MTHA for Bridge(s) Supported on Cables

Abstract

The desire to have long to super-long bridges has immensely increased with the development of the infrastructure during the past decades. Cable-supported bridges, comprising Cable Stayed and Suspension Bridges, generally constitute Long to super-long-span bridges. In the current global competitive scenario, the need and the importance of different materials and techniques are incorporated for an enhanced cost-to-utility pointer. As an introductory and generalized attempt, predominantly used cable-supported bridges are CSB’s and SB’s for bridges of long to super long spans are generally in 0.1 km. CSB’s and SB’s have their own merits and demerits. So as an innovative approach, preference for CSSHB may be given as it incorporates the merits of both CSB and SB, respectively. This article tries to restrict the study to evaluate the effect of innovative forms of cable systems adopted on the modal period of the cable-supported bridge model (studied).

The author used the SAP2000 modelling program. The study examines the bridge model's reaction to innovation and variance in the cable system. A bridge that resembles the Bridge at Ling Ding Strait in China is used as a model. The original cable-stayed bridge, as well as suspension type, composite bridges, and cable-stayed suspension hybrid bridges, are all represented in models with different cable systems. The findings showed that choosing a cable system has a significant impact on modal time.
