Footbridges are needed where there is a separate pathway must be supplied for human beings to move site visitors flows or some physical impediment, along with a river. The masses they convey are, with regards to toll road or railway bridges, pretty modest, and in most circumstances a reasonably light structure is needed. They are, but, often required to give a protracted clear span, and stiffness then becomes an crucial consideration. The bridges are frequently required very virtually on view to the general public and consequently the advent deserves careful attention. Steel of ers financial and appealing kinds of creation which suit all of the requirements demanded of a footbridge. Due to fast creation of a massive quantity of foot over bridges, many existing bridges placed in seismic zones are poor to face up to earthquakes. In order fulfil the requirement of this improved visitors in the limited land the length of bridge will become medium to large. During an earthquake, failure of shape starts at factors of weak spot. Generally, weak spot is due to geometry, mass discontinuity and stiffness of shape. In this undertaking we can layout for a most appropriate foot over bridge together with connection details and additionally estimation of structural components at the side of foundation detailing for the foot over bridge structure.
Introduction
I. INTRODUCTION
The steel areas required ought to be accessible in principle asset focuses - The segments are probably going to be more uniform fit as a fiddle and size than timber segments, permitting clear development of standard truss plans - Joints are less demanding to make than in timber trusses . It ought to be conceivable to develop a standard outline in a medium measured workshop in advantageous estimated parts for transport to site. Get together on location includes darting the parts together and fitting a timber deck, errands that can be done under supervision of a capable expert by neighbourhood craftsmen and others talented in utilizing their hands. Synthesis of quantitative and qualitative evidence for accident analysis in risk based highway planning, states the quantitative and qualitative evidence for the accident analysis road space is a scarce resource so accumulation of future volume traffic is taken into account. The forecasting for the future volume traffic is calculated and appropriate junctions are provided. Physical method of traffic control, states the designing and control of signals at the various junctions on the basis of traffic flow and time period for the particular junction. Signal control at intersections, states the different methods of signal design and provides information about trial cycle method in which traffic volume count for every 15 minutes is taken into consideration for each junction. Road safety management using Weight-age analysis, states the method of weight-age analysis in which accident severity index is calculated and design criteria is decided based on the accident cost ratio.
II. SCOPE
Foot-over bridge for most critical junction.
Estimation of structural component of foot-over Bridge.
This project includes accident analysis and design of each junction.
Traffic forecasting for future ten years with sign.
III. METHODOLOGY
The target of this venture is to outline a Foot over scaffold , alongside association &foundation points of interest, and to dissect it, beneath said fundamental parameters are considered:
Broad writing review by alluding books, specialized papers did to comprehend essential idea of subject.
Selection of a suitable model of foot over scaffold.
Computation of burdens and choice of preparatory cross-segments of different auxiliary individuals.
Geometrical demonstrating and basic investigation of foot over scaffold for different stacking conditions according to IS Codal arrangements.
Interpretation of results. Following exploration must be completed for meeting the above destinations:
Now foot over bridge are demonstrated and investigated as a three dimensional structure utilizing STADD.Pro V8
STAAD pro highlights cutting edge UI, perception devices, capable investigation and plan motors with cutting edge limited component (FEM) and dynamic examination abilities. From show era, investigation and configuration to representation and result confirmation STAAD genius is the expert first decision. STAAD expert was created by rehearsing engineers far and wide. It has advanced more than 20 years and meets the necessities of ISO 9001 confirmation. STAAD or (STAAD.Pro) is an auxiliary investigation and outline PC program initially created by Research Engineers International at Yorba Linda, CA in year 1997. In late 2005, Research Engineers International was purchased a more established adaptation called STAAD-III for windows is utilized by Iowa State University for instructive purposes for common and basic specialists. At first it was utilized for DOS-Window framework. The business form STAAD Pro is a standout amongst the most generally utilized basic investigation and outline programming. It underpins a few steel, cement and timber configuration codes.
IV. LITERATURE REVIEW
Synthesis of quantitative and qualitative evidence for accident analysis in risk based highway planning, states the quantitative and qualitative evidence for the accident analysis road space is a scarce resource so accumulation of future volume traffic is taken into account. The forecasting for the future volume traffic is calculated and appropriate junctions are provided.
Physical method of traffic control, states the designing and control of signals at the various junctions on the basis of traffic flow and time period for the particular junction.
Signal control at intersections, states the different methods of signal design and provides information about trial cycle method in which traffic volume count for every 15 minutes is taken into consideration for each junction.
Road safety management using Weight-age analysis, states the method of weight-age analysis in which accident severity index is calculated and design criteria is decided based on the accident cost ratio.
A. Necessity
People are unaware about traffic at junctions.
While crossing the road this may lead to loss of life or injury, in order to reduce this effect there is a necessity for foot over bridge at most critical junctions:
Regulation of the traffic flow and time delay.
Reducing the number of accidents.
Long sight clearance distance.
Conclusion
In the present era, technology in construction is growing at a rapid phase which require adequate knowledge in construction and designing for foot over bridge means like structural components of foot over bridge, columns, beams, loadings on foot over bridge etc. So there is need for proper estimation while designing and analysing the foot over bridge. If we could optimize the design of foot over bridge and use more resources, it will save a lot of money and resources. In olden day’s angle sections are used in making of truss in structure of foot over bridge, currently tubular sections are preferred as they are more economical.
The wind load acting on foot over bridge will be comparatively less in magnitude as it is open structure with more openings, but failure of the towers is mainly due to High Intensity Winds and Earthquakes. So high factor of safety should be given to wind loads and seismic loads.
