[0002] Beam seismic design is an important part of bridge engineering design. According to the "Highway Bridge Seismic Design Detailed Rules" (JTG / TB02-01-2008) promulgated by the Ministry of Transport, all types of bridges should take seismic measures under different seismic fortification intensities. For simply supported beam (slab) bridges with discontinuous decks, measures such as blocks, bolt connections and steel clamp connections should be adopted to prevent longitudinal and transverse beam drops. For continuous beams and simply supported beam (slab) bridges with continuous decks, measures should be taken to prevent large lateral displacements. In specific practice, seismic blocks are often added on both sides of the cap beam and seismic anchor bolts are set to implement the provisions of the above-mentioned regulations.
