Technology and system for ultrasonic inspection and monitoring of building structures
Record Control Number : 31440
Quality Validation Date : 2004-01-09
Update Date : 2004-01-29
Abstract : An Israeli SME has developed a new ultrasonic system for inspection
of building structures. The system detects non-invasively weak
points in the construction, estimates foundation degradation
velocity, predicts the structure behaviour under severe conditions
and reduces expenditures for building maintenance and renovations.
They are searching for financial resources and joint venture for
further development, manufacturing and marketing the system.
Current technologies on the market are incapable of predicting the
severity status of degradation in a building structure: some of
them are applicable only in laboratory conditions, in principle;
others provide only integral characteristics (average values of
parameters) or are very expensive. The new technology is based on
analysis of the propagation of elastic waves in heterogeneous
materials. The system includes proprietary probes or sensors,
automatic data acquisition software, a signal processing expert
system and a database for storage of inspection information.
The technology supplies vertical and horizontal section images of
the stress concentration within the building structure. The weak
points (high stress concentration) of construction and the
building structure flaws (cracks etc.) are revealed by 3D mapping
of various factors related to the stress and flaws in the structure
of heterogeneous materials. The weak points might be dangerous to
the integrity of the structure concerning future load conditions.
Information about corrosion in reinforced concrete structures or
stress characteristics of water-submerged foundations is also
The system supplies data for predicting a construction's
reliability under severe conditions; it is capable to detect
characteristics of water-submerged construction including
foundation swelling and degrees of softening of the waterlogged
concrete, caused by interaction with underground waters. The system
evaluates the ability of concrete and other building structures to
remain stable under present and future loads. It evaluates
quantitatively the degradation velocity of building foundation.
All this information enables early reinforcement of constructions
with minimal expenditures. The end-users may be buildings
maintenance companies, municipalities, building contractors, civil
engineering consultants, producers of prefabricated concrete
structures and parts, etc.
1. Detection of the location of weak points in a building
construction by non-invasive technology.
2. Evaluation of the foundations degradation velocity caused by its
interaction with underground water.
3. Prediction of the structure behaviour under severe conditions.
4. Cost-effectiveness: substantial decrease in expenditures for
building structure maintenance and renovation.
Innovative Aspects : Novel system and novel technology allowing:
a) Mapping the values of stress concentration factors in building
