All concrete structures are exposed to volume changes caused by hydration reactions in the early age. if the volume changes are restrained, stresses is generated which will cause cracking when it overcomes the tensile strength. as the mechanical properties of early age concrete vary with time, especially the creep degree depends on the time elapsed and the time at loading, to calculate the stress of concrete structure is a complex nonlinear problem. the finite element method ( fem ) can take account of the evolution of the stiffness properties, the development of thermal strain, creep, shrinkage and so on. in this paper, a general approach for numerically simulating this type of behaviour is presented firstly. then, how to solve this problem is introduced by the general finite element software ansys using the initial stress method. finally, a detailed description of an example calculation that demonstrates the potential of the numerical simulation strategy follows
早期混凝土由於水化反應都會產生體積變化.如果體積變形受到約束就會產生應力，一旦超過混凝土的抗拉強度就會產生裂縫.由於早期混凝土的力學性能是隨時間變化的，特別是徐變，它不僅與加載時間有關而且同時隨齡期而變化，因此計算早期混凝土結構應力是較為復雜的問題.有限單元法不僅可以考慮混凝土剛度的變化，而且可以考慮溫度、徐變、收縮等因素.本文利用初應力法對通用有限元軟體ansys進行了二次開發，通過工程實例計算了高層建築地下室側墻早期混凝土應力的變化過程，並提出了相應的抗裂措施 -
