The total complementary energy with mixed variables of the bending of the rectangular plate is deduced by applying the reciprocal theorem in this article .It solves the problem of the bending of the rectangular plate with simply supported on four sides by applying the principles of complementary ener‐gy with mixed variables .And it gives the expression for complementary energy with mixed variables of the rectangular plate with simply support on four sides .Through calculating the deflection surface equation under different loads by this method and comparing the ANSYS value with deflection value , moment value under different loads .Finally the author verifies the method presented in this paper can be applied directly to the project .
