Solutions for reinforcing steel structures of industrial plants without using welded bonding

In this paper, the authors present solutions to reinforce steel structures of industrial plants to make them eligible to install solar cells on roofs without using welded bonding. All solutions offered use bolt links which are suitable for fire protection requirements and result in fast construction and less disturbance to the factory's production. The solutions also take into account the feasibility of the construction work in accordance with the factory equipment system and the ceiling, as well as the aesthetics of the reinforcement building. In addition, the method of estimating the hanging load from purlin deflection and the calculation method of the reinforcement structure in two stages are also provided.
