| Abstract: | On the basis of theoretical analysis about generation and development of crack on floorboard,its generating mechanism under the action of racking load,such as temperature,shrinkage and creep,is interpreted with a fault case.The internal forces caused by the action of racking load,which is calculated,are the same as the results of the actual measurement.In the end,some conclusions and propositions about the control and design of crack are presented. |
