CONTINUAL VARIATION OF THE DISPLACEMENT AND GENERATION OF LIMIT STATE FUNCTION FOR EXISTING STRUCTURE
Aiming at the insufficient research of reliability analysis on stiffness of system, based on the design principle of limit state provided in the Chinese structural design code, in which the designed structure allows no appearance of deformation that influence the normal usage of structure, the method of continual variation on displacement of frame structure is derived. The method was combined with probability calculation and numerical analysis and recurrence formula. It is used to continually generate internal force and limit state function of the displacement for continual variation structures. The repeated assembly of global stiffness matrix and repeated inverse matrix are avoided in this method. A new criterion of degenerating the structure into mechanism is introduced. An accelerating calculation method of reliability analysis on system stiffness is presented.
