Rigid Frame Bridge

Based on a long-span pre-stressed concrete continuous rigid frame bridge, the Chaoyangsi bridge, the influence on stress and deformation of the girder caused by different closure temperature was analyzed. With the aided platform Midas/Civil, comparative analysis of three different closure temperatures was carried on to determine the reasonable one. It is concluded that different closure temperature has important influence on girder stress, but the most dangerous stress combination of girder under serviceability limit state could be taken as remain the same. Though different closure temperature has little influence on the displacement of girder, it is recommended to pay highly attention to the influence on the mid-span vertical displacement when doing the formwork. And finally this article puts forward some effective measures to prevent and reduce the temperature effect.

The author took Chuanlingdong Bridge in Fujian Province for example. Applying general FEM software ANSYS and sub modeling technique, 3D model of the whole bridge was built firstly, and then closure section and nearby sections in mid-span were built to sub model. In the sub model, initial mesh was refined, weaken effects of corrugated pipes were considered and plain bars also were built. Based on the fine sub model, original design and construction tolerances are analyzed respectively. At last spatial stresses of closure section were cleared and key influencing factors were concluded. This research showed construction tolerances had a great influence on bursting damage when the design was at a disadvantage.

Based on the shortcomings of the continuous girder bridge with single column pier, two-span T-shape rigid-frame bridges with single integral pier and two separated piers are put forward in this paper. Using time-history analysis and considering the material nonlinearity of reinforced concrete of the pier, the nonlinear seismic responses of the three bridge structures subjected to horizontal seismic wave are analyzed. The results show that, compared with continuous girder bridge, the shear forces of the two types of T-shape rigid-frame bridge are bigger, the moments of the T-shape rigid-frame bridges is smaller, and rotation angle of plastic hinge of T-shape rigid-frame bridge is much smaller. The energy dissipation and the anti-seismic capacities of T-shape rigid-frame bridges are better than continuous girder bridge under the condition that the shear resistance capacity of pier is secure.

This paper apply displacement back analysis theory for geometry form monitoring and calculating work of segmental construction of prestressed concrete continuous girder bridge, making use of displacement back analysis method to optimize bridge structure parameters, ensuring accuracy of geometry form control with calculated results of every girder segment in entire construction. This method is used in the construction monitoring and supervision for Yuanyichang circular curved rigid frame bridge on Pingan-Adai highway, to make the closure accuracy and the bridge geometry form reaches the effect of aspiration. Through the result of the finished bridge, what we can obtain is that the displacement back analysis theory could fulfill the requirement of factual project and be widely used for geometry monitoring of segmental construction of prestressed concrete continuous girder bridge.

This paper presents a survey of construction techniques for pre-stressed concrete (PC) box-girder bridge with corrugated steel webs in recent decades. The structural forms of the bridge have experienced simply supported beam bridge, continuous girder bridge, cable-stayed bridge and the continuous rigid frame bridge. Meanwhile, the construction technologies were constantly innovated, including cast-in-situ, precast and the combination of them. The processing and installation technologies of corrugated steel webs and several typical construction techniques for PC box-girder with corrugated steel webs were elaborated, such as full framing construction, cantilever construction, span-by-span construction, incremental launching construction and some other various innovative ways. The valuable experiences in a variety of construction methods were summed up. The results show that some innovative construction ways should be developed by fully utilizing the corrugated steel webs as a guide beam or a work platform to improve the efficiency of construction.
