000010727 520__ $$2eng$$aIn China，the seismic design of highway bridges must comply with <Specifications of Earthquake Resistant Design for Highway Engineering JTJ004-89> (1989) since 1990, which is valid only for bridges with the main span shorter than 150m. The spatial effects between seismic excitations acting on different piers, such as the wave passage effect or the incoherence effect, were not mentioned, and only the response spectrum Method and the time history scheme were specified for seismic analysis, with the power spectrum method excluded. The above < Specifications 1989> (its bridges part) will soon be updated by <Specifications of Earthquake Resistant Design for Highway Bridges>, published in September, 2008. In this <Specifications 2008>, some issues about this alternation will be described. In <Specifications 2008>, design principles are given for highway bridges with net-span longer than 150m. Therefore, the seismic spatial effects should be taken into account for such bridges. The random vibration based power spectrum method (PSM) is added as an optional means for structural seismic analysis. As the Pseudo Excitation Method (PEM) developed in China has been widely accepted as an accurate and efficient algorithm of PSM, some details about PEM are also involved in <Specifications 2008> and will be explained in this paper.
