Abstract：Transforming existing straight segment of high rank road into airstrip for urgency is one effective means to maintain wartime airlift safeguard capacity, but rise and fall of plane would be affected by middle and small-span bridges of straight segment of high rank roads. In this thesis, standard multi-span simple-bracket 13-meter-span preparatory stress bridges are researched which widely exist in present high rank roads. The initial status of preparatory stress bridge is analyzed with LS-DYNA. The strike response of bridges by plane landing is also analyzed by the same means. Hereby, bearing capacity of bridges with 13 or 10 meter span are calculated when planes directly land. The result indicates that 13-meter-span bridges are comparatively risky to support direct landing of some plane. The relevant conclusions can be references for choosing emergent plane runway among straight segments of high rank roads in future.
