利用ANSYS的钢管混凝土拱梁组合桥分析

Analysis onArch-girder Combination Bridge with Concrete-filled Steel tube with ANSYS

为研究钢管混凝土拱梁组合桥的受力形态,运用ANSYS软件对某一钢管混凝土拱梁组合桥分别建立了全桥整体模型、主拱局部模型以及主拱屈曲模型。计算了主梁及主拱受力,验算了主拱连接钢缀板及钢锚箱应力,进行了主拱屈曲分析。结果表明,桥梁受力满足规范要求,结构安全可靠,主拱不会发生失稳现象。

To study the mechanical character of the arch-girder combination bridge with concrete-filled steel tube,including the overall bridge model,the partial model of arch and bending model of arch,finite-element hree finite element models are built for this type bridgeintroduced This paper introducted the mechanical behaviors of girder and arch,connectedthe stress of the steel connect slab and steel anchor box,and analyzed the buckling of arch.the bridge satisfiedspecifications,e strength of bridge satisfy the s cifications and the structure is safe.The instability of the arch will not happen.
