Abstract The emerging modular building construction technique is gaining attention by researchers and investors because of its benefits such as short construction time, better quality control, minimal environmental effect and more economical. Composite modules have many advantages, including size reduction and improved fire resistance, over the steel modules, which encourage the application of modular construction on tall buildings. Current state‐of‐art lacks the proper connection technique for composite modular tall buildings. This paper presents novel inter‐module connection for composite modular tall buildings. Purposed inter‐module connection is very simple in geometric design, adequately strong to bear loads for tall buildings, easy to connect and disconnect, and applicable with internal joints and composite modules. Bolts through bolt holes connect modules vertically whereas gusset plate connects horizontally. Firstly, prototype is developed, and workability is confirmed. Performance and failure mechanism of proposed connector under tensile load are evaluated considering the effect of different parameters such as thickness of base plate, size and material of bolt. Results can be used to develop the design guideline for proposed inter‐module connection.
