Since then, the utilization of steel as a structural material has been on the rise. However, there have been numerous shortcomings in the seismic design of steel structures. Therefore, this article presents the results of a scientific review of the development of steel structures in Indonesia, both regarding the development of codes and their applications. In Indonesia, a significant number of steel buildings employ a haunch in their beam-column connections within a moment-resisting connection system. Haunched systems are not described in AISC 358 as permitted connections for earthquake-resistant buildings. Recently, Europe has published European Prequalified Steel Joints (EqualJoints). Four types of connections are discussed, and one of them is the haunched type connections. The haunched connection meets the seismic requirements to be suitable for use as an earthquake-resistant connection in Europe. This can be used as a reference if we are going to design a haunched connection in Indonesia. However, special attention should be paid to the details. The bolt configuration, the thickness of the end plates, and the shape of the haunch are not like those commonly used in Indonesia; there must be improvements to be adjusted in EqualJoints so that the performance of the connection against earthquakes becomes more guaranteed. Keywords—beam-column; connection; haunched; Indonesia; Europe; AISC 358; EqualJoints I. Introduction Indonesia's position in the Ring of Fire causes most of its territory to be at high earthquake risk [1]. Most of the largest earthquakes that have ever existed in the world have occurred in Indonesia, Figure 1 illustrates the high potential for seismicity in Indonesia, 25% of severe earthquakes occurred in Indonesia. The General Insurance Rating Organization of Japan (2014) even states that the regions with the highest earthquake intensity are Japan, Indonesia, and New Zealand [2]. The high earthquake potential makes the tendency of research on steel structures always lead to earthquake resistance. The development of research on steel and its application in Indonesia is not as advanced as in other developed countries [3]. While the recent codes are up to date, the research and application are still behind, especially in the area of seismic-resistant steel structures. There is a gap between steel structure research and its application in the field. Therefore, this article was created to provide a scientific review of Indonesia’s current development of steel structures. Figure 1.

There are many inconsistencies with the current code, such as the selection of materials, the size of cross-section availability, and the connection systems [4].
