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.

ROBO®CONTROL
Monitoring System
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.

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.
Key features
Lockable box

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.

systems. All components will be shipped to the bridge site after proper packing. The INCOTERMS in
their current version apply. The shipment will be received by the local contractor responsible for the
construction of the bridge and required import activities and duties will be obeyed. The transport
insurance covers transport only.
(4) Installation of the SHMS:
mageba estimates that the installation will require about 2 weeks, distributed in 6 visits. The
installation team consists of mageba specialists as well as local support staff (e.g. technicians,
electricians, drivers, etc.). The installation progress will be documented. In this way, possible delays
will be identified and adequate measures defined.
(5) Calibration and testing of the SHMS:
Calibration of all sensors and a function test of the complete installed system are included. A bridge’s
owner representative is invited to join the testing procedure. In this context, calibration means the
checking of the horizontal fixation of tilt-sensors, subtraction of static offset-values of accelerometers
and the like.

Offer nr. VOA000200
Permanent Monitoring of the
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
