Intelligence Aided System For Safety Assessment Of Buildings On Sit

In recent years, safety assessment of buildings in post-earthquake is paid extensive attentions in China. With the publishment of national standard "safety assessment of buildings"(GB 18208.2-2001), the assessment becomes standardized. In this paper, some research in the damage of buildings in post-earthquake field has been done in such fields as the relationship of different influences, the method of measurement, the method of safety evaluation, the development of aided decision system and so on. Concrete studies in this paper are as follows:Three main factors and their correlative other factors to the building's safety in post-earthquake field are ascertained. According to the inherent relations of all factors, a chat of the factors which influence the building's safety is systematically established.According to the national standard "safety assessment of building" (GB18208.2-2001) and the prescript of all kind of safe building's earthquake damage state and by using expert's field evaluation method, the estimation vectors of affecting building earthquake damage' every basic factor in every state are directly given. Thereby, the measure method and evaluation standard problem of building safety assessment in post-earthquake field which is subjective and fuzzy are preliminarily resolved.Second-class fuzzy synthetic evaluation method of building earthquake damage in post-earthquake field is established by analyzing traits of these problems treated by experts and fuzzy decision method,which resolve decision model of this complicated system with manyfactors and many layers and qualitative and fuzzy altogether. So traditional earthquake damage evaluation method based on expert's experience is promoted to science decision method.Combining fuzzy synthetic evaluation model of building earthquake damage with formation idea of experts system, applying programs, such as VB and VBA, Intelligence Aided System For Safety Assessment Of Buildings On Sit is developed (rudiment). This system provides user an alternant condition with convenience and directness and wieldy by adopting multi-document interface(MDI) based on graph user interface (GUI), and auto transforms assessment results to Word report. This system is mainly applied in direct safety assessment of buildings in post-earthquake field. At last, this system is validated by two examples, the result is consistent with expert's experience judge.
