First of all, answer the question: No! It is not better to have more steel bars when building a house.

As the economic level of countries continues to rise, cities are expanding and taller buildings are being built. But many people have a big misconception when building houses, that the more steel the stronger the house. This article allows Baowu to take you through why the more steel the stronger the house will be a misconception.

First of all, people who do engineering know that the main purpose of steel is to withstand tension rather than pressure, the pressure is the concrete, the combination of steel and concrete can be both tensile and compressive, so as long as the proportion of steel and concrete to a certain extent, that is, the reinforcement rate is suitable, it can play a very good effect. If you increase the rebar, it is a complete economic waste, no sense.

Secondly, if too much reinforcement is put in, there is no obvious deformation when it is destroyed. Damage can only occur in concrete and reinforcement at the same time if the reinforcement ratio is appropriate. Putting too much reinforcement will increase the bearing capacity, resulting in the concrete being crushed first, while the reinforcement does not reach the force limit value, and the damage will not be obvious enough to alert people to stop using the dangerous building, which may cause casualties once the reinforcement is damaged. Once the damage occurs, people will anticipate the accident and they can evacuate in time without causing casualties.

But if too much steel is used when building a house, once damage occurs, the member is directly brittle fracture, people simply have no reaction time, the danger is very high.

Because of the above-mentioned reasons, it is not good to put too much rebar when building a house. If you put too much rebar, not only will it be a waste of money, but it will also bring some safety problems.

So, do you understand? When building a house must pay attention, calculate the reinforcement rate of steel and concrete, and then build the house.
