Abstract: According to the elastic theory of flat slab supported by columns, two values of α_c, the ratio coefficient of bend moment within the width of column strip under "American rule" and "Chinese rule" are worked out. Afterwards, a referenced value of the width of column strip, B_cand α_c are proposed based on the two rules, which offers a reference to revising regulations and designing the construction projects.
