| Abstract: | An example of cracking on the lower surface of reinforced concrete roof-plate is presented. Based on finite element analysis, a conclusion is made that those cracks are caused by large asymmetry subside of the frame's columns. Then the way to calculate the width of such cracks is raised. The design method for the reparation that can prevent the cracks from widening by sticking steel plate to the critical members is also developed. This method is applicable in realistic work. |
