Abstract
The response modification coefficient (R) and the fundamental period of the structure (T) are the two main keys in determining the seismic design load of a building according to the current Indonesian Seismic Code, SNI 1726:2019. The code prescriptively requires that the values of R and T must be established based on the type of structural system. By developing a chart showing the relationships of the various structural systems, the number of stories, the height of the structure, and the approximate fundamental periods of the structure, a structural engineer can easily see which structural system is the most efficient to be applied in the design of buildings in earthquake-prone areas. This paper will demonstrate that the use of a special moment frame system can be much more economical than the dual system, which is more commonly used in practice. For a 32-story reinforced concrete office building, the seismic design load of the special moment frame system can be approximately 30% less than that of the dual system.
