Purpose & Contents
The final aim of this project is to develop a precast pedestrian bridging method that is 15% more economical than a steel pedestrian bridge, while simplifying construction and enhancing its aesthetics.

First, Development of a cross-sectional shape capable of standardizing the formwork operation with high structural efficiency, and aiming at reaching 15% cheaper construction cost than the steel pedestrian bridge by developing bridge method that can reduce labor cost and cost by minimizing site work.

Second, It is aimed at achieving the same level of construction air compared to steel pedestrian bridge by developing segment connection device and module connection device which can make the entire girder as a segment in the factory and pre-pier the pier, ramp and precast.

Third, The development of exposed concrete construction conditions applicable to pedestrian bridges, the development of standard design of sloping shrouds, and the development of standard design of piers and ramps aim at securing superior bridge aesthetics compared to steel pedestrian bridges.

- PSC exposed concrete production technology review
- Production and installation of real-scale experimental prototypes

4) Verification of modular pre-cast pedestrian bridge girder-only Structure Performance
- Performance verification test of actual scale specimen

5) Achievement of site design application performance
- Product branding, promotional brochure production and related exhibitions attending
- Standardization of design, production and construction technology
- Business promotion of ordering organization and reflecting design

Results
1) Patent application, two design registrations, one trademark registration about Modular exposed concrete precast footbridge

2) More than one Modular exposed concrete precast pedestrian bridge design, one numerical analysis specification paper, two product design specification paper

3) Prototype products about Precast pedestrian girder-only tension equipment set, real scale girder and mold form

4) Structural performance test for real scaled modular PSC-girder and connection joint of beam element

5) Product brochure, Design for footbridge could be applied at site

Expected Contribution
1. Technical expectation performance
1) By verifying the safety, construction and maintainability of the connecting part, which is the core element of the precast structure, it contributes to securing optimized connecting part manufacturing technology suitable for the prefabricated structure

2) By modular construction of construction member, overcoming limit of transportation and installation due to excessive weight, which is a disadvantage of concrete, contributing to advancement of concrete bridge and market share in the pedestrian bridge market focusing on steel bridge

3) In recent years, it has been confirmed that it can be applied to the civil engineering field of the exposed concrete method which is widely used in the construction field, and contributes to enhancement of quality management technology

4) Contributing to expansion of pre-cast technology base that can be used as a substitute for steel by modularization of piers and slopes as well as girders

2. Social and Economic ripple Impacts
1) It contributes to the enhancement of the modern image of public facilities by constructing a natural and emotional exposed concrete pedestrian bridge by escaping the poor aesthetics of ordinary concrete pedestrian bridge or the simple low-grade aesthetic of steel pedestrian bridge

2) Contributes to the reduction of national budget by spreading pre-cast pedestrian bridge which is 20% economical and low maintenance cost compared with steel pedestrian bridge

3) Reduces the need for rapid construction for minimizing the traffic cut-off time and bypass period of urban pedestrian bridge construction, contributing to the reduction of secondary social overhead costs

4) It is possible to install pedestrian bridge inexpensively in response to the demand for function-oriented pedestrian bridge establishment in elementary school, nursing home, etc.
