| Abstract: | The numerical analysis method of cracking in cast-in-place reinforced concrete slabs is presented. The results agree well with the actual conditions. The current state of knowledge and some new research findings on crack-control are introduced such as increasing the quantities of the distribution steel, adopting fiber reinforced concrete etc. Some recommended crack-control procedures used in design construction is presented based on the investigation and study of cracking in a frame structure. |
