New Method Of Seismic Damage Prediction Of Single Building

Seismic damage prediction of engineering structures is a new developing subject, and the problems that it will solve is quantitative estimation of the losses and distribution of economic, such as the destruction of buildings and project facilities, and casualties, which is probably caused by the earthquake in the future, in the nationwide or within one area, based on the hazard analysis of earthquake, seismic zoning, vulnerability analysis of structure. Seismic damage prediction of engineering structures is a basic work and important basis of making earthquake disaster reduction plan, earthquake emergency scheme and the goal of Earthquake Preparedness and Disaster Reduction. The content studied in this paper, which is based on seismic damage predictions of different Single Buildings, is just a part of seismic damage prediction of engineering structures. And a relative convenient method of seismic damage prediction of Single Building is discussed in this paper.In China, there have been some methodologies on seismic damage prediction of single building such as historical seismic damage statistics, specialist evaluation, semi-experience and semi-theory, fuzzy analogy, structural theory etc, while many of which are relatively tedious and need a heavy workload. Based on previous work, the main work is as follows:⑴. The reasons that structures destroyed in the earthquake are summarized and the main impact factors of seismic damage of structure is selected.⑵. The theory of fuzzy evaluation and its application in the earthquake is recommended.⑶. The relevant materials of seismic damage prediction of the most cities that are collected by the group in the country are compiled, and then the regional database of seismic damage prediction of different structures is set up.⑷. The seismic damage impact factors (including Structure type, Built year, Story number, Site type etc) are defined. In addition, the influence that impact factor plays and its calculation method is also introduced in the paper.⑸. According to fuzzy evaluation model, the method of seismic damage of single building of multi-factor analysis is established, and the main advantage is capable of gaining seismic damage of single building relatively simply and feasibly. And the reliability of the results that are compared with previous results of single building is relative high.⑹. The sample compositions and function modules of database query system are introduced in the paper.⑺. The seismic damage impact factors of multistory masonry structure and multistory reinforced concrete frame structure are calculated in the chapter four and the influence that impact factors impose to seismic behavior is compared respectively.
