Commercial and High Rise Building Beam Design

Beam Design and Structural Design in Commercial and High-Rise Buildings

Beam design and structural design in high-rise buildings is constantly evolving. Structural designs are created to withstand earthquakes and high winds, conform to building codes, and construct impressive visual designs. Beam designs can significantly affect the stability of a high-rise building as well as the aesthetic appeal of a structure.

The structural design of a high-rise building is greatly dependent upon lateral loads. For this reason, bean design in high-rise buildings deserves careful consideration. Specially designed internal support system help keep the structure stable, especially in high wind and during earthquake tremors.

Factors Affecting Beam Design and Structural Design in Commercial and High-Rise Buildings: Drift and Acceleration

Another factor that plays into the beam design and structural design of commercial and high-rise buildings is drift. Drift is defined as the ratio of the building deflection over its height. Structural engineers must also take into consideration building acceleration when designing beams for commercial and high-rise buildings. Building acceleration is a measure of the speed with which drift occurs. This plays a critical role in the stability of a high-rise structure.

Beam Design in Commercial and High-Rise Buildings: Shear Wall Systems

One popular way to stabilize a high-rise building is by using shear wall construction. A shear wall is designed to withstand the combined forces of shear, moment, and axial loads caused by wind loads and gravity loads in a high-rise building.  A shear wall system joins solid structures that remain constant from floor to floor to add strength and stability in a tall building. However, shear wall construction inhibits the design of the foyer or lobby of a building. To achieve an open, inviting space, structural engineers often must use a combination of other support systems to allow for the desired design of the building.

Transfer beams are often used in conjunction with a shear wall system in commercial and high-rise buildings. Transfer beams are designed to transfer the load from the shear walls to the lower frame of the structure. This combination of transfer beams and shear wall supports has proven reliable, even in high winds and during an earthquake.

Beam design and structural design in commercial and high-rise buildings can utilize many different design techniques to achieve the desired height and visual attractiveness specified by the architect and owner. Beam design and structural design in commercial and high-rise buildings is an ever-evolving process.
