| 该结构为200cm×20cm×20cm的混凝土梁，所处的环境湿度RH=70%，C50混凝土,混凝土收缩开始时间为3d；施工阶段划分为：混凝土浇筑完成后前60d混凝土梁一端固结一端自由，即静定状态；混凝土浇筑完成60d后，混凝土梁边界约束条件变为两端固结，结构由静定转化为超静定。 |

| The size of the concrete beam of C50 class of concrete is 200cm × 20cm × 20cm. The relative humidity (RH) is 70%. The starting time for concrete shrinkage is the third day. After the completion of the concrete pouring, the construction is divided into two stages: the first stage in within 60 days in which concrete beams are in statically indeterminate state by consolidation of one end of the beams while the other end being free; the second stage is beyond 60 days (after the completion of the concrete pouring) in which concrete beams are in statically super-indeterminate state by consolidation of both end of the beams. |

如果是“混凝土收缩开始时间为第三天” A beam, made of C50 concrete, the structural size of whom is 200cm×20cm×20cm and the environment humidity RH 70%, begins contracting from 3th day. Starting from the moment when its pouring is finished, the beam transforms from the initial statically determinate structure with one end is constrained and the other freedom, formed during the first 60 days after pouring, to statically indeterminate one with both ends constrained, formed from the 60th day after pouring. 如果是“混凝土收缩时间为三天” A beam, made of C50 concrete, the structural size of whom is 200cm×20cm×20cm and the environment humidity RH 70%, will finish contracting within 3 days. Starting from the moment when its pouring is finished, the beam transforms from the initial statically determinate structure with one end is constrained and the other freedom, formed during the first 60 days after pouring, to statically indeterminate one with both ends constrained, formed from the 60th day after pouring. |

应该是这样的: 如果是“混凝土收缩开始时间为第三天” A beam, made of C50 concrete, the structural size of whom is 200cm×20cm×20cm and the environment humidity RH 70%, begins contracting from 3th day. Starting from the moment when its pouring is finished, the beam transforms from the initial statically determinate structure with one end constrained and the other freedom, formed during the first 60 days after pouring, to statically indeterminate one with both ends constrained, formed from the 60th day after pouring. 如果是“混凝土收缩时间为三天” A beam, made of C50 concrete, the structural size of whom is 200cm×20cm×20cm and the environment humidity RH 70%, will finish contracting within 3 days. Starting from the moment when its pouring is finished, the beam transforms from the initial statically determinate structure with one end constrained and the other freedom, formed during the first 60 days after pouring, to statically indeterminate one with both ends constrained, formed from the 60th day after pouring. |
