Abstract
In this study, the theoretical basis and evaluation index of the seismic performance of concrete structures are deeply discussed, and the behavior characteristics of concrete structures under earthquake are systematically analyzed. We study the basic requirements of seismic design, fortification standards and design principles and criteria, define the core concept and method of seismic design, and then elaborate the evaluation index of seismic performance of concrete structures, including strength index and deformation index, to provide a scientific basis for evaluating the seismic performance of concrete structures. The principle, applicability and advantages and disadvantages of various reinforcement methods are discussed, including the reinforcement method with increased section, the reinforcement method with steel cladding, the reinforcement method with fiber paste and the method of crack grouting and sealing. In addition, we also conduct an in-depth analysis of the existing problems in the seismic performance of concrete structures, involving design standards, material properties, construction quality and maintenance management. To solve the above problems, this study puts forward some strategies to optimize the seismic performance of concrete structures, including updating design standards, improving material properties, strengthening construction management and regular maintenance inspection. These strategies aim to improve the seismic performance of concrete structures and reduce the loss of earthquake disasters. Through this study, we aim to deeply understand the seismic performance of concrete structures, explore effective seismic reinforcement techniques and optimization strategies, and provide theoretical support and practical guidance for improving the seismic capability of concrete structures.
