The measure of industrial development; Per capita consumption of steel profiles used in steel structures is accepted. The ability to pass through large span structures and to rearrange the structures at any time depending on the need, the ease of disassembly has led to the use of steel structures in industrial buildings without an alternative. In addition, the fact that it is the most earthquake resistant structure with its light mass in earthquake zones has made it necessary to build a steel structure. In industrial buildings, besides the machine and facility costs, steel structures with very low costs will protect these facilities in the safest way against earthquakes and will be the most important earthquake insurance. Main Reasons Why Steel Construction Costs Are Higher Than Other Alternatives: The fact that not every cross-section of IPE, H-type economic long profiles can be found, and the use of larger cross-sections increases the construction costs. Project and manufacturing costs are high. In the computer environment; The use of integrated projecting and production technique from the project to CNC manufacturing. Lack of qualified personnel experienced in steel structures in the process from project to manufacturing and assembly in steel structures. STA-STEEL calculates the industrial accumulation of developed industrial countries in the most accurate and precise way by using all kinds of modules of finite elements, even the most difficult details. In structural analysis, advanced analysis techniques will be applied by considering 3 dimensional finite elements in all offset misalignments. Performing all cross-section and detail calculations with finite elements that give the most accurate results will reduce the additional costs of excessive security in the approximation calculations, and will provide advantages to the building economy. The most suitable cross-section and details can be selected with the optimizations that provide the most optimum calculation of building costs. On steel structure modeling techniques; It will develop the projecters by making economical design and ergonomic building planning.
