Description
The cross frame of the forge-press shop with light and medium-mode cranes with a span of 30 m, equipped with two bridge cranes with a lifting capacity of 100 t of the 7K operating mode, was designed. The length of the building is 120 m, the elevation of the rail head is 13.5 m. The pitch of the trusses and columns is 6 m. The place of construction is Mogilev. Single-span building with rigid conjugation of crossbar with columns. The girder is designed in the form of a rafter trapezoidal truss with a height of 3150 mm and a roof slope of 1/12. For all designs C275 steel in accordance with GOST 27772-88 is accepted.

2 Cross Frame Design and Calculation
2.1 Development of communication system
The links ensure spatial immutability of the frame, stability of the compressed elements of the supporting frame and joint work of all structures. Communications perceive and transmit braking and wind effects on the foundation, provide the necessary installation conditions for the structure elements.
