Offset Core Structure for Asymmetrical Building Designs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional building techniques, relying on a foundational structure with a central core and attached steel framework, limit modern building design advancements and prevent the creation of asymmetrical or larger-than-footprint structures.
Innovation Solution
The use of an offset core, a truss assembly, and a floor tying assembly, where the offset core is positioned proximate the periphery and the truss assembly forms a moment stabilizing structure with diagonal braces, allowing for larger and asymmetrical designs by transferring loads effectively and canceling moments at the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional building techniques with central core and steel framework are used, then structural stability is maintained, but design flexibility and asymmetrical configurations are limited
Solution Approach 1:
The patent applies asymmetry by positioning the core offset from the geometric center of the building footprint. This offset core configuration enables asymmetrical floor plate arrangements and allows the building to extend beyond its footprint in certain directions, breaking the symmetry constraints of traditional central core designs while maintaining structural stability through the moment stabilizing structure.
Solution Approach 2:
The patent utilizes another dimension by allowing floor plates to extend beyond the building's footprint, creating cantilevered sections that project outward. This dimensional extension is made possible by the offset core configuration and moment stabilizing structure, which together provide the structural support needed for floors to overhang the building base.
2Adaptability or versatility
If offset core configuration is used to enable asymmetrical designs, then design freedom increases, but structural complexity and load distribution challenges increase
Solution Approach 1:
The patent applies the counterweight principle through the moment stabilizing structure, which uses diagonal bracing and strategically positioned structural elements to counterbalance the moments generated by the offset core and cantilevered floor plates. This moment stabilizing system acts as a counterweight mechanism that neutralizes the destabilizing effects of asymmetry.
Solution Approach 2:
The patent applies segmentation by dividing the structural system into distinct components: the offset core, moment stabilizing structure, and floor plate assemblies. This segmentation allows each component to be optimized independently and simplifies the overall structural analysis and construction process while enabling asymmetrical configurations.
3Area of stationary object
If floor plates extend beyond building footprint, then building width and depth increase, but load transfer requirements and foundation demands increase
Solution Approach 1:
The patent applies the intermediary principle by introducing the moment stabilizing structure as a mediator between the cantilevered floor plates and the foundation. This intermediate structural system transfers and distributes the loads from the extended floor plates through the offset core to the foundation, reducing the direct load demands on the foundation while enabling larger building dimensions.
