Beam Console Deforming Section for Structural Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for supporting beams in building frame structures fail to maintain the beam's attachment to a support structure when the opposing support structure is damaged, leading to potential structural instability and damage.
Innovation Solution
A method involving a first console extending from the support structure with a deforming section and a mechanical joint that secures the beam, allowing it to remain attached even if the opposing support is lost, utilizing a supporting slot and external fastening means like bolts or serrated plates, ensuring the beam's stability without damaging the support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a beam is supported between two support structures using conventional methods, then the beam is stable under normal conditions, but the beam cannot remain attached to one support structure if the opposing support structure is damaged
Solution Approach 1:
The connection system is divided into separate components: a console attached to the first support structure, a beam with a supporting slot, and external fastening means. This segmentation allows the beam to remain connected to the first support structure even if the second support structure fails, as the console and fastening means form an independent attachment system.
Solution Approach 2:
The console is pre-attached to the first support structure before the beam is installed. The supporting slot is pre-formed in the beam. This preliminary preparation ensures that when the second support structure is damaged, the beam can immediately rely on the pre-positioned console and external fastening means to maintain attachment to the first support structure.
2Reliability
If external fastening means are used to secure the beam to the console, then the beam remains attached during support structure damage, but the device complexity increases
Solution Approach 1:
The console acts as an intermediary element between the first support structure and the beam. It provides a dedicated attachment interface with the supporting slot and external fastening means, separating the beam connection function from the support structure itself. This intermediary approach maintains reliability while organizing complexity into a dedicated component rather than complicating the overall system.
3Stability of the object's composition
If the beam is secured against movement along the console by mechanical joint, then the beam stability is improved, but the deformability of the console is reduced
Solution Approach 1:
The console is designed with non-uniform properties: the region containing the supporting slot and external fastening means has enhanced rigidity to secure the beam, while other portions of the console maintain appropriate deformability to accommodate structural movements and stresses. This local differentiation allows simultaneous achievement of beam stability and console adaptability.

AI summary
Described is a method and an arrangement for supporting a first beam (1) between a first support structure (2) and a second support structure (20) in a building frame structure. The method includes securing the first beam (1) to a first console (9) against movement along the first console (9) by means of a mechanical joint (15) between the first console (9) and the first beam (1), and providing the first console (9) at a location between the beam supporting surface (11) of the first console (9) and the mechanical joint (15) with a deforming section (16) having increased deformability compared to the deformability of the first console (9) at the beam supporting surface (11) by providing reduced material dimensions in said deforming section (16) of the first console (9) compared to the material dimensions of the first console (9) at the beam supporting surface (11).
