The research subject is the rotational stiffness of the modular building metal frame nodal connection. The stiffness of nodal connections has a significant impact on the results of calculating the load-bearing frame of a modular building. It is known that absolutely rigid connections exist only in theory. In practice, each nodal connection has a finite stiffness, as evidenced by numerous studies of the researchers. When designing the real objects, the studies on the stiffness of nodal connections of a certain design should be carried out. As a rule, when designing real objects, there is no time to carry out the research. The designer operates with well-known and reliably proven recommendations. It is important for him to have the ready-made solutions for implementation in design practice. Such solutions can be provided on the basis of preliminary studies of the joints’ behavior of the structural elements under load. The article presents a solution to such a problem. The study of the stiffness of the nodal connection with the connected elements parameters variation has been carried out. The purpose of the study is to find the boundaries of design solutions at which the connection can be considered rigid.

The data reported by Japan Meteorological Agency (JMA) show that the fatal casualties and severe injuries are due to heavy shaking during massive earthquakes. Current earthquake-resistant building standards do not include comfort-level performance. Hence, a new performance design philosophy is proposed in this research to evaluate the quantitative effect of earthquake-induced shaking in a building. The earthquake-induced response accelerations in a building are analysed, and the response accelerations related with the characteristic property of the building are used to evaluate the number of Seismic Intensity Level (SIL). To show the indispensability of the newly proposed comfort-level design philosophy, numerical simulations are conducted to evaluate the comfort level on different floors in a building. The results show that the evaluation of residents’ comfort levels should be considered in the current earthquake-resistant building design codes.

“…e key to ensuring structural integrity [5][6][7][8][9][10][11][12][13][14] becomes joints/connections, which attracts wide attention from engineers and researchers. Further, the performance of the assembled modular structures has also been mainly focused on the performance under seismic actions and some other transverse loads/actions [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”

Modular structures are premanufactured off-site and assembled on-site, leading to reduced on-site works and construction periods and improved quality compared to conventional prefabricated steel structures and reinforced concrete structures. Meanwhile, steel frame-light gauge slotted steel stud (LGSS) walls have been considered to be assembled into the modules due to their excellent thermal- and sound-insulation properties. These structural components will also contribute to the resistance of the modular system when subjected to lateral loads/actions, especially seismic actions. A finite element model was developed to investigate the seismic performance of high-rise modular steel structures with LGSS shear walls. Then, parametric studies were conducted to investigate the influences of the layouts of the LGSS shear walls and structure heights on the lateral stiffness, the deformation modes, and the stress states of the modular steel structures. Observed from the results of a ten-storey modular steel structure infilled with LGSS shear walls, the maximum storey drift reduced by 50.1–79.50% compared to the corresponding pure steel frame structure under the selected high-intensity seismic waves. The results indicate that the studied modular steel structure with LGSS shear walls possesses good seismic resistance and could be a practical and economical choice for future modular constructions.
