Knowledge based design tool of steel structures including economical and structural aspects

Abstract: The paper deals with a knowledge based expert system (KBES) developed for the design of structural steel joints. The KBES can be used for the selection of suitable joints taking into account the expert knowledge stored into the database. The expert knowledge is so far shallow and it contains force transmitting abilities, fabrication and erection cost differences of joints. The KBES is used also for the choosing of suitable values of joint parameters by taking into account both generic rules (appearing in the codes of practice) and specific rules of individual joints and the combinations of both of these rules. The KBES suggests also local analysis models of the joints. The KBES gives an estimation of cost of the whole skeleton by combining the product model (PM) of the material entities and the cost database. The product model for the analysis of the whole steel skeleton is also proposed by the KBES. The PMs are made following IS0 10303, so we are working in an open environment.
