The study focuses on the structural design and detailing of steel joints for an industrial mixer plant in accordance with guidelines provided by the American Institute of Steel Construction, incorporating provisions from AISC 360 and relevant design guides to ensure safe and efficient performance under demanding industrial conditions. Industrial mixer plants are subjected to complex loading scenarios that include not only conventional dead and live loads but also significant dynamic forces arising from rotating equipment, vibration effects, and cyclic stresses that may lead to fatigue over time. This work addresses these challenges by presenting a comprehensive approach to the design of various types of steel connections, including bolted, welded, shear, moment-resisting, and base plate connections, ensuring that each connection type satisfies strength and stability requirements while also meeting serviceability criteria such as deflection control and vibration resistance. Special emphasis is placed on the behavior of joints under repeated loading conditions, highlighting the need for fatigue-resistant design and the selection of appropriate connection configurations such as slip-critical bolting where necessary. In addition, the study underscores the importance of proper detailing practices, including adequate spacing, edge distances, weld quality, and constructability considerations, to facilitate ease of fabrication and erection. Overall, the design methodology aims to achieve structural safety, durability, and long-term operational reliability, ensuring that steel joints perform effectively throughout the service life of the industrial mixer plant under both static
