Analysis of Mechanical Property of Taniguchi Bridges in Mountainous Areas Loaded by Fluctuating Wind

Besides live loads like cars,earthquakes and people,wind loads should not be neglected on small bridges in mountainous areas,especially by taniguchi and mountain pass.This text does an analogue computation taking a typical slant legged rigid frame bridge in a mountainous area of Chongqing. This bridge lies in the taniguchi of mountainous area where wind condition is complicated.Mathematical model conforming to the local wind load should be established according to the meteorological and hydrological conditions of the bridge site and hydrodynamics and energy conservation principle in order to truly reflect the actual condition of wind in bridge site. Comparing with the calculating result by ANSYS and model of static wind load for normal design, it shows that model of fluctuating wind load established almost accords with the model of static wind load which provides a new train of thoughts and method for further promoting the model of wind load to lead the wind-resist design of bridge construction of taniguchi in mountainous area to better approximate to the real facts.
