| Abstract: | The stiffened framework construction method is commonly used in the long-span concrete arch bridge in recent years.According to a newly built crossing-river bridge in Fujian,the article briefly introduces the layout and construction of the stiffened framework,and discusses three simulation methods of the stiffened framework commonly used in the calculation of construction stage.The calculation and comparison results show that the beam-slab composite model is sufficiently accurate and dependable. |
