As elements of a metal truss are divided into several types: in most cases, triangular elements and with parallel belts are used. In addition, there are also polygon outline constructs. Despite their appearance, they are used to create large-span structures with spans of 10, 24 and 30 meters. Less common with spans of 12 and 36 meters. As for the height parameters, the polygonal ones on the support adhere to the parameter of 2.2 meters, with parallel belts - 2.5 and 3.75. These elements are used to cover the roofs of buildings with sheet metal or corrugated board. Triangular ones are designed for abssto-cement and metal-fiber coating. The choice of coverage depends on many factors and is designed individually for each building. Steel structures are used in the construction of large-scale industrial and civil facilities. The installation of rafters is carried out using welding equipment, as well as bolted connections, which ensures the creation of a light, but very reliable structure. When designing structures using these elements, the purpose of the building is taken into account. So, for civil objects (houses, shopping malls, etc.), open roof trusses are practically not used in the architecture of buildings, while for industrial ones they are often left free, since additional cladding and decor are not required in this case. Now with regard to the manufacture of metal structures . Since they are large enough, they require special equipment and an industrial site for their manufacture. An obligatory stage of production should be the control assembly of metal structures . To assemble the elements of the truss trusses, rolled steel products are used - corners, profiles, pipes, channels , etc., the choice of which depends on the design calculations and the tasks set. By assembling some structural elements directly in production, the process provides a more cost-effective approach. Расчет практически невозможно выполнить самостоятельно, потому что невозможно знать обо всех факторах, которые могут отрицательно сказаться на прочности постройки. Но есть три основных фактора, из которых исходят основные критерии расчета. Первое, что необходимо учесть – объем постоянных нагрузок; второе – дополнительных; третье – особые и периодические нагрузки и колебания. Учитывается все: от климатических до сейсмических условий, именно поэтому процедуру расчета необходимо осуществлять вместе со специалистом. Профессиональный расчет позволит не только сократить затраты на строительство, но и сведет к минимуму возможность разрушения объекта. Стропильные конструкции, пожалуй, одни из главных элементов строения, поэтому при их проектировании, изготовлении, расчете, монтаже необходимо соблюдать нормы, прописанные в СНиП.
