Areal Building Elements With Crosswise Reinforcement Layers
Solution Overview
Problem
Building elements, such as walls, face challenges in resisting high stresses and impacts from various directions without compromising ductility, as traditional reinforcement methods either reduce ductility or fail to provide adequate resistance against multi-directional forces.
Innovation Solution
The use of an areal building element composed of two partial elements with equidirectional and crosswise reinforcement layers, where the first reinforcement layer intersects only with the side faces of the first partial element and the second reinforcement layer intersects with the main surfaces of the second partial element, enhancing resistance against external impacts and multi-directional stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stronger or thicker grids or plates are used as reinforcement means, then the strength of building elements is improved, but the ductility is reduced
Solution Approach 1:
The patent transitions from traditional planar reinforcement (parallel to wall surface) to three-dimensional reinforcement structures that extend in multiple spatial directions. Reinforcement elements are arranged both parallel and perpendicular to the wall surface, creating a volumetric reinforcement system that provides strength while maintaining ductility through multi-directional stress distribution.
Solution Approach 2:
The patent combines different types of reinforcement elements (grids, meshes, plates, fibers) with different orientations and properties to create a composite reinforcement system. This composite approach allows the building element to achieve both high strength and good ductility by leveraging the complementary characteristics of different reinforcement materials and configurations.
2Strength
If traditional reinforcement methods are used, then the building elements can resist forces in one direction, but they fail to provide adequate resistance against multi-directional forces
Solution Approach 1:
The patent introduces reinforcement elements that extend in multiple spatial dimensions, including perpendicular to the wall surface. This multi-dimensional arrangement enables the building element to resist forces acting from different directions, improving adaptability to multi-axial loading conditions while maintaining structural strength.
Solution Approach 2:
The reinforcement system is designed to perform multiple functions simultaneously: it provides strength in both parallel and perpendicular directions, enhances ductility, and offers resistance against various types of loads (compressive, tensile, shear). This multi-functional design allows a single reinforcement system to address diverse structural requirements.
