在桥梁设计中,有些规范已经列进了对温度影响更严格的处理,即使断面不太经济,主要是因为观察到,整个桥梁的上部结构温度分布是非线性的,因此,这些规范作了关键性的改变。如果人们仔细地考虑一下,问题的实质将会容易地懂得,桥面板由于温度周期变化所发生的可能情况。桥面板底部构件,由于背着太阳射线照射,一般将或多或少与外露
Some of the specifications in bridge design have included tougher effects on temperature, even though sections are less economical, mainly because it is observed that the temperature distribution throughout the superstructure of the bridge is non-linear and therefore these specifications are critical Change. If people think about it carefully, the substance of the problem will easily understand the possible circumstances under which bridge decks will experience temperature cycles. Bridge deck bottom member, due to the backs of the sun radiation, the general will be more or less with the exposed
