Performance-based Seismic Design Of Over-limit And Super High-rise Concrete Structures ——Take Hengyang Greenland Intercity Space Station 1# Building As An Example

This paper adopts the performance-based seismic design method of the structure,mainly taking the Hengyang Greenland Intercity Space Station 1# building as the engineering background,and specifically discusses the over-limit super high-rise frame-core tube structure,and conducts an in-depth discussion on the key issues and complex points.Analysis,the main work is as follows:1.The relevant basic theories and methods for the design of over-limit and super high-rise concrete structures are described,the general design ideas of concrete structure design are summarized,and the relevant concepts of structural seismic resistance and relevant code points of structural design are briefly described.2.According to the basic theories,methods and design ideas summarized in this article,with Hengyang Greenland Intercity Space Station 1# building as the engineering background,the structure model of this project under different mechanical model software is established,and the parameter values of the structure model are summarized,Calculation and analysis methods and influencing factors,calculated and analyzed the structural models in the two software,and compared various mechanical control indicators,verified the rationality of the structural model,and carried out the structural design of the project.3.According to the relevant regulations and provisions of our country,the project has been judged to exceed the limit,and the seismic performance of the project is checked according to the pre-selected seismic performance targets under the action of various levels of earthquakes,which can meet the expected seismic performance target requirements.Finally,corresponding seismic strengthening measures are proposed for the weak parts of the structure.
