Steel and concrete are the main buiding material of the civil engineering community, but with its easily errosion behaviour and CO2 discharge, it should be substituded with new materials.Fiber reiforcement polymer (FRP) is such a developped material, with its high strength to weight ratio, durability prolongation, hight stiffness to weight ratio and its fatigue resistance behaviour, it is now getting widely used in civil engineering. This article focused on how to design, built and operate a structure health monitoring system for the noval steel-free cable stayed bridge, and a knowledge discovery model, SG(Simplified-General)modle was provided for analyzing the collected data.

State monitoring is one of the important part of the structure healthy monitoring system, the dynamic characteristics of structures are evaluated rather frequently by measuring their vibrations. With the research and application going in deep, wireless sensor is a perfect way to expand the range of the structure health monitoring system. This dissertation started with a concept design of a wireless sensor that could be used in the structure health monitoring system. In this paper, the state monitoring of civil engineering structure by using wireless sensor technology has been gave out based on monitoring technology and network protocol analysis. Design and hand make the front-end measurement circuit board and software for secondary development based on the monitoring equipment of company. The monitoring network has been set up and experiments were carried out about the structure deformation in the standard steel beam of civil engineering structure laboratory.

Intelligent health monitoring system of the long-span railway cable-stayed bridge requires the comprehensive knowledge of instrumentation, analytical and information processing technologies with the knowledge and experiences in design, construction, operation and maintenance of railway cable-stayed bridge for long-term monitoring the performance throughout its lifecycle. It is necessary to perform sensor-based structural monitoring for identifying the bridge conditions in order to assure the structural safety and to evaluate the operational performance. The considerations for deploying a proper monitoring system are appropriate sensor instrumentation, robust signal acquisition, reliable signal processing, and intelligent signal and information processing. The experience on developing an autonomous monitoring system in the one certain railway cable-stayed bridge newly constructed is introduced in this paper. Sensor and hardware instrumentation, signal transmission, signal acquisition and analysis are schematically described mainly. Experience through this work will be worthwhile lessons for other similar efforts.

<p align="center"><strong>Abstrak</strong></p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Salah satu isu utama dalam setiap penerapan <em>Structure Health Monitoring System</em> (SHMS) jembatan bentang panjang khususnya jembatan Pulau Balang II adalah bagaimana membuat SHMS tersebut dapat diandalkan secara efektif. Penggunaan sensor yang terlalu banyak tidaklah efisien demi mendapatkan informasi yang selengkap-lengkapnya terkait kondisi jembatan. Tujuan utama riset ini adalah untuk menganalisia tipe sensor, posisi penempatan sensor dan jumlah sensor yang akan dipasang pada SHMS jembatan Pulau Balang sesuai kebutuhan sensor yang efektif dan efisien. Pengamatan SHMS meliputi lendutan dek, pylon serta tegangan dek, pylon. Metode penelitian berupa pengamatan langsung di lapangan, analisa data dan diskusi dengan stakeholder jembatan. Dari hasil analisis terdapat 13 jenis sensor yang sebaiknya dipasang pada SHMS Jembatan Pulau Balang dengan total kebutuhan sensor berjumlah 87 buah. Posisi penempatan sensor sebagian besar ada di pylon, kabel dan dek yang disesuaikan dengan tipe jembatan yaitu cable stayed. Untuk sensor gempa disarankan perlu dipasang hal ini dikarenakan wilayah tersebut memiliki seismistis paling rendah yang didominasi oleh tiga zona sesar utama yaitu sesar mangkalihat, sesar tarakan dan sesar maratus oleh karena itu Kalimantan bukanlah daerah yang bebas gempa bumi.</p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Kata kunci: <em>structural health monitoring system</em><em> (SHMS),</em><em> sensor, p</em><em>ylon, dek, cable stayed</em></p><p class="11daftarpustaka"> </p><p align="center"><strong> </strong></p><p align="center"><strong>Abstract</strong></p><p class="11daftarpustaka"> </p><p>One of the main issues in each application of Structure Health Monitoring System (SHMS) in long span bridge particularly Pulau Balang II Bridge is how to make the SHMS effectively dependable. The excessive use of sensors is inefficient in order to obtain complete information regarding the condition of the bridge. The main purpose of this research is to analyze the type of sensor, the position of the sensor placement and the number of sensors that will be installed on the SHMS structure of the Balang Island bridge according to the need for effective and efficient sensors. SHMS observations include deck deflection, pylon and deck stress, pylon. The research method is in the form of direct observation in the field, data analysis and discussions with bridge stakeholders. From the results of the analysis, there are 13 types of sensors that should be installed on the Balang Island Bridge SHMS with a total sensor requirement of 87 units. Most of the sensor placement positions are in the pylons, cables and decks that are adapted to the type of bridge, namely cable stayed. For earthquake sensors, it is recommended to install this because the area has the lowest seismicity which is dominated by three main fault zones, namely the Mangkalihat Fault, Tarakan Fault and Maratus Fault. Therefore, Kalimantan is not an earthquake-free area</p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Keywords: <em>structural health monitoring system</em><em> (SHMS),</em><em> sensor, pylon, deck, cable stayed</em></p>

The Junshan Yangtze River Bridge, built in Wuhan, China in 2001, is a steel box girder cable-stayed bridge with a main span of 460m. Due to decades of service, the bridge suffered gradual degradation and some damage. Structural health monitoring has attracted worldwide attention due to its capacity of monitoring structural damage, assisting maintenance and management, and ensuring safe operation of bridges. To monitor the performance status of bridges and generate a timely safety alarm, an integrated health monitoring system has been designed and implemented on bridges. This paper provides a thorough account of the monitoring system used at the Junshan Yangtze River Bridge. It mainly focuses on the selection of monitoring variables and arrangement of sensor points, the data collection and transmission system, the data storage and management strategy, and the user interface system. All kinds of monitoring data collected under daily operation, such as vehicle load, deflection, displacement, and cable tension, are analysed. Monitoring data for an extreme condition, which involves two heavy trucks of 178 tons moving across the bridge, are also analysed. The results indicate that the monitoring system works well and that some local welded joints may experience fatigue damage.
