Analysis of Influence Factors on Wind Resistance Stability of Long-span Bridges

Abstract

Long-span bridges (LSB) are common in the developed coastal areas, which is an important node of economic operation. However, LSB often has the problem, such as bridge stability with the condition of wind resistance, which is important for the bridge safety, service life and other important indicators. Therefore, it is meaningful to study and analyze the stability of bridges under wind resistance. This article will from the bridge structure deformation under calm wind load and wind resistance of bridge vibration under these two factors, the research status about the stability of LSB is expounded, and analysis of the specific image factor is applied to bridge structure, how in the end put forward using tuned mass damper (TMD) is used to reduce the influence of bridge vibration on the stability. The conclusion of this paper can be a reference for the design of the wind resistance and implementation of wind resistance measures of LSB.
