摘要
早龄期混凝土的力学性质随时间而变化,混凝土结构的温度应力随着温度、时间、约束等条件的变化而变化,其徐变度也是加荷龄期τ和持荷时间t的函数。借助通用有限元软件ANSYS,将初应力法应用于求解混凝土结构的温度徐变应力中,并通过实例验证该理论分析可以应用于工程实际。
The mechanicalproperties of early age concrete varies with time,and temperaturestress also varies with temperature,time,and restriction.The creep degree is a function of Load-ApplyingTime(τ)and Load-DuringTime(t).With the general finite element software ANSYS,the temperature stress of concrete structure can be solved using the Initial Stress Method.This theoretical analysis has been verified by the Electric PowerDispatchingBuildingproject,and is proved to be practical.[
