The use of cold-formed steel bearing elements in structures requires consideration of some different rules in addition to the sizing rules of traditional steel structures, as the behavior of all elements under resistance and the physical moments of collapse are quite different from those of the hot rolled heavy steel bearing elements. In addition, the profile shapes of the elements used, the joining tools and their use in the building are different from those of conventional steel structures in many areas. For this reason, current steel structure standards do not include this type of structure.
The Cold-formed industry team has developed special design calculation aspects by conducting research and development studies with valid load standards based on the regulations prepared by many countries, especially in Europe, and develops the results of the studies, international investigations and finite element results. In addition to the conventional design methods of conventional steel in cold-formed industry production processes, the experience gained with R&D and P&D is taken into account.
National and international publications on this subject are always being researched. Cold-formed industry design methods make up-to-date changes by taking the results as reference.
Cold-formed industry is based on the conditions given in TSEN 1991-1-3 for snow loads defined in TS 498 international standards, excluding snow, wind, earthquake, design load values taken during the design phase. Wind loads take the values given in TS EN 1991-1-4. It takes earthquake code conditions for earthquake effects. Load combinations that will create characteristic resistance for strengths are selected and depending on Usability, ensuring that the structure fulfills what is expected under the foreseen conditions of use, ensuring its resistance to environmental effects and not being affected by non-structural elements, ensuring physical conditions, Usability conditions are determined by the change of the resistance principles system and all energy limits such as acceleration. conditions are operated completely independently of other strength conditions.
