Paper Title:
Numerical Analysis of Reasonable Hinge Joints Size of Reinforced Concrete Hinged Plates
  Abstract

In order to study the stress distribution in hinge joints of different depth and the effects of hinged plate by hinge joints depth, 5 group ANSYS finite element models of concrete simply supported hinged plates were built, hinge joints stress of models have been compared under the center load and side load, analysis has been made on the hinge joints of maximal stress. The analysis results indicated that with the increase of the depth of hinge joints, the transverse tensile stress, vertical shear stress and longitudinal tension stress were all showed regular distributions, and with the increase of the depth of hinge joints from 10cm to 26cm, the maximum reduction value of transverse tensile stress in hinge joints was 3.25MPa, the reduction range was 51.9%; the maximum reduction value of vertical shear stress was 1.06MPa, the reduction range was 77.9%; longitudinal compressive stress decreased gradually, and longitudinal tensile stress increased; the maximum reduction value of hinged plates deflection difference was 0.16mm, the reduction range was 36.4%; the transverse tensile stress of hinged plates’ bottom increased. Therefore, increasing the depth of hinge joints was the most effective way to increase the transverse stiffness of slab girder and to prevent hinge joints damage. At the same time, the tensile reinforcements setting in transverse and longitudinal at the bottom of hinge joints and the tensile reinforcements setting in transverse at the bottom of slab girder should be strengthened.
