“…Based on the available data, three-dimensional (3D) finite element model of Merah Putih Bride has been developed. Modification has been made from the previous study [3] by adding concrete deck element to the finite element model. To calibrate the finite element model of the bridge, dynamic properties of the three-dimensional model is compared with the dynamic properties of the actual bridge based on dynamic load test.…”

“…The bridge can be considered safe as long as there is no major power change in the cable system [1] Cable tension forces may vary with time due to load and ambient temperature variations at bridge location. Since the stayed cable is made of steel, ambient temperature variation is one of the important parameters which can affect the tension forces on cable [3]. However, the thermal effect is not only influenced by temperature variations, but also influenced by the existing structural conditions [6].…”

Cable is the main element of cable-supported bridge, such as suspension bridge, cable stayed bridge and arch bridge. For the cable-stayed bridge, the cable receives the load from the bridge deck and transfer it to the pylon. As the ambient temperature change, the internal force in bridge element including stayed cable will change. This research investigate the ambient temperature effect to the tension force of stayed cable of cable-stayed bridge by comparing the result of finite element model analysis with the field measurement form electromagnetic sensor data. The finite element model of Merah Putih Cable-Stayed Bridge has been developed based on detailed engineering design data. The finite element model is validated using the natural frequency data from dynamic load test of the bridge. The ambient temperature and bridge elements temperature were measured for 24 hours. The finite element analysis were conducted based on field measurement data and the contribution of pylon and girder temperature to the cable tension forces variation was investigated. The output of finite element analysis then compared to the actual cable tension as measured by an electromagnetic sensor. It was found that the ambient temperature will affecting the magnitude of tension force at stay cable and the variation of cable tension has similar pattern of both from the finite element model and electromagnetic data. As the temperature of bridge element increases or decreases, the bridge will experience a deformation. Since the stay cable connected to the pylon at one side and to the girder at the other side, its will make the stay cable elongated or contracted which in turn will affecting the tension force at stay cable. When evaluating the bridge condition based on the tension force at stay cable, the effect of temperature variation need to be considered.

“…The data from the dynamic test using accelerometer sensors are then processed by Fast Fourier Transform (FFT) to get natural frequencies of the cable structure. Based on the natural frequency value, the tension force of the cable can be calculated theoretically [3] [4]. Currently, the available techniques to estimate the cable tension are the static methods which directly measuring the tension by a load cell and the vibration methods which indirectly estimating the tension force from measured natural frequencies value [5] [6].…”

Cable is the main element in a long span structure and is often used for special structures such as long span bridges, roofs and other structures that require a long span. The stiffness of the cable is determined by the amount of axial tensile force acting on the cable, and hence, the magnitude of the actual tensile force on the cable is an important factor to be determined and monitored. One simple method for determining the actual tensile force on a cable is to calculate the tensile force from the first natural frequency of the cable. However, it is important to ensure that the formulas used to calculate the tensile force are accurate. This research aims to determine the level of accuracy and the factors that influence the accuracy of the formula to determine the tension force of the cable from the natural frequency value of the cable. The methodology used in this research project was by applying free vibrations to the cable with given axial tensile load and measuring the acceleration that occurred with an accelerometer sensor. By using Fast Fourier Transform (FFT), the natural frequency value of the cable can be calculated and the actual tensile strength in the cable can be determined. From the experiment conducted, it was found that the length of the cable affects the accuracy of the measurement of the natural frequency and the magnitude of tensile force of the cable. The strain that occurs on the cable plays a very important role to the accuracy of the formulas used.
