| Research Abstract |
In the investigation on the shrinkage cracks of concrete, the tensile stress and tensile creep strain measured in concrete specimens with and without deformed bar showed different tendencies and the influence of time-dependency in bond behavior between concrete and deformed bar was clarified. By conducting the finite element analysis of underground RC structure-soil system, the active soil pressure reduction due to creep deformation of side wall and the possibility of reduction of wall thickness and reinforcement amount were clarified, which may lead to the rational design of underground RC structures. Furthermore, the influence of sustained shear and compression forces on the deformation of joint connection with stud shear connector in steel-concrete hybrid structures was quantitatively clarified.
