China is a country with many earthquakes. Seismic Building Structures safety monitoring and building earthquake-proofing technique are important means to protect the safety of people’s property in China. However, Building Structures up to now, China’s seismic reinforcement and identification technology is still not mature enough. In particular, the 2008 Wenchuan earthquake caused great loss of life and safety to the Chinese people. This paper, takes seismic identification and reinforcement technology of building structures as the research object and summarizes the main methods of building structure seismic resistance in China. This paper is based on an in-depth analysis of the main seismic reinforcement and identification techniques in China, deeply analyzes the crux of anti-seismic and reinforcement of building structure combining with the current building seismic reinforcement typical cases, and puts forward some reasonable suggestions and improvement methods for the future development of building seismic identification and reinforcement design.

In recent years, the development of seismic technology and design of building structures in China is getting more and more rapid. People’s requirements for building seismic reinforcement are also increasing. At the same time, China’s seismic design standards are higher and higher. But because of the reality of the national conditions, many old neighborhoods of the last century are still widespread. Their earthquake resistance and safety are important hidden dangers to people’s property and safety. Once the earthquake occurs, the former community seismic resistance cannot meet the current requirements, so the safety of people’s lives and property cannot be guaranteed. Therefore, it is necessary to carry out seismic identification of the old communities, which also meets safety requirements. The following is the author’s elaboration of the building structure seismic reinforcement and design, hoping to contribute to the development of building seismic technology through author’s analysis and demonstration.

Throughout the history of seismic identification and reinforcement design in China’s construction industry, the process is divided into three stages. The first stage was during the Xingtai and Tangshan earthquakes of the last century. At that time, China did not formulate strict seismic standards. Most of the construction houses in China were distributed by enterprises and the state, and there is no concept of commercial housing. At the same time, China’s construction industry has not formed a scale. As a result, the Tangshan earthquake has caused serious damage to the safety of Chinese people’s lives and property. It also improved Chinese people’s understanding of seismic identification and reinforcement, and sounded the alarm bell for the development of building seismic resistance in China. This stage is the initial stage of building seismic reinforcement and identification in China. With the introduction of building seismic codes and formulation of seismic labeling, the 1990s was a period of rapid development of building seismic resistance in China, and it was also the second period of seismic identification and reinforcement design in China. The period is the foundation period for the development of China’s building seismic industry, which has laid a foundation for the reinforcement and development of subsequent seismic standards. At this stage, China’s housing construction issued special seismic standards. In 1978, China promulgated the codes for seismic design of industrial and civil buildings. The code provided technical support for building seismic design in China. At the same time, the standards for aseismic identification of industrial and civil buildings were also issued. The introduction of these two standards has promoted the development of building seismic engineering reinforcement and design in China, which also provides technical support for the reinforcement of a large number of houses in China. The third stage was after 1989. China successively revised the codes for seismic design of industrial and civil buildings of the 1978 edition. In 1995, China’s ministry of housing and construction also revised the standards for aseismic identification of industrial and civil buildings. In this stage, the combination of seismic design codes and identification standards pushed the building seismic to a new development stage [1] .
