| Abstract: | When two direction slab under different support condition along four side and different ratio of wide to long broken down , the paper analyzed that the support condition and ratio of wide to long how to influence plastic broken line . Supposing slab pieces divided by plastic broken line is absolutely rigid body. Using limit equilibrium equation of rigid body and virtual work principle , the formulas of plastic internal force of two direction slab will be inferred. |
