Research on Temperature Stress of Large-Area Concrete Beam-Slab Structure

摘要

Large-Area Concrete beam-slab Structure mainly means the monolithically cast concrete structure whose length and width are more than the maximum of the structure in the code. The influence of temperature change, shrinkage and creep on structure is the key to solving the problem. Through a practical engineering, Shrinkage and creep formulas accord with test results are brought forward. The calculation results of shrinkage strain, temperature strain and prestressed strain coincide test results and can be directed to the projects.
