Analysis of Reinforced Concrete Construction Calculations Based on the Ultimate Design Method and Elastic Method

Safe and economic construction of buildings requires special attention in planning and implementing. In this context, building regulations not only function as a practical guide, but also as a basis for ensuring that the structure built meets safety and efficiency standards. This writing will discuss reinforced concrete construction planning, especially in the beams and columns of the six-storey office building, by comparing the two main design methods: Ultimate design methods and elastic methods.

Understanding the Construction Calculation Method

Reinforced concrete construction planning involves the use of various design methods to ensure the safety and efficiency of the structure. Two of the most widely used design methods are the Ultimate design method and the Elastic design method.

Ultimate Design Method

The Ultimate design method considers reinforced concrete as a material that is not uniform (non-homogeneous) and is not entirely elastic. In this design, the safety factor and maximum capacity of the structure become the main focus, so the calculation must consider the possibility of the maximum load that may occur in the structure. This approach is based on the assumption that the structure will be subjected to various loads, including dead loads, live loads, and environmental loads, and that the structure must be able to withstand these loads without failing.

Elastic Design Method

Conversely, the Elastic design method treats the nature and behavior of reinforced concrete like steel. Here, the calculation focuses more on the elastic deformation of the structure, so that it emphasizes more on stiffness and deflection compared to the maximum capacity. This approach is based on the assumption that the structure will be subjected to various loads, but that the loads will be within the elastic limit of the material, and that the structure will be able to deform elastically without failing.

Comparison of Planning Results

From the results of the analysis conducted, found some significant differences between the two methods that affect the efficiency and safety of the structure:

Beam Reinforcement Efficiency

Based on the analysis using the SNI SK 03-2847-2002, the calculation of the beam reinforcement turned out to be more efficient at 42.44% when compared to PBI 1971. This shows that new regulations provide significant material savings without sacrificing security. The use of the Ultimate design method in beam reinforcement calculations resulted in a more efficient use of materials, while still ensuring the safety of the structure.

Column Reinforcement Efficiency

On the other hand, the calculation of column reinforcement in PBI 1971 shows a better efficiency of 38.85% compared to the SNI SK 03-2847-2002. This is caused by the dactail nature of the calculation of column reinforcement and shear reinforcement in new regulations that tend to be more complex. The use of the Elastic design method in column reinforcement calculations resulted in a more efficient use of materials, while still ensuring the safety of the structure.

Changes in Planning Standards

SK SNI 03-2847-2002 introduces changes and additional structural planning standards compared to old regulations, especially in terms of building efficiency and safety. This aims to compensate for the development of science and technology in the field of construction. The new regulations provide a more comprehensive approach to reinforced concrete construction planning, taking into account the latest advances in materials and technology.

Conclusion and Recommendations

The conclusion of this analysis shows that although the two methods have advantages and disadvantages of each, SK SNI 03-2847-2002 provides a more economical approach for beam planning, while PBI 1971 is still superior in column calculations. Therefore, it is important to take advantage of the latest rules in order to get optimal results in planning reinforced concrete structures.

It is recommended that the government can disseminate information about new regulations to development implementers, including students and professionals in the field of construction. This is important to increase understanding of the importance of applying new regulations and to meet the needs of the community in dealing with rapid technological advances. Through these efforts, it is expected that all stakeholders can produce buildings that not only meet security standards, but also efficient and economical.

Future Directions

The analysis of reinforced concrete construction calculations based on the Ultimate design method and Elastic method provides valuable insights into the planning and design of reinforced concrete structures. The results of this analysis can be used to inform the development of new regulations and standards for reinforced concrete construction, and to improve the efficiency and safety of reinforced concrete structures.

Limitations and Future Research Directions

This analysis has several limitations, including the use of a specific set of regulations and the assumption of a six-storey office building. Future research directions could include the analysis of reinforced concrete construction calculations using other design methods, such as the Limit State design method, and the development of new regulations and standards for reinforced concrete construction.
