Introducing innovative force limiting device based on reduced length buckling restrained brace

Space structure is referred to a structural system that involves three dimensions. These structures provide the best solution for covering large, column free areas. The popularity of space structures is mainly derived from their appearance, ease of erection and economy of them. Buckling and post-buckling characteristics of space structures greatly influence their stability. Space structures have tendency to collapse in a brittle manner due to buckling of a number of critical compression members. Force limiting devices can be used to improve the post-buckling characteristics of compressive members. In the present study, an innovative force limiting devices is introduced and their behavior in pressure is investigated by ABAQUS finite element software. This type of force limiting device is designed based on reduced length buckling restrained brace
