Frame structures are commonly used in the different industries of economy, mostly, own to theirs relatively practical structural shape which also quickens a manufacture and erection speed and provides convenient conditions at the construction site. The paper describes a new constructive shape of a steel two-pin frame which combines advantages of a light-weight of the lattice two-pin frames, with advantages of a speed manufacturing of the solid section frames. This new two-pin frame in the cornice area has a splitted cross section which the brace structure of joint is formed with. Regarding of this splitting of cross-section flexural stresses are transformed in an axial compressive and tensile forces which splitted members of cross-section are carrying. Nevertheless, there are some difficulties in defying exact forces and moment distribution between members of the frame due to increasing of the static indeterminacy of the system caused by cross-section splitting. Static structural calculations of this frame with using a superelement method were held. Analytical dependences between geometric parameters and effect of actions in the members of frame were obtained.
