The performance of static and dynamic characteristics and the role of the cable-stayed continuous rigid-frame structure in hybrid structure are analyzed in detail;a comparative analysis of the dynamic characteristics of the bridge is taken for the girders with or without consideration of prestressing.

With the development of inclined pull truss T structure, inclined pull consecutive beam and inclined pull consecutive truss, a new structure system has come into being in our country, which is the inclined pull truss initial concrete structure system.

In the 3×17m skewed rigid continuous girders practice in newly built Yongtaiwen passenger special line, in allusion to continuous girders construction over river, the Bailey girder is used as cast-in-site scaffolding with mechanical lifting, so that the intensity of labour is reduced, the construction period is shortened, and the cost is reduced too, therefore the economic benefit is obvious.

This paper presents the construction design of vertical swivel erection of the flexible steel tube arches for 2×275-m span continuous rigid-frame structure of the main bridge of Yichang Changjiang River Bridge on Yichang-Wanzhou Railway.

The approach spans of Fumin Bridge in Shenyang are composed of 30-m span pre-stressed concrete continuous rigid-frame structures, of which the main girder is designed as triple cells single box section of constant height, and of long cantilever and inclined webs.

This paper introduces the construction control flow and construction control contents of the continuous rigid-frame structure with span arrangement(140+268+140) m of the auxiliary bridge of Sutong Bridge and also provides the construction control essentials of long span continuous rigid-frame structures.
