小半径宽箱弯梁桥梁格计算方法对比分析

Comparison and Study on Grillage Analysis Method of Wide-box Girder with Small Radius Circular Curve

以某4x30m小半径宽箱室连续弯梁为工程背景,根据汉勃利梁格和慧加梁格理论,分别利用MIDAS CIVIL以及WISEPLUS有限元软件建立梁格模型,对比分析了同一荷载工况下两模型的支反力情况,并建立实体模型进行验证.分析发现:慧加梁格理论可以更好的适用于宽箱弯梁的工程设计分析.

Based on a 4＊30 m ranged wide-box girder with small radius , according to Hambly grillage method and Wiseplus grillage method , two grillage models were established respectively with MIDAS CIVIL and WISEPLUS finite element program .The reactions under the same load condition were analyzed by comparing the two models .Additionally , a solid model was established to verify the results .The analysis shows that the Wise-plus grillage method is more applicable for the engineering design of wide -box girder with small radius .
