“…For the detailed study on the structural performance of the modular frame system with developed joint, various standard analysis and design approaches were adopted. Material and sectional properties used in the FE analysis were chosen from experimental data [31,32]. The tenons in the joint were the main component for supporting columns and horizontally connecting modular units.…”

Prefabricated modular steel (PFMS) construction is an industrial technique of construction that enhances productivity, site safety, and construction quality. The assembling of prefabricated buildings needs an accurate connecting system to ensure structural integrity and effective transfer of loads and moments. Therefore, in the current study, a new-type bolted joints having a long tenon-gusset plate for horizontally, and long beam bolts for vertically connecting modular units have been developed. Nonlinear static analysis was carried out by the finite element (FE) analysis software ABAQUS. The bending performance of the joints with varying parameters and modular units with different forces scenario, was studied. To analyse the seismic performance of modular steel building (MSB), a simplification of the detailed joint with the connector was performed. Then the seismic response of full-scale four-storey simplified MSB was studied by dynamic analysis. The results revealed that joints possessed stable load-carrying capacity with adequate ductility and seismic performance. The simultaneous application of axial, lateral tension, and compression forces affected ultimate capacity, initial stiffness, and ductility of single modules more than the double modules. Moreover, the simplified model accurately mimicked the bending behaviour of joints with a fluctuation of < 4% in capacities. Inter-storey drift ratios (IDR) of both the shorter and longer directions of MSB were found lower than the code limits of 2.5%. Hence, the static analysis on joints and modular units, and dynamic analysis on MSB authenticated the effectiveness of developed joints to resist and distribute the lateral loads. Finally, the accuracy of FE analysis was verified by analysing twelve bending tests on joints listed in the references.

“…If we look at the problem of building industrialization with an eye towards product manufacture, modular design, and the overall construction methodology, most components are prefabricated at the factory and assembled on-site. In such cases, building space is integrated, construction time is minimized, and on-site construction errors are reduced (as shown in Figure 1) [10,11]. Modular design also embodies the concept of sustainable development and "green" construction.…”

Modular prefabricated buildings effectively improve the efficiency and quality of building design and construction and represent an important trend in the development of building industrialization. However, there are still many deficiencies in the design and technology of existing systems, especially in terms of the integration of architectural performance defects that cannot respond to occupants' comfort, flexibility, and energy-saving requirements throughout the building's life cycle. is research takes modular prefabricated steel structural systems as its research object and sets the detailed design of an integrated modular envelope system as the core content. First, the researcher chose two types of thermal insulation materials, high insulation panels and aerogel blankets, in order to study the construction details of integrated building envelopes for modular prefabricated buildings. Focusing on the weakest heat point, the thermal bridge at the modular connection point, this work used construction design and research to build an experimental building and full-scale model; the goal was to explore and verify the feasibility of the climate-responsive construction technique called "reverse install." Second, as a response to climate change, building facades were dynamically adjusted by employing different modular building envelope units such as sunshades, preheaters, ventilation, air filtration, pest control, and other functional requirements in order to improve the building's climate adaptability. Finally, based on the above structural design and research, this study verified the actual measurements and simulation, as well as the sustainability performance of the structure during the operational phase, and provided feedback on the design. e results highlight the environmental performance of each construction detail and optimized possibilities for an integrated envelope design for modular prefabricated buildings during both the design and renovation phases.

“…In the prefabricated concrete frame structure, the connection mode of column, beam and floor, especially the connection mode of beam-column joint, is the fundamental to distinguish the assembled structure from the cast-in-place structure, and it is also the core stress part that affects the seismic performance of the whole structure [5][6] . However, the joint area of prefabricated concrete frame structure is its weak link, especially the connection of beam-column joint directly affects the stability and seismic performance of the whole structure.…”

As an efficient, eco-friendly and economical solution for connecting precast concrete components, grouted sleeve connectors aroused widespread interest in engineering site. However, as the key material of grouted sleeve connection, grouting material needs to provide enough good performance to meet the engineering requirements. In order to better design the mix proportion of grouting materials, this paper studies the influence of water binder ratio, carbon fibre content, expansion agent addition and other factors on the performance of grouting materials, and optimizes the mixture ratio of grouting materials by analyzing the workability, compressive strength and expansibility, and analyzes the bonding performance of grouting materials by using the half-grouting steel sleeve connector.
