介绍了钢桁架与混凝土组合梁的三维空间分析系统 ,对芜湖长江大桥主桥的主梁即采用钢桁架与混凝土组合梁作详尽的空间有限元计算分析 ,得到了组合梁的交接面滑移、竖向掀起位移沿梁长分布及刚度变化对其影响的图形 ,并详尽地分析了交接面滑移、竖向掀起位移沿梁长分布规律、连接件受力性能及交接面的连接程度对组合梁的刚度影响 ,为钢桁架与混凝土组合梁的设计提供可靠的理论依据·
The three-dimensional space analysis system of steel truss and concrete composite beam is introduced. The main girder of the main bridge of Wuhu Changjiang River Bridge is analyzed by using the steel truss and concrete composite beam in detail. The interface slip, Vertical displacement along the beam along the length of the distribution and the impact of changes in the stiffness of the graphics and detailed analysis of the interface slip, vertical displacement along the beam length distribution, the connector performance and interface of the connection degree of the combination The stiffness of the beam, providing a reliable theoretical basis for the design of steel truss and concrete composite beams ·
