Problems and Suggestions of Chinese Highway Bridge Seismic Design
The seismic design of Chinese Highway Bridge changed from single standard of fortification and one-step design performed nearly two decades to two-level fortification and two-stage design with the introduction of the new codes in 2008 and 2011. However, there are some shortcomings of the new codes such as the choice of response spectrum type, the determination of reinforced concrete constitutive relation, the discrimination of site-type and the bearing checking items, which leave a large room for improvement. Combined with the design codes of the developed countries like Japan and the United States, some useful suggestions are put forward in this paper for Chinese existing design codes. It is believed that Chinese seismic levels can be significantly increased so long as highway bridges are designed in accordance with the improved codes.
