Concrete buildings with modular systems are still not widely used for high-rise buildings. One of the main reasons is the lack of knowledge regarding the structural design of concrete modular buildings. In Indonesia itself, there are not even many concrete modular buildings because the majority of the area is surrounded by earthquake zones. This study aims to develop a frame analysis method using a section designer for structural analysis of concrete modular buildings. The function of using frame elements is to simplify the calculations that should be modelled with shell elements in order to ensure that the connection between segments occurred only vertically. The analysis was carried out for an 8-storey apartment modular building composed of 4 module segments (M-24A, M-24B, M-36A and M-36B). Seismic analysis was carried out using the parameters of the city of Kutai with Sds = 0.27 and Sd1 = 0.3. All module segments are capable of enduring the maximum moment caused by seismic loading. The M-36B segment has a maximum moment capacity of 62,318.73 kNm and can withstand an ultimate moment of 2,227.55 kNm. The combined effect of the earthquake due to the response spectrum created maximum building story drift of 0.11% does not exceed the required limit of 2%. © Published under licence by IOP Publishing Ltd.
