The superstructure consists of Module geometry is illustrated in Figure 1. The length of typical segment is limited to 3. Application of the glue on the face of the erected segment as well as new segment is carried out by experienced construction workers. Anchor saddle boxes are provided at upper pylon which provides individual support for each strand and avoid lateral pressures due to grouping of strands.
Application of the glue on the face of the erected segment as well as new segment is carried out by experienced construction workers. On erection front, segments per months are achieved with help of 3 sets of BridgeBuilder. In order to study the dynamic characteristics of a super-long-span cable-stayed bridge which is semi-floating system, the spatial finite element model of this cable-stayed bridge was established in ANSYS based on the finite element theory. Steel diaphragm and stiffening rib of the multi-box steel- concrete composite bridge can improve the flexural capacity of bridge to some extent, so these contributions should be reasonably considered during the design stage in order to reduce the engineering cost. Alignment is carried out followed by dry matching the segment to the exact position by adjusting with hydraulic jacks. This layout is currently in modification phase due to increase in the number of segment casting mounds.
In current scenario, many structural configuration options are available for bridge structure. Module geometry is illustrated in Figure 1. Providing rigid joinery and additional bearing capacity to bridge span.
Stay cable extradosed system-Dyna-Link Anchor box stay cable system, Post-tension bar stressing. Ease in construction can determined by the ongoing process, which is at segment casting yard- with six moulds and 3 to 5 days of casting time cycle for segment, average segments casting is observed.
Power spectral density analysis of the measured signal was done with frequency domain analysis methods. Stay segment takes five days due to complex reinforcement and other guide-pipe arrangement in blisters. Average 2 days erection cycle is achieved in normal site conditions.

Epoxy glue is mixed with a mechanical thhesis. The vertical displacements of the Ai-Lan bridge corresponding to ambient vibration due to traffic loads are remotely monitored.
The study results provide the theoretical basis for the optimization design of suspension arch bridge. The studies are as follows: Stay-cables and post tensioning systems are provided to have structurally sound deking system. The box girder is transversely post-tensioned against live load effects thesid eliminate cracking in the top slab and to provide increased durability. Construction methodology adopted reduces the construction duration and economizes the overall cost.
Bridge span-construction is a complex activity involving different phases shown schematically in Figure 3. T Bars with the coupler is being thesie in the previous segment. Total three number of cell pre-cast RCC box Having of PT tendons, in both longitudinalas well as transverse direction is In order to study the dynamic characteristics of a super-long-span cable-stayed vridge which is semi-floating system, the spatial finite element model of this cable-stayed bridge was established in ANSYS based on the finite element theory.
The erection procedure includes 4-cyclic activities, which are listed below. Stay cables are anchored at the edges of box girders to support them which are later deviated in short pylons. Log into your account.
Concept is more or less module based design, where nine numbers of pylons having balance cantilever extradosed design along with two abutments makes the bridge. So, erection process will be for both arms of pylon. As its name suggests, the stressing which is going to remain permanently are classified in this stressing, which is a combination of partially stressing PT Bars and majorly PT Tendons. The actual service state of the bridge is analyzed by the comparison of experimental and calculation results.
As in described in geometry, transverse as well as longitudinal tendons are there for post tensioning purpose. Static load test was carried out on Bgidge interchange ramp bridge of Lin-Chang expressway. The 3rd Narmada bridgeis taken as a case-study in this paper to describe components and functioning of an extradosed structure.

Segment stacking yard is planned adjacent to segment production area. Can I find this reference: Bridve cantilever construction method is used to erect the box girders with epoxy joints between segments.
