SAP2000 software to calculate the dynamic response of the original structure,then compared the results of the two software,we can analyze the correctness of the program,and the correctness of the SAP2000 software modeling.5 ? We can get the result of the dynamic response of damping energy dissipation structure by using two kinds of software.Compared to the result of original structure and energy dissipation,we can get the conclusion that it is the superiority of the energy dissipation damping structure,also,there is a good developing prospect in the future for the energy dissipation structure.
