The study explores the feasibility of a new all-steel buckling restrained brace (BRB) with the double pre-tensioning system as an alternative to conventional concentrically braced frames by using finite element method (ABAQUS program). And to verify modeling. use U-V1 specimen results and compare them with test results. The restraining element in an all-steel BRB is built from a recta... https://www.isbasvurusuyap.com/product-category/cafeteria-fast-food-trays/
