Structure and Stress Mechanism of Snti-buckling Support for High-rise Connected Structures

Abstract

This article explores the characteristics, composition, and design requirements of high-rise intelligent buildings, analyzes their superiority and social benefits, and studies their construction principles and future development trends. It is people-oriented, device-oriented and function-oriented. The original three major structural systems have been increasingly unable to meet new requirements. This paper seeks a new seismic system that is both safe and able to protect the instruments and equipment inside the building, and can be connected to the main structure of the structure for normal operation and economically. After a thorough discussion of the latest proposed seismic design methods and performance-based seismic design, this paper proposes performance-based structural seismic design countermeasures with the characteristics of high-rise intelligent buildings. Determine the target performance according to the owner’s requirements and building functions and investment benefit criteria; then determine the safety indicators of the high-performance intelligent building based on the performance structural design; compare the three optimization decision models for the reliability of the performance-based structural targets; An evaluation model of initial cost, inspection and maintenance costs, and failure loss costs. A reliability optimization decision-making model based on performance and earthquake resistance for a high-rise intelligent building is established. The research results show that the maximum displacement of the model structure in the X direction is 14.8mm and 13.8mm, and the maximum displacement in the Y direction is 13.7mm and 12.9mm, respectively. The maximum displacement of the latter in the X and Y directions is compared with the former. From the perspective of the curve change, the displacement change curve of the anti-buckling support frame is always smaller than the displacement curve of the ordinary support frame.
