This paper reckons the standard formula of contraflexure point under the load of inverse-triangle. The auther checked the standard height formulas of contraflexure point under the concentrate load at the zenith, uniform load and the load of inverse-triangle. The modification equations are checked when both of the rigidity per unit length of upper and under beams different, and the rigidity per unit length of upper and under columns different. Fi- nally he works out Excel tables and has validated the correctness of these tables when using the tables calculate the actual project.
