Planning of an Earthquake Resistant Steel-Beton Composite Building According to the 2010 Earthquake Map

Introduction

The development of construction technology has brought about a significant shift in the world of architecture, with a growing trend towards the use of steel as a primary material. This is not only due to its high strength, but also because the use of steel can reduce construction waste, making it a more environmentally friendly option. One structural design method that leverages the superiority of steel is the composite system, which combines steel and concrete to produce a strong, durable, and cost-effective building structure. This composite system offers opportunities to build high-rise buildings more efficiently, environmentally friendly, and safe, especially in earthquake-prone areas.

The Importance of Earthquake Resistant Buildings

Earthquakes are a significant threat to buildings, particularly in areas prone to seismic activity. The impact of an earthquake can be devastating, causing widespread damage and loss of life. In recent years, there has been a growing emphasis on building earthquake-resistant structures that can withstand the forces of an earthquake. This is where the steel-beton composite building comes in, offering a robust and durable solution to the challenges posed by earthquakes.

The Steel-Beton Composite Building Design

In this final project, an earthquake-resistant composite building is planned to refer to the 2010 earthquake map. The building consists of 10 floors with dimensions of 24 x 24 m2 and is planned to be in the city of Medan with soft soil conditions. The structural analysis is carried out using the ETABS v 9.5.0 program, while the design of the structural element is done manually with the LRFD (Load and Resistance Factor Design) method based on SNI 03-1729-2002. This structural design utilizes a special moment of the frame system (SRPMMK) and carries the concept of Strong Column Weak Beam (SCWB).

The Concept of Strong Column Weak Beam (SCWB)

The concept of Strong Column Weak Beam (SCWB) in this design ensures that the column has greater strength compared to beams. This allows the column to withstand a larger earthquake load, while the beam will experience deformation and absorb earthquake energy, thereby protecting the building structure from more serious damage. This design approach is particularly effective in earthquake-prone areas, where the ability to absorb and distribute seismic forces is crucial.

The Design Results

The design results show that the planned buildings have met the earthquake-resistant criteria according to ASCE 7-05 and SNI 03-1729-2002 standards. This indicates that this earthquake-resistant composite building is able to hold the earthquake shock safely. The use of composite technology in the construction of earthquake-resistant buildings is a significant step towards creating safer and more resilient structures.

Advantages of Earthquake Resistant Composite Buildings

The use of composite technology in the construction of earthquake-resistant buildings offers several advantages, including:

Stronger and Durable: The combined steel and concrete produce a sturdy structure and resistant to heavy loads, including earthquake loads.
Faster Built: Construction process using a composite system faster than conventional methods.
Environmentally Friendly: The use of steel reduces construction waste and minimizes the impact on the environment.
Efficient: The composite system allows the use of more optimal material, so it is more cost-effective.

Conclusion

The use of composite technology in the construction of earthquake-resistant buildings is the right solution to face future challenges. Strong, safe, and environmentally friendly buildings will be a high-value investment for the community and the environment. As the world continues to urbanize and face the threat of earthquakes, the need for earthquake-resistant buildings has never been more pressing. The steel-beton composite building offers a robust and durable solution to this challenge, providing a safer and more resilient structure for generations to come.
