Cold-formed steel (CFS) construction is widely recognised as an important contributor to sustainability and green construction. Thus, the use of CFS construction is encouraged and had been advanced by innovations in its structural applications. One such innovation that has recently gained popularity is the use of CFS sections in composite construction. The researchers assembled two CFS Clipped channels back to back to construct Ibeam sections for testing. Innovative bracket shear connectors were also developed and inserted between concrete slabs and steel beams in order to provide composite action. The composite beams were drastically stronger and stiffer than non-composite beams. The experimental results were validated theoretically with a high level of correspondence. The proposed composite beams with CFS sections were found to be strong and stiff enough to be used in the construction industry.

Roller compacted concrete (RCC) dams are attractive to many water and energy corporations around the world due to their ease in construction and low construction cost. The hydration of cement and the climatic changes on the convective boundaries are the two main heat sources for the temperature rise in the roller compacted concrete dams. Thus, changing the RCC placement schedule according to climate conditions might eliminate the problem of thermal cracks. In this research, the RCC dam method was applied in an arid region; the Bisha state in Saudi Arabia was chosen as a case study. We found that RCC dam technology can be applied safely with an alternative solution, like selecting a suitable placement schedule and reducing the placing temperature of facing at upstream and downstream sides to overcome the risk of thermal cracks.
