钢-混凝土组合梁体系转换新技术

Steel-Concrete Composite Beam System Transform Technology

钢 -混凝土组合梁是由钢结构通过剪力钉与混凝土共同作用所形成的组合结构 ,其内力在形成过程中不断变化 .以深圳丽水桥为背景工程 ,利用截面与内力均在变化的特殊性 ,在适当阶段对结构进行体系转换 ,可以调整结构内力状态 ,获得经济效益 。

Steel concrete composite beam is formed of steel structure joined with concrete by shearing key. Its inner force is changing during all the process. As the background project of shenzhen bridge utilizing the specificity of synthesis change of inner force and section, doing system transform at proper stage, it can adjust the station of inner force, gain economic benefit, having a good using future.
