Introduction

The implementation of the course project "Framework of a one-story industrial building" in the discipline "Metal structures" is aimed at assimilating the knowledge gained in studying the theoretical part of this discipline and at developing practical skills for calculating and designing metal structures.

In the course design, the features of the placement of structural elements of the frame in plan and height, the diagrams of the links between the columns, horizontal and vertical links on the coating, the layout of the transverse frame, the rules for determining the values ​ ​ and the nature of the various loads acting on the frame - constant, temporary - are considered.

Calculation of steel structures is carried out according to the method of limit states in accordance with the provisions of SNiP II2381 * "Steel structures" and according to SNiP 2.01.0785 "Loads and impacts."
