The force balance of building nodes is a critical link in steel structure frames, which is related to the safety of the overall structure; The design and development of node supports are facing constantly changing challenges with the gradual improvement of engineering design level. It is our duty to continuously provide first-class design solutions and high-quality products for the project.
As an important force transmitting component of spatial structures, the mechanical properties of nodes and their consistency with the overall structural analysis model in terms of force transmission and deformation performance are important foundations for ensuring the safety and applicability of spatial structures.
With the continuous emergence of various new structural systems, the connection forms of structures are becoming increasingly diverse, requiring certain nodes to have spatial rotation and force transmission characteristics. The pin type hinge joint can rotate freely in one direction, but cannot rotate in other directions; To meet the spatial rotation and three-way force transmission requirements of certain nodes in complex spatial structures, a mechanical joint bearing has been introduced into structural engineeringSpherical Plain BearingAs a rotating core, it can truly achieve three-dimensional force and hinge connection performance in space, while also improving the seismic performance of the structure; And the derived performance of strong wind resistance, temperature difference resistance, displacement, and turning angle. The results indicate that a well-designed joint bearing node is fully applicable to building structures.
