- ANALYTICAL STUDY ON BENDING PROPERTIES OF BEAMS WITH BOTH ENDS FIXED CONSIDERING THE EFFECT OF DRYING SHRINKAGE
抄録
<p>In this study, we used FEM software that enables creep deformation analysis and elasto-plastic analysis when a linear spring is installed at both ends of the beam to restrain it in the axial direction, and drying shrinkage strain is applied while applying a vertical load. Long-term properties were evaluated. Furthermore, in order to clarify short-term properties such as during earthquake motion, Pushover analysis was performed after long-term analysis. As a result, the following findings were obtained.</p><p>1) Long-term analysis showed that axial force was generated in beams when cracks did not occur due to drying shrinkage, but axial force decreased when cracks did not occur. In addition, when cracks occurred, the stress of the main reinforcement on the tension side at the end of the beam increased as the degree of beam restraint increased or as the drying shrinkage strain increased.</p><p>2) As a result of short-term analysis, the bending strength of the products with drying shrinkage was almost the same as those without restraint, and the products with no cracks were almost the same as those without restraint. However, when cracks occur, the bending strength is greatly reduced. However, bending stiffness decreased in all models.</p>
