The development of design and innovation in the world of construction, especially in structures The building continues to grow along with developments in construction technology. One of the latest innovations in building construction design is the structural system modular, that is, a structural system consisting of separate modules prefabricated at the factory and put back together at the construction site. on structure modular there are limitations to the size of the module and the weight of the module from the transportation side, handling and erection. One solution to this problem is to using a composite modular structure with steel and concrete. Problems The main thing from the structural and constructional side of the modular structure is the connection, including intermodule connections, intramodule connections, module connections to foundations and module connections to the lateral force resisting structural system. Intermodule connection which is a connection that connects between 1 module with other modules into a unified modular system, will be studied in this research. Intermodule joints join the beams between modules and columns between modules so that they bear shear forces and moments acting on the beam and column. The strength and stiffness of the intermodule connection must be properly designed and not allowed to undergo plasticization beforehand before the beams and columns undergo plastification. In this study, module Typical composites will be designed using response spectrum analysis based on SNI standard 1726: 2019. Modeling is done using ETABS software assistance and manual calculations and responses are also carried out modular structure to variations in intermodule connection stiffness and variations earthquake loads will be studied. The stiffness of the intermodule joints studied are rigid and semi-rigid joints which varies with the stiffness of the column, x-beam and y-beam connections. The response of the composite modular structure to variations in the stiffness of the column joints, x-beams and y-beams with 4 case studies are examined. The simulation results show that the dominant influence of the stiffness of the connection is the intermodule connection column. Beam intermodule connections (x and y directions) give a not significant. Another study was conducted to determine the limit of the number of levels composite modular structure without bracing and shear walls viewed from the sides its strength and rigidity. Based on the simulation carried out that the limit increase in the number of storeys in a typical composite modular structure in this study is on the side of stiffness with the limit parameter, namely the inter- level.
