STRUCTURAL DAMAGE DETECTION SYSTEM WITH MULTIPLE FRAGILITY CONDUCTIVE SENSORS

Abstract

The invention is a structural damage detection system that converts physical damage in the load-bearing structural elements (3) of buildings into a percentage rate in real time. The system includes multiple fragile conductive lines (2) placed longitudinally on the lower surface of the load-bearing structural element subjected to tensile force, and a lower covering plate (1) that protects them from external factors. Transverse cracks in the structure break the conductive lines (2), disrupting electrical continuity. This data, received via the data acquisition terminal (4), is converted into a damage rate by the microcontroller (5) and transmitted to the alarm interface (6).

Description

1 TARIFF STRUCTURAL DAMAGE DETECTION SYSTEM WITH MULTIPLE FRAGILITY CONDUCTIVE SENSORS TECHNICAL FIELD The invention concerns a system that monitors the structural integrity of buildings and the load-bearing elements. a system that instantly detects critical damage and presents this damage as a mathematical ratio. structural damage detection system. STATE OF THE ART With current technology (in known cases), it is possible to monitor the structural health of buildings and earthquakes. Damage assessment after the event typically requires expensive accelerometers and complex fiber optic cables. Optical sensors or p-shaped electrical systems requiring special calibration are used. These 10 The systems are difficult to install, the costs are high, and they are susceptible to external interference (vibration, noise, objects). It is sensitive to damage (transportation, etc.). In addition, known systems determine the physical extent of damage occurring in the structure. It falls short in providing real-time and regional data as a "percentage rate". The subject of the invention is a structural damage detection and early warning system, which overcomes the disadvantages of existing technologies. It was developed to eliminate it. 15 THE PURPOSE OF THE INVENTION AND THE TECHNICAL PROBLEMS IT SOLVED. Direct Tensile Force and Crack-Focused Detection: Flexural deformation of reinforced concrete structures. It is a static fact that structural cracks initially begin from the bottom (tensile) surface of the element. Considering this; the system directly connects to the bottom surface of stairs, beams or columns. It is positioned in such a way that instead of indirect vibrations, the physical vibrations in the building's skeleton are directly 20 It detects separation (cracking) instantly. Transverse Crack Detection Guarantee: For conductive lines, ladders or... Thanks to the fact that the beam is laid longitudinally (parallel to the slope or length) in the structure, potentially fatal transverse cracks could form and cut the sensor lines at a key angle. By detaching it, it was ensured that it was detected with 100% accuracy. 25 Preventing False Alarms and External Interference: Conductor lines, concrete main Thanks to its "sandwich" shape concealment between the body and the outer protective plaster / sheet layer, system protection against user-induced physical impacts (stepping, bumping into objects, surface abrasion) It is completely isolated; the risk of false alarms has been reduced to zero. Percentage Damage Mapping: Multiple and parallel conductor lines (e.g., 30 (number of lines) and the integration of these lines into a single data collection terminal Thanks to this, the extent of damage in that area of ​​the structure can be determined based on the data of "how many lines were broken". This can be converted into a mathematical percentage value (for example, 15% or 80% damage). Low Cost and Easy Implementation: No complex calibrations or expensive processes. Because it works solely on the principle of physical conductivity / breakdown without requiring optical readers, 35 It can be easily integrated into all existing or newly constructed buildings at extremely low cost. ed leb lrbr offers a structure.

Output Layer (Alarm and Damage Detection Interface) DETAILED DESCRIPTION OF THE INVENTION In the preferred configuration of the invention (Figure 1), Multiple Fragile Conductor Lines (2) the sub-surface that is directly subjected to tensile stresses of the load-bearing structural element (3) It is placed. In this placement, Multiple Fragile Conductor Lines (2) are placed in parallel with each other and 15 The load-bearing structural element (3) is positioned so that it extends along the longitudinal axis. Multiple Fragile Conductor Lines (2) from physical shocks, humidity or external environment To prevent wear and tear caused by user activity, a bottom coating plate is applied to these lines. (1) is applied. In this way, Multiple Fragile Conductor Lines (2), Carrier Structure Element (3) and Sub The cladding plate (1) is enclosed within a protected "sandwich" structure (Figure 2 20). (Figure 3). Working Principle b and Damage Assessment: Reinforced concrete structures, earthquake or overload damage. When it flexes instantly, the first structural cracks appear at the base where the tensile strength of the concrete is lowest. It starts on the surfaces. Multiple Fragile Conductor Lines (2) are placed longitudinally on these surfaces. Any transverse crack occurring in the structure and intersecting these lines at a key angle 25 It is designed to physically break during its formation. The system data flow process (Figure 4) consists of the following steps:  Physical Data Input: A certain number of Multiple Brittle segments resulting from cracking in the structure. The electrical continuity in the circuit is disrupted by the breaking of the conductive lines (2).  Data Collection: From all Multiple Fragile Conductor Lines (2) 30 (whether broken or intact) The incoming continuous data are collected at the Data Collection Terminal (4) and converted into digital signals. It is transformed.  Mathematical Processing: Microcontroller (5), Data Collection Terminal (4) Based on the data, the carrier structure is calculated by ratioing the total number of lines to the number of broken lines. Convert the element (3) into a percentage value. For example; 5 35 from 20 lines. If the grain breaks, the system will be diagnosed with "%25 structural damage" in the affected area. He puts it there.  Warning and Notification: This calculated damage rate is transferred to the Output Layer (6) and sent to the building. The information provided to the authorities regarding the evacuation and intervention decisions is definitive. The invention, due to its function as an escape route during an earthquake, consists of 40 load-bearing structural elements. (3) Although it is designed on the main body of the staircase, which is brs; the same working principle and the layered structure (1, 2, 3) is preserved, including all critical parts of the building such as beams, columns and shear walls. It can be applied to load-bearing points. This flexible structure of the system allows for digital installation throughout the entire building. It allows for the creation of a "damage map". 45
