摘要
采用空间梁单元和板单元的组合空间模型 ,对芜湖长江大桥正桥第三联 3× 1 44 m板桁结合连续钢桁梁施工过程中主桁杆件和桥面板的应力变化及结构的自振特性进行了较为详细的分析。
With space models composed of space beam elements and plate elements,not only the variations of stresses in truss bars and in decks of bridge for 3×144m continuous plate truss composite steel truss bridge across the Wuhu Changjiang River in constructions are calculated,but also the space natural vibration properties for this bridge analyzed in detail.
