A new method of constructing open spandrel arch bridge has been developed for span ranges from 12m to 27m using precast concrete techniques. The buildability of this new system has been proven in a pilot project. It has also been proven to be an economically viable alternative to conventional bridge solution. Nonetheless, stocks of steel moulds catering for the full spectrum of span ranges have remained a costly logistic issue with many operational difficulties. The problem may become more acute especially for bridge market of relatively lower volume but with many geometrical variations. This paper presents a systematic approach to standardise the design and development process with great emphasis on the practical aspects of precasting and moulding requirements. Three sets of moulds for two types of geometrical framing, called M-Series and K-Series Open Spandrel Arch Bridge have been developed to cater for the targeted span segment. |
