【 摘 要 】

A rapid growth of development in our country has demanded our road network to be expanded over the last few decades. To cope with rapid development, the transport industry has deployed larger vehicles with heavier axle loads. In many instances, the level of services of our road network governed by the bridge load capacity. Since pre-independence era, our bridges have been designed based on the British Code. Begin with British developed code of DSIR at early 20s to British Code (BS) and eventually to Eurocode, our bridge loadings have been evolved substantially. In the midst of foreign code, our National Axle Load study conducted in mid 80s has also marked a significant finding to our local bridge capacity in which three major groups of load carrying capacity have emerged from namely STAL, MTAL and LTAL. This paper presents the journey of our local bridge loading code of practice and the corresponding impact to the structural design and construction. Comparisons are made as early as in 20s at the time where the code was based on British Department of Scientific and Industrial Research (DSIR) to the early age of British Code and to the migration of Eurocode. A typical concrete bridge deck spanning of 20m to 60m are modeled and analyzed with respective live loading derived from these established code of practice. Discussion on the way forward of implementing the Eurocode into our local design practices are also included.
