| Abstract: | The equivalent calculated length coefficient is introduced and its formulas are deduced in the overall stability design of the bi-overhanging beam. Then formulas of the overall stability coefficient of the overhanging beam is also deduced from the equivalent calculated length coefficient in accordance with the design code of the steel structures. The integrated and precise design process and formulas are offered. |
