摘要
以一座斜弯桥的静载试验为背景,采用桥梁专用有限元软件MIDAS/CIVIL建立全桥空间模型,对最不利荷载作用下的挠度值、应力值进行了计算,得出相应的理论值,并与实测值进行比较。评估其结构的安全性,计算结果表明:该桥在试验荷载作用下的最大挠度值均小于设计值和规范规定值,应力值均未超过材料的屈服强度,并具有一定的应力安全储备。
An oblique and curved bridge static load test for the background,using bridge-specific finite element software MIDAS/CIVIL space model for the whole bridge.For the most negative deflection under load,the stress values were calculated,the corresponding theoretical values obtained and compared with the measured value.Assess the safety of its structure,the results show that： the bridge under the test load deflection is less than the design values and norms are specified value,the stress value did not exceed the material＇s yield strength and stress with some safety margin.
