The Research On Influence Of Seismic Performance Of Multi-story And High-rise Building With Floor Open Hole Under Rarely Earthquake

With the rapid development of China’s economy in recent years, the development of the construction industry also reaches a new climax. With the building materials performance, and production process constantly improving, and the gradually diversification of the building function, people’s requirements for building use function is also getting higher and higher, and the construction of the building also becomes increasingly complex. In order to meet these requirements, some multi-story and high-rise buildings often have the different degrees of slabs-openings.However, on the researches of the experts and scholars, floor open hole will impact on structure more or less, especially have the a certain effect for the seismic performance of the structure. So the slabs-opening should be attached enough importance in seismic designs.On the basis of relevant theoretical method, this paper selects two models as the object of study: a shear wall structure of high-rise building and a frame structure of multi-storey building. After the proper simplification of the models, we use the PKPM-SAUSAGE program software to analysis the elasto-plastic time-history analysis of the rarely earthquake. The main contents of this paper are as follows:The first chapter introduces the development of the multi-story and high-rise buildings, and the common building structure systems are also briefly introduced. At the same time, the the seismic design ideas are briefly outlined, leading to the main purpose and significance of this study.In the second chapter, some basic methods of seismic design are studied, which provide a theoretical basis for the following analysis.Chapter three: introduce the principle of the finite element analysis software PKPM-SAUSAGE briefly, which will be used in this paper, and select an appropriate seismic wave for the model to analysis.Chapter four : select a high-rise building engineering, by the proper simplification of the shear wall structure, several models were established with different floor opening form. Then the paper uses PKPM-SAUSAGE to analysis elasto-plastic time-history analysis of the rarely earthquake. At last, compares and studies the impact of different slabs-opening form on the seismic performance of the structure.Chapter five: select a multi-story frame structure building, by the proper simplification of the structure, several models were established with different floor opening form. Then the paper uses PKPM-SAUSAGE to analysis elasto-plastic time-history analysis of the rarely earthquake. At last, compares and studies the impact of different slabs-opening form on the seismic performance of the structure.Chapter six: According to the research contents and the analysis results of this paper, analysis the impact of different slabs-opening form on the seismic performance of the structure, the paper wishes put forward some opinions and suggestions for the seismic design of the structure.
