Performance-Based Structural Seismic Method in High-rise Building Design

Abstract

The rise of intelligent buildings in China is based on two reasons. One is that with the reform and opening up, China’s national economy has continued to develop rapidly, its overall national strength has been continuously enhanced, and people’s living standards have been improved. People urgently need to improve and enhance their working and living environments. Architecture is just one of the important ways to meet this demand. Performance-based seismic design is based on the investment-benefit criterion as a basic principle, reflecting an important change in the seismic design thinking of modern structures, that is, focusing on structural safety from the past. To develop a comprehensive focus on structural performance, safety and economy. It makes the seismic design transition from macroscopically qualitative goals to concretely quantified multiple goals. Designers can choose the required performance goals, which is conducive to the innovation of building structures, using new structural systems, new technologies, and new materials; it is beneficial to adopt different performance goals and earthquake resistance for different fortification intensity, site conditions, and the importance of the building Measures. It is a change in the design concept and plays a significant role in the design and development of engineering structures. This paper explores the characteristics, composition, and design requirements of high-rise intelligent buildings, analyzes their superiority and social benefits, and studies their architectural principles and future development trends. High-rise intelligent buildings were born to meet the higher requirements of office and living environments. It is a combination of architectural art and information technology. It is the four basic elements of structure, system service and optimal combined system management, providing a safe, efficient, comfortable and convenient built environment. At present, only the uncertainty of the load, the strength of the material, the geometric dimensions and the uncertainty of the calculation model are usually considered. For the artificial uncertainty, the complexity and uncertainty of the economic loss estimation due to the complexity of earthquake damage As a result, it is very difficult to accurately estimate economic losses, especially the estimation of indirect losses. Therefore, the establishment of a performance-based reliability optimization decision-making model for high-rise intelligent buildings requires further research and improvement. To build more detailed and specific models for different types of requirements.
