Antiseismic Exoskeleton with Separating Cut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antiseismic systems for structures in seismic areas often result in oversized and bulky constructions due to high rigidity requirements, and they can exacerbate the issue of rising dampness, with existing solutions being invasive or ineffective.
Innovation Solution
A method involving a separating cut in the base portion of the structure, an exoskeleton, and panels with a cement cast, which reduces horizontal rigidity while maintaining vertical load-bearing capacity, and incorporates a gap to interrupt capillary dampness, allowing for thinner seismic action absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new outer casing made of concrete and insulating material is realised, then antiseismic protection is obtained, but the structure becomes oversized and bulky
Solution Approach 1:
The base portion of the structure is segmented from the rest of the building through a separating cut, allowing independent movement of the base during seismic events. This segmentation enables the upper structure to be protected with thinner antiseismic casing since the base absorbs and isolates seismic forces, reducing the overall volume of protective material needed.
2Reliability
If a new outer casing made of concrete and insulating material is realised, then antiseismic protection is obtained, but the phenomenon of rising dampness is exacerbated
Solution Approach 1:
A separating cut filled with flexible foam material acts as an intermediary layer between the base portion and the upper structure. This intermediary layer interrupts capillary action that causes rising dampness while allowing the antiseismic casing to be realised above the cut, thus preventing dampness progression without compromising seismic protection.
3Volume of moving object
If the rigidity of horizontal actions of existing masonry wall is reduced, then the antiseismic structure can absorb seismic action with lower thicknesses, but the load-bearing capacity towards vertical loads must be maintained
Solution Approach 1:
The structure is divided into a base portion and upper structure through a separating cut. The base portion retains full rigidity to support vertical loads, while the upper structure can be designed with reduced thickness since seismic forces are absorbed by the base and isolated through the flexible foam layer, resolving the contradiction between thickness reduction and strength maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables structures to absorb horizontal seismic actions with significantly lower thicknesses than traditional methods, reducing the risk of rising dampness and maintaining load-bearing capacity, while allowing for more economical and less invasive design.
Implementation Method 1
the synergistic action of the separating cut and of the antiseismic structure (exoskeleton, panels and cast of cement) enable capillary rising of dampness to be interrupted

AI summary
Method for realising an antiseismic system (1) for a structure (S) comprising the steps of realising an separating cut (2) in a base portion of said structure (S), realising an antiseismic structure (3) comprising the steps of fixing an exoskeleton (4) to the structure (S), fixing a plurality of panels (5) to the exoskeleton (4) maintaining a gap and introducing a cast of cement into the gap. The step of fixing the plurality of panels (5) and the step of introducing the cast of cement are realised gradually, from the bottom upwards, until the complete coating of the structure (S).
