Prefabricated frame structures are widely used due to their flexible building layouts, spacious interiors, ease of separation, and excellent ductility. These features make them a popular choice in prefabricated construction projects.
Design Principles for Multi-Story Frame Structures
Holistic Approach
In multi-story buildings, the floor system plays a crucial role in maintaining the overall structural integrity. It provides adequate in-plane stiffness and resistance, and must be securely connected to the vertical substructures. Special attention is required when the structure is open, the floor plan is narrow or irregular, or when large openings are present in the floor.
Ensuring the integrity of the foundation in multi-story and high-rise buildings, along with a reliable connection between the foundation and the superstructure, is essential for the overall stability of the building.
Key Considerations for Installing Multi-Story Frame Structures
Component Layout and Stacking
Prefabricated components should be positioned within the crane’s operational range as much as possible to minimize secondary handling. Heavy components are best placed close to the crane, while small and medium-sized components can be arranged around the perimeter of the heavy elements. If it’s impossible to keep all components within the crane’s reach, some smaller parts may be temporarily stacked near the building site and transported to the lifting area using appropriate handling equipment during installation.
