Abstract

Static Characteristic Analysis of Concrete-filled Steel Tube Tied arch bridge

Highlights

  • Since there are obvious advantages such as reasonable mechanics performance, light weight and neat crisp outline, etc., prestressed concrete (PC) continuous box girder has been widely used in China, especially when the span is not too large (

  • Based on the background of a bridge in service, the structural mechanic performance will be discussed due to the change of tendon tension pattern caused by the limit of site condition

  • In theory the influence to support cast in place prestressed concrete continuous box girder caused by the change of tendon tension pattern is mainly embodied in the pre-stress loss [5,6]
