摘要
随着科技的进步和经济发展的需要,桥梁建设在我国得到了飞速的发展。虽然火灾发生于桥梁的概率不大,但是每年还是有一部分桥梁发生意外火灾。本文以温度场数值模拟的基本理论为依据,采用ABAQUS有限元软件对桥箱梁进行变截面有限元实体建模,针对箱梁内火灾对连续刚构桥结构状态的影响进行了探索与研究。
With the advancement of technology and economic development,bridge construction in China has been rapidly developed.Although the probability of fire in the box-girder of bridge is small,there are still some bridge fire accidents happening every year.Based on the theory and algorithm of Heat Transfer,and by using the Finite Element method and ABAQUS finite element software,we put forward a model of box girder create varying sections.We have done exploration and research to directed or state impact of fire in box-girder to the continuous rigid frame bridge.
