有无横隔板桥梁结构性能对比分析

摘要

In order to verify the validity of diaphragm in the bridge structure, we analyzed different values of stress - strain and displacement deflection through comparing static and dynamic load tests under the two cases of considering the bridge with and without diaphragm. Combined the simulation by finite element method,the results show that stress - strain and displacement are smaller when the diaphragm exists both in the static and dynamic load tests,bridge with diaphragm has more steady data and more well -proportioned transfer in loads,the validity of diaphragm is verified apparently.%为了验证横隔梁在桥梁结构当中的有效性,通过对有无横隔板两种类型的桥梁结构静动载荷试验的对比,结合有限元分析软件MIDAS进行的验证,分析在同种荷载工况作用下两种类型桥梁产生的不同应力应变和位移挠度值,结果显示有横隔梁的桥梁结构在动静荷载试验及分析中应力应变与位移挠度值都相对较小,数据更稳定,荷载传递更均匀,横隔梁在桥梁结构中有效性较为明显.
