摘要
结合现有实际工程,利用MIDAS有限元软件建立了针对轨道交通简支梁的单梁模型与梁格有限元模型。结果表明:2种有限元计算模型各有优缺点,划分梁格可以较为准确地模拟混凝土箱梁桥的整体力学行为,获得更细致的计算结果。
Combined with the existing practical engineering,the single beam model and grillage finite element model of simply supported rail transit beam were established by MIDAS finite element software.The results showed that:the two finite element calculation models had their own advantages and disadvantages,could more accurately simulate the overall mechanical behavior of concrete box girder bridge by dividing the beam lattice,and obtain more detailed calculation results.
