Concrete and steelwork well together since concrete are strong in compression, easy to produce on-site, and inexpensive, while steel is extremely strong in tension. Rather than pouring liquid concrete into a form, one first forms a mold, known as formwork that will give the concrete the desired shape and form. In the next step, the structural engineers’ drawings apply to the steel reinforcement bars, and a wire uses to tie them in place. Because it shapes like one, the tied steel calls a reinforcement cage.
The concrete needs to mix with cement, sand, stone chips, water, and a cement mixer and pour into the formwork as precisely as possible once the steel structure is in place. During a month, the concrete will reach its full strength. Because of this, it normally remains propped up until that time. A moist surface needs for this time for the chemical reactions to take place inside the concrete. While the concrete is curing, water is supplied on its surface, allowing the chemical reactions to proceed properly.
Load
As such, the structure appears to make of connected frames with solid connections between them. A moment connection is a type of connection between two members which has a strong connection between them.
Steel structures may also have hinged connections, but most concrete frame structures use moment connections. Throughout the life of a building, this frame is subject to various loads that exert pressure on it.
