Do self-built American villas choose reinforced concrete structure or steel structure?

Since the concept of green building was put forward, the environmental protection and energy saving of buildings have attracted more and more attention. With the continuous development and innovation of building materials, the choice of building materials for house construction has become more and more abundant. Among them, the American-style steel structure villa with steel as the main material has become a dark horse in the development of green buildings in recent years. With the increasing popularity of green buildings, is it better to choose reinforced concrete structures for self-built American villas? Or is the steel structure better?

Based on the building materials used in traditional reinforced concrete villas, except for the steel bars, which are reusable building materials, the remaining building materials such as cement, sand, and red bricks cannot be recycled. Pollution. More data show that because the complete drying time of concrete generally takes 40 years, it is easy to increase the indoor humidity, which is not conducive to human health. The steel structure villa has a low impact on the environment, whether it is the construction process or the demolition, because the steel is used as a recyclable building material, and the construction method is dry construction. In addition to the need for concrete for infrastructure construction, the wall and roof materials are made of environmentally friendly materials without concrete, which eliminates the potential damage to human health that the concrete is not dry completely.

People are more familiar with the construction process of concrete villas, and generally feel that reinforced concrete buildings are stronger and more durable than steel structure buildings that are connected together with screws. But steel engineers have pointed out that when an earthquake strikes, houses made of reinforced concrete tend to collapse more easily than those made of steel. Because the seismic activity is up and down and left and right, steel itself has high ductility that concrete does not have. This feature can reduce the seismic response of steel structure houses, and the steel structure can absorb and consume seismic input through the plastic deformation of the structure, thereby improving the seismic performance of the house. Therefore, concrete houses with better compressive capacity actually do not have steel structures. The house is so earthquake resistant.

With the further deepening of people’s understanding of American steel structure villas, the advantages of steel structure such as light weight, high construction efficiency and economic efficiency will be discovered and recognized by people one by one. Steel structure villa will become the first choice for self-built villas. rather than the current consideration option.
