| Abstract: | In this paper, the surface equation of a Four Pitch Rectangular Roof is established by means
of generalized function-sign function and inclined coordinates. And then the internal force
formula for the Four Pitch Rectangular Roof simply supported around is derived from the elastic shell theory and variational method. |
