The security of the infrastructures is an important part and the responsibility of the nation. Therefore, the study is focused on investigating the seismic response of small-scale buildings through the shake table test. The small scale reinforced concrete building of two storey was modelled through the experiment as well as numerical simulations considering 40 MPa concrete strength. The size of the slab was 600 × 600 mm and thickness were 40 mm. The cross section of the column was 50 × 50 mm whereas the height was 300 mm. The galvanized wire was used as main reinforcement and stirrups bar having tensile strength 875 MPa and yield strength 636 MPa. The small-scale building frame was tested under the small-scale shake table which is working with adjustable speed by varying the voltage. The seismic waves were varied by considering different voltages such as 20, 40, 60 and 80V using the shake table. In order to minimize the percentage of error, more than 20 sets of observations were made at each of the voltage levels. The frequency of seismic waves such as 0.175, 0.348, 0.511 and 0.692/s was produced corresponding 20, 40, 60 and 80V, respectively. The displacement of slabs on the ground floor, first, second and third floor was recorded using the LVDT for the duration of 50 sec. The maximum top storey displacement was 50.45, 51.70, 55.31 and 61.04 against the frequency of 20, 40, 60 and 80V respectively. It was observed that the storey drift was ground, first and second floor was 0.42, 0.47 and 0.85, respectively at 60V. The numerical analysis was performed using ABAQUS finite element software incorporating concrete damage plasticity model and elasto-plastic model for concrete and reinforcement bar, respectively. The predicted storey drifts were found to be in good agreement with the experimental results corresponding to 60V. Further, the maximum peak positive acceleration predicted from the simulation was 4.72, 3.03 and 1.93g, respectively at the third (top), second (middle) and first slab (bottom), respectively.

“…Structural health monitoring (SHM) aims to provide a robust and effective approach to obtaining valuable information on structural conditions and supporting methodologies for the identification and, under specific conditions, localization of potential damages. Comprehensive reviews on SHM are available in [ 3 , 4 , 5 , 6 ], while their specific use in bridge monitoring is addressed in [ 7 ]. SHM can be implemented at either a global or local level [ 1 ].…”

Health assessment and preventive maintenance of structures are mandatory to predict injuries and to schedule required interventions, especially in seismic areas. Structural health monitoring aims to provide a robust and effective approach to obtaining valuable information on structural conditions of buildings and civil infrastructures, in conjunction with methodologies for the identification and, sometimes, localization of potential risks. In this paper a low-cost solution for structural health monitoring is proposed, exploiting a customized embedded system for the acquisition and storing of measurement signals. Experimental surveys for the assessment of the sensing node have also been performed. The obtained results confirmed the expected performances, especially in terms of resolution in acceleration and tilt measurement, which are 0.55 mg and 0.020°, respectively. Moreover, we used a dedicated algorithm for the classification of recorded signals in the following three classes: noise floor (being mainly related to intrinsic noise of the sensing system), exogenous sources (not correlated to the dynamic behavior of the structure), and structural responses (the response of the structure to external stimuli, such as seismic events, artificially forced and/or environmental solicitations). The latter is of main interest for the investigation of structures’ health, while other signals need to be recognized and filtered out. The algorithm, which has been tested against real data, demonstrates relevant features in performing the above-mentioned classification task.

“…In contrast to visual inspection approaches, vibration monitoring-based methods operate on a clearer physical mechanism [26,27], primarily performing the structural damage assessment based on the damage indexes extracted from the structural vibration response [28,29]. In general, the vibration responses of structures are obtained by a monitoring system through sensors (such as accelerometers, displacement sensors, and inclinometers) distributed along the structure [30,31].…”

Rapid and accurate structural damage assessment after an earthquake is important for efficient emergency management. The widespread application of surveillance cameras provides a new possibility for improving the efficiency of assessment. However, it is still challenging to directly assess the structural seismic damage based on videos captured by indoor surveillance cameras during earthquakes. In this study, we elaborate on the concept of estimating the structural natural frequency based on the relative pixel displacement of inter-stories. Furthermore, we propose a strategy for post-earthquake structural damage assessment that integrates the computer vision and time-frequency analysis. This approach aims to navigate the difficulties inherent in earthquake damage assessment and improve emergency responses. The relative pixel displacement between the camera and the fixed features on the floor is extracted from videos by using the Harris corner detection and Kanade–Lucas–Tomasi algorithms. The structural natural frequency is estimated using the synchroextracting transform-enhanced empirical wavelet transform. The natural frequency shift-related seismic damage index is defined and calculated for damage assessment. A shake table experiment of a small-scale steel model is conducted to verify the accuracy and feasibility of the approach, and the practicality of the proposed approach is further verified by utilizing the data from a full-scale reinforced concrete benchmark model experiment. The results demonstrate that the approach can accurately and efficiently evaluate the structural damage after an earthquake based on the video captured by surveillance cameras during the earthquake. The error of the acquired damage index is less than 0.1. We will apply more advanced algorithms in the future to alleviate this problem.
