EXTRADOSED BRIDGE THESIS

Butterfly-Shaped rail terminal to offer airport-like facilities at Byappanahalli. I was there in as an german intern Civil Eng. Merger of both bridge configuration leads to economical bridge construction in terms of design and construction costs savings. Application of the glue on the face of the erected segment as well as new segment is carried out by experienced construction workers. The study provides the initial technical files and the basis of acceptance, operation, maintenance and management for the bridge.

Two MT capacity gantries for handling of segments are erected on track beam supported on RCC raft. The studies are as follows: But longitudinal tendons are provided during erection, here it is noticeable that the tendons are provided starting for one end to another end every time in erection. Transverses slope of 2. Vertical pile capacity is duly modified for scour condition by considering overburden pressure from scour level. Stay cable extradosed system-Dyna-Link Anchor box stay cable system, Post-tension bar stressing. Save my name, email, and website in this browser for the next time I comment.

Transverse post-tensioning provides further reduction in the slab thickness compared to reinforced concrete slabs and facilitates reduction in segment weights for handling.

Evaluation of the Dynamic Characteristics of an Extradosed Bridge Using Microwave Interferometer

Top of pile cap is at low water level. This tendons acts as vanes distributed through pier-table. PT bars are stressed in same manner but this time with higher forces and locking nut is also being installed to remain that stress. Segment top beam is fixed to the segment with the help of lifting pins. The Precast Segmental BridgeBuilder is designed and adopted for balance cantilever precast segment erection.

As in described in geometry, transverse as well as longitudinal tendons are there for post tensioning purpose. These bars are connected throughout five segments and then stressed by placing hex-nut and tightening it up to desired pressure.

The study provides the initial technical files and the basis of acceptance, operation, maintenance and management for the bridge. In the super-structure of the main bridge, three-cell of precast segmental box girder with depth of 4. The Extradoses bridge length is m, which is divided into 10 spans with extradosed arrangement. For vertical displacement between two adjacent cantilevers, a shear key is provided at the expansion joint. The dynamic characteristics of this super-long-span cable-stayed bridge were then analyzed.

In this paper, based on the Guangzhou Pazhou Bridge ,the acceleration and dynamic deflection was tested synchronously under normal operating conditions.

Then segment is pulled in forward direction. Erection of segment on any pylon will start from expansion side segment.

Extradosed type Bridge structure Specific Technology: The superstructure of the bridge is cast-in-place prestressed thewis continuous box-girder. This paper addresses the design characteristics and construction methodology for bridge decking in extradosed bridge structure. Case Study of 3rd Narmada Bridge, Bharuch.

Thesis on Extradosed Bridge

In this mode loaded Puller tractor is just aligned to the orientation of bridge segment. The study results provide the theoretical basis for the optimization design of suspension arch bridge.

Means some of the tendons can travel up to half-span length or more. 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. Stay segment takes five days due to complex reinforcement and other guide-pipe arrangement in blisters.

So, erection extdadosed will be for both arms of pylon. T Bars with the coupler is being connected in the previous segment.

I have a question:.

The studies are as wxtradosed Lifting holes are provided in design and left during casting of segments, and with help of both of lifting cranes slings and de-shackles segment is lifted and moved to loading bay. Two MT capacity gantries for handling of segments are erected on track beam supported on RCC raft. Hello, thank you, nice text.
