2.2 Analysed structure ‘New 4-Lane Cable Stayed ROB at Barddhaman”

The main bridge is a cable-stayed bridge of 208m with a main span of 124m. The bridge structures carries 4 road lanes divided in two carriageways. The pylon consists of 3 steel towers connected with a beam.

The mentioned structure is a good example of advanced civil engineering. The structural configuration is challenging, thus any miscalculation or mistakes done during construction can cause irreversible damages. To have a strong control on these critical issues, it is very convenient and helpful the use of a Structural Health Monitoring System. This kind of structure has to be instrumented with a sophisticated monitoring system. The proposed system is able not only to control the force distribution during construction of the bridge, but can also monitor all structural parameters during the service life. Important measurements are: cable forces. Additional parameters as accelerations, the opening of the expansion joints due to thermal expansions and unexpected deformations, temperature, humidity and wind sensors can be installed on the deck and pylon to detect the real structural behavior.

2.2.1 Proposed sensor layout

The Bridge Structural Health Monitoring System (BSHMS) is divided into two parts:

The on-structure instrumentation system

The data acquisition system for operation and control

The structural monitoring system issues alarms notification based on measurements by the on-structure instrumentation when pre-defined threshold values of structural loads are passed.

The alarm criteria will be configured based on the structural design of the bridge according to the sensors indicated in the following figures and the sensors listed below.

Sensors are included in the system as per the attached diagram below.

ROBO®CONTROL

Monitoring System





As per discussion at site the sensors would be installed at the pylon top end rather than the deck end as previously proposed by us.

Exact positioning of the sensors will be done according to situations at site.

The sensor which would be an annular sleeve would be installed inside the outer HDPE tube around the cable. It would be connected to the ROBO® Control Box via insulated wires. The ROBO® Control Box would be placed inside the hollow pylon.

As mentioned by the consultant a 5 mm hole would be made available in the cable anchor plate for the wiring to be led out from the sensor to the ROBO® Control box.

For visualisation, the below sketch could be used as a reference (not to scale).

2.2.2 Monitored variables of the structural response.

Load cell will be provided 2nos in each pylon. From a Pylon, 9nos of Staycable will be fixed at Backspan side and 9nos of Staycable will be fixed at Main span side. Out of 9nos, 1 stay cable will be with load cell arrangement at backspan side and any 1 stay cable will be with load cell arrangement at main span side. Similar arrangement shall be in all 3nos of pylons. So total load cell requirement is (3x2)=6nos for stay cable monitoring purposes and load cell will be fixed during execution of stay cable.

The positioning of all instruments follows the enquiry.

OPTIONAL Sensors:

Environmental factors (EC):

Wind sensor measuring wind speed and wind direction

Air humidity

Barometric pressure

Air Temperature to correlate all structural phenomena with environmental parameters (mageba offers optionally elaborated algorithms to eliminate the environmental effects and detect damage)

Structural Temperature in 6 positions

ultrasonic wind 3d

Vibration and Seismic events (SE):

Accelerometers to monitor seismic loads during an earthquake as well as traffic and wind load induced vibrations on the structure (3D or 2D – Seismic Accelerometers). Vibration measurements are taken on both decks but also onto the pylon to observe/compare the accelerations due to service loads and earthquakes on principal structural elements:

Accelerometers to monitor cable vibrations and consequently forces o accelerometer, on chosen suspension cables

Bridge structural response (BSR):

Deformation measurements by displacement sensors at bridge’s deck to monitor accumulated/current deformations on the structure.

o High precision measurement of the deck swing on longitudinal direction. o Alarm notification in case of defined threshold overpass.

2.2.3 Frequency of measurements

General environmental factors such as wind, air temperature, humidity and luminosity are sampled with a measurement frequency of 1 Hz. For sampling of all other sensors sampling frequency of 1-100 Hz will be provided. This rate allows evaluation of dynamic events. All data will be stored at the master station and is continuously screened. The processed data will be sent to the ROBO®CONTROL Web Interface.

The proposed sensors for dynamic measurements can be remotely controlled in order to enable changes of the measurement frequency. Setting of automatic frequency changes upon exceeding of defined threshold values is possible as well.

2.2.4 Sensor durability and protection rating

Where possible, the sensors will be installed in hardware cabinets in order to ensure a protection rating of IP65. The cabinets are of high quality stainless steel and robust construction, capable of resisting accidental impact and damage. The cabinets are lockable and capable of resisting attempted theft.

ROBO®CONTROL

Monitoring System





2.3 Detailed Sensor Description

A detailed description of the proposed sensors can be found in APPENDIX A.

All parts required for fixation of sensors is included:

Metallic sensor housings

Metallic straps for fixation

Cables

Lightning protection

Masts (GPS, Wind Sensors, Weather Station)

2.4 Power Supply of Sensors

The sensors require an uninterrupted 220V (110V) power supply. The power supply network of the bridge will be used. All on-structure sensors are plugged into cabinet-sockets within the appropriately designed and installed cabinets. The cabinet sockets are fed from a power cable connected to the dedicated power supply.

2.5 Analogue Cabling

The sensor will be connected to the local A/D converters by double shielded cables.

2.6 Digital Cabling

The local will be connected to the nearest connection panel of the fibre optic network of the bridge.

There is an electrical network on the bridge (not part of our offer).

Our sensors will always be connected to the nearest panel using analogue cable and local stand-alone A/D converters.

Our master station is in the control room and will be connected to internet there.

All masts and fixing parts are included in the offer.

High quality sensors (accelerometers) are used especially for the deck and seismic vibrations, because the bridge will have very low natural frequencies.

ROBO®CONTROL

Monitoring System





3. ROBO®CONTROL Data Acquisition and Transfer System

The ROBO®CONTROL data acquisition system is divided into a master-station and several substations (local A/D converters). This centralized setup allows a reduction of cabling and increases signal quality because of shorter analogue signal cables.

3.1 Master Station

The data acquisition unit is based upon industrial graded cPCI-Systems with high CPUs, running data acquisition and data calculating software. The A/D-conversion is done by multi-channel, 24-bit converter modules. The converters are placed to the sensors as close as possible. The master station is equipped with independent time-sources (GPS) to guarantee the highest possible self-sufficiency in the event of losing connection to the network. In such cases, full capability of preservation of evidence (traffic accidents, earthquakes) is given. The data acquisition unit is protected by an air-conditioned cabin to enhance reliability and durability. All master stations are connected together and can communicate with each other independently. The data is communicated in XML language. The master station is installed near the control room to allow easy access. The master station is protected by an isolated, air-conditioned/heated cabinet against the variable weather conditions on-site (-40°F to 176°F).

Figure 1: ROBO®CONTROL Master Station

3.1.1 Uninterruptible Power Supply – UPS

The master stations on the bridge can optionally be equipped with a UPS (uninterruptible power supply) in order to guarantee a power supply in the event of power interruption and to protect the equipment against fluctuation and voltage peaks of the public supply grid. The battery capacity will be adapted to the given power requirements in order to guarantee supply for up to 12 hours of interruption. The UPS will be charged from the power supply.

3.1.2 Software at master station

The software in the data-acquisition unit also controls the sensor functions and provides all measurement data with source code (name and position of sensor) and time stamp to allow accurate time synchronization. The raw data taken by all sensors of the monitoring system is stored on-site on 2 independent hard-discs to prevent data loss in case of disc failure. The measured values are organized in separated, compressed files; the administration and organization is done by a database system. The pre-processing of the monitoring data takes place at the master station. System identification algorithms are provided. Duhamel algorithm included.

3.1.3 AD-Converters (stand-alone units)

The National Instruments NI 9205 is a C Series analog input module for use with NI CompactDAQ and CompactRIO chassis. It features 32 single-ended or 16 differential analog inputs, 16-bit resolution, and a maximum sampling rate of 250 kS/s. Each channel has programmable input ranges of ±200 mV, ±1 V, ±5 V, and ±10 V. To protect against signal transients, the NI 9205 includes up to 60 V of overvoltage protection between input channels and common (COM). In addition, the NI 9205 includes a channel-to-earth ground double-isolation barrier for safety, noise immunity, and high common-mode voltage range. It is rated for 1,000 Vrms transient overvoltage protection.

1. Stay cable forces (installable only if cables are not erected)

Type of sensor: DynaMag

Total Number: 12

Figure 14: Electromagnetic Sensor for Cable Forces

Magneto elastic dynamometer DynaMag is intended for non-contact mechanical tension measurement in pre-stressed steel parts of suspended bridges and ground anchors. Pre-stressed steel parts are used as a sensor component of DynaMag system. Dynamometer DynaMag is designed for monitoring of supporting members in structures during their construction as well as for long-term monitoring during their entire lifetime.

This sensor has to be installed during stay cable installation because the strand has to be

pushed through the sensor. The position of the sensor is close to the upper stay cable

anchor.

Dynamag main features are as follows:

simple and clear principle

It is a direct measuring method utilizing the changes of physical properties of ferromagnetic materials after their mechanic load.

Pre-stressed parts of constructions are a component of magnetoelastic circuit of the sensor.

non-contact and non-destructive method

Direct physical contact between the sensor and the measured element is not required.

Allows measurement of mechanical stress through anti-corrosive protection of prestressed elements without damaging them.

The link between the measured element and the sensor is provided purely by means of magnetic field.

high accuracy and long term reliability

Sensors include neither moving parts nor parts that are liable to material ageing and performance reduction

Key features:

Non-destructive method

High accuracy and long-term reliability.

Direct measuring method, pre-stressed parts of

construction are direct component of the sensor

High resistance to dust, shocks, vibrations, water,

salt water, chemicals

Simple installation

Kota Bypass Cable stayed bridge, India

high durability of sensors

Sensors are resistant to dust, shocks, vibrations, water, salt water, water under pressure, chemicals and radioactive radiance.

unlimited lifetime of sensors

The life span of sensors exceeds the life span of standard constructions.

simple installation

The dynamometer DynaMag is designed for monitoring of supporting members in structures during their construction as well as for long-term monitoring during their entire lifetime. The sensor will be attached to one single strand whilst its installation. It is connected via e special readout unit with the monitoring system. For clear identification of sensors, all DynaMag sensors are equipped with electronic identifier and accurate thermometer, which measures the temperature of a construction in the sensor’s area.

mageba assume that the installation works for these sensors will take place in close coordination and cooperation with the stay cable supplier.

2. Signal cables (for analogue signals)

Figure 15: Double shielded signal cables

The signal cables connect all sensors with the digital conversion unit. To guarantee best signal quality the signal cables are double-shielded, have a cable attenuation of 9 dB/km@100 kHz and are therefore the best choice for completing an ambient vibration-based monitoring system. As the A/D-conversion takes place as close as possible to each sensor, the potential of interference is eliminated. In this way effective real-time data acquisition is possible.

Key features:

Cable attenuation 9 dB/km@100kHz

Double-shielded cables
