| Abstract | ||||
| Concrete shrinks with time due to the evaporation of moisture in the hardened cement paste. Shrinkage develops more slowly in large members. If shrinkage strains do not develop freely due to restraints, excessive tensile stresses can develop, cause crack and then damage the durability, serviceability and long-term reliability of the structure. The purpose of this study is to present a practical analytical method of thick concrete wall considering shrinkage, thermal cracking and construction sequence. Axial stresses due to shrinkage of thick concrete wall and seasonal temperature loads are calculated using SAP2000 software and CRIRA C660 mathematical model. The CEB-FIP model is used for shrinkage calculation. A case-study for five curved walls is also represented to explain the proposed analysis procedures and applicability. | ||||
