Influence of Yield Strength

 

Bearing Capacity Aspect

 

Yield strength is the stress at which steel begins to produce obvious plastic deformation. In building structures, it directly determines the maximum load that the structure can bear. For example, when designing columns of a multi - storey building, if high - yield - strength steel such as Q345 steel (with a yield strength of not less than 345MPa) is selected, the columns can bear greater vertical pressure, and thus the cross - sectional size of the columns can be reduced. This is very important for space utilization. Especially in commercial buildings and other buildings with high requirements for indoor space, it can increase the usable area.

 

 

 

Structural Stability Aspect

 

When the building structure is subjected to external forces exceeding the designed load, the yield strength of the steel can provide a certain safety margin. For example, in the case of sudden overloading (such as the increase in the mass of the superstructure during an earthquake, the increase in the lateral force borne by the building during a wind disaster, etc.), if the steel has a high yield strength, the structure can still maintain a certain bearing capacity during the yielding stage, delaying the collapse time of the structure and providing the possibility for emergency measures such as personnel evacuation.

Influence of Toughness

 

Resistance to Impact and Dynamic Loads Aspect

 

Steel with good toughness can absorb and dissipate impact energy. In the case where the building structure may be subjected to unexpected impacts (such as a vehicle hitting a building, an object falling and hitting a building, etc.), toughness can prevent the steel from brittle fracture. For example, in some street - front buildings in cities, there may be a risk of being hit by out - of - control vehicles. Structural members made of high - toughness steel such as Q345 steel can absorb part of the energy during the impact, reducing the degree of structural damage and protecting the safety of people and property inside the building.

 

 

 

Seismic Performance Aspect

 

In the building structures in seismic areas, the toughness of the steel is an important factor in seismic design. During an earthquake, the ground motion causes the building to produce reciprocating deformation and vibration. Steel with good toughness (such as high - strength low - alloy structural steel) can absorb and dissipate seismic energy through its own deformation. For example, in the core - tube structure of a high - rise building, using high - toughness steel can enable the core - tube to produce a certain plastic deformation without brittle failure during an earthquake, thus ensuring the overall stability of the building and reducing the damage degree of the earthquake to the building.
