STUDY ON STRUCTURAL DESIGN OF SPECIAL-SHAPED FRAME

A special-shaped frame structure system is developed based on common frame structures.By setting fringe component on the structure,the stiffnesses of frame column,beam and beam-column joint are increased,and therefore the whole stiffness of frame structure is also enhanced.It includes special-shaped frame-frame structure,special-shaped frame-shear wall structure,etc.It can solve the shortage in displacement of simple frame structure or frame shear-wall structure effectively,and adjust the plane rotation.The whole distortion and bearing of special-shaped frame structure are analyzed,and yielding order of component is brought forth,which can increase the line number of earthquake defense.
