摘要
依托某42.5+65+42.5m三孔一联变高度预应力混凝土连续箱梁桥,用midas civil建立有限元模型,在E1、E2地震作用下对该桥的墩柱进行了抗震分析。分析结果表明,该墩柱达到了抗震设防目标。
A fin ite element model was b u ilt by midas c iv il based on a continuous prestressed concrete boxgirderthree holes bridge, the span of which is 42.5m＋65m＋42.5m. We carried out seismic analysis of piercolumn of the above bridge under E l and E2 earthquake actions using the b u ilt model. The resultsshowed that the pier reached the goal of seismic fortification.
