边跨不设合拢段时连续箱梁桥的温度效应研究

he construction method of setting without closing segment on side span of long continuous box-girder bridge has been widely used and is influenced by temperature tremendously. In order to understand temperature effect on the role of this construction method .Taking side span closure of a continuous box-girder bridge in Wuhan as example. It introduces applying the finite element analysis software ANSYS to simulate nonlinear temperature field of ∏ structure box-girder and analyses deflection and stress result of ∏ structure under the effect of temperature. It also researches the method to eliminate the effect of temperature and proves the mobility of construction method of setting without closing segment on side span.
