| Abstract: | Ultimate capacity of unstiffened cover-slab of tubular structure using in the supporting joint is researched.The mechanical principle of the unstiffened cover-slab is discussed,and the mechanical models are established.Based on the model,the formulas of bearing capacity are recommended.According to the results of finite element analysis of 100 models which vary with the geometrical parameters,two handy tables of the factors in the bearing capacity formulas are established.And the applying method of the tabl... |
