LONG-TERM FINITE ELEMENT ANALYSIS OF DEFORMATION BEHAVIOR CAUSED BY DRYING SHRINKAGE IN FRAME MODELS ASSUNMING A RIGID-FRAME STRUCTURES

In reinforced concrete structures, drying shrinkage strain and creep deformation occur continuously over a long period of time. When concrete members are anchored to other structural members, stresses are generated and cracks may occur, adversely affecting the serviceability and durability of the structure. In this study, some examples of continuous frame models assuming reinforced concrete rigid-frame structures were created, and elastoplastic analyses were conducted over a long period of time by applying drying shrinkage strain and applying the FEM analysis software that simulates creep analysis to evaluate the damage that occurs in the entire structures, and to evaluate the damage that occurs in the entire structures. The objective of the study was to evaluate the extent of the restraining spring against the tensile axial force of the beams proposed in previous research. The following results were obtained.
