摘要：Structural connections are modeled as hinged or rigid. However, hinged connection carries some moment and rigid joint has some flexibility. This is recognized by concept of semi-rigid connections in building codes. But, there is no practical tool for analysis of the structures with the semi-rigid connections as any connection has its own behavior which is not mathematically well defined. This research concerns on using fuzzy theory for analysis of the structures with semi-rigid connections. It is illustrated that rigidity of a connection can be modeled as a fuzzy number or linguistic variable. The fuzzy stiffness matrix and solving the equations is studied. Several structures were analyzed by a computer program and conclusions drawn.
