Optimization of frames for effective assembling (FRAMEUP) : final report

The main achievements of the research project are the development of a construction process for a modular building based on a lifting-up technique. This includes execution of a building from the roof to ground floor and the assembly of frames and 3D room modules. This process is fully visualised for identification of possible conflicts during the execution and to promote the project goals towards industry and society for benefits of stakeholders. A portable lifting device consisting of a self-climbing device and climbing columns are developed and tested. Different types of beam-column joints are investigated in order to ensure quick assembling and to guarantee the stability of the non-braced structure even in certain earthquake regions. Verification of the resistances of joints at ambient and elevated temperatures, under monotonic and cyclic loadings are done by means of experiments and Finite Element studies. Furthermore, the robustness of a six-storey modular building is assessed and a risk assessment of potential perilous situations are carried out. A pilot building structural frame is executed at indoor conditions and monitored in order to investigate the feasibility of the construction process. Sustainability aspects are addressed and a comparative LCC analysis is performed to verify the advantages of the concept. The building physics performances of the 3D room modules are investigated by experiments. Finally, design models and guidelines for predicting analytically behaviour of column bases, beam-to-column joints and column splices based on the component method are proposed. These design recommendations are consistent and complementary to EN1993-1-8.
