【Abstract】 This paper introduces bridge section model tests in the wind tunnel.It presents static forces on bridge section models.The effects of bridge fences,isolation belts and different model lengths on static forces are studied.The static and dynamic stabilities of bridge are analyzed.The results show the effect of bridge fence,isolation belts and different model lengths on static forces should be considered in wind load design.更多还原
