“…Hesami et al [17] employed a 2D FEA for modeling of the train movement and its effect on the nearby building and showed that the vibrations increased by increasing the speed of the train and decreased by decreasing the speed of the train while the distance between the railway and the building affects the values of vibrations and proposed a distance of 18m.…”

The vibrations induced by moving trains especially in close distances with high-rise buildings can be destructive. The high technology of wilding rails induced a high train velocity which is associated with high vibrations. The buildings near the railways suffer from the train-induced vibrations. In this paper, a 3D FEM model was constructed to study the train-induced vibrations on a nearby high-rise building (HRB), show its response and investigate the most suitable technique to mitigate the effect of the train-induced vibrations by an open trench or a geofoam-filled trench. Three trench parameters were investigated to enhance the mitigation performance, the distance from the trench to the HRB, the trench depth and the use of either open (empty) trench or geofoam-filled trench. The geofoam-filled trench technique improved the dynamic response of the structure. Thus, trenches filled with geofoam can be considered a protection technique for high-rise buildings constructed near moving trains.

“…The railway environmental vibration has a serious impact on the human health, the structural safety of adjacent buildings, and the normal use of precision instruments. In this context, the railway environmental vibration has become a topic of great concern to international academic circles, scholars have done a lot of research on it [Xia, Cao and Roeck (2010); Zhang and Feng (2011); Hesami, Ahmadi and Ghalesari (2016)]. Some scholars have conducted experiments on the railway environmental vibration and obtained a large amount of important data.…”

The railway environmental vibration caused by high-speed railways is harmful to the human health, the structural safety of adjacent buildings, and the normal use of precision instruments. At the same time, it occurs frequently. In this case, the railway environmental vibration has drawn much attention with the rapid development of highspeed railways. Studies in Earthquake Engineering show that a convex topography has a great impact on ground vibrations, however, there is no consideration about the convex topographic effect in the study of the railway environmental vibration when the convex topography is near the roadway. In this paper, the influence of a convex topography on the railway environmental vibration was investigated. Two-dimensional (2D) finite element models consist of subgrade-convex topography and subgrade-flat topography are established using the finite element method. The length and the height of the analysis model are taken as 200 m and 41.3 m, respectively. The external soil of the calculation model is simulated via the artificial boundary. By comparison with measured results, the 2D finite element models were verified to be effective. The convex topographic effect is studied by conducting parameter investigations, such as the bottom width, cross-sectional shape, height-width ratio and the foundation soil properties. Results show that the dimension and cross-section shape of the convex topography and the foundation soil properties have significant effect on the convex topographic effect.

“…Franc¸ois et al 21 discussed the coupling of the FE and BE methods to obtain solutions for transient dynamic soil-structure interaction problems in the time domain. Hesami et al 22 studied the vibration of a building near a train line using a numerical model. Prediction models were established based on the three parts, and 2D and 3D FE models are the main prediction model types.…”

This study established the transfer laws of vibration waves in a linear system under simple harmonic loading. Then, a method based on multipoint delivery in the frequency domain was proposed to predict the vibrations of historical timber buildings induced by traffic loads, in which the transfer function between two delivery points of different single frequencies is obtained. Finally, the vibration responses of the Feiyun pavilion induced by traffic loads were predicted and compared with experimental field test results. The results indicate that the predicted vibration responses and experimental field tests at the measurement point in the Feiyun pavilion correspond well in the concerned frequency bands and that the proposed prediction method can be used to predict the structural vibration responses under the influence of complex traffic loads.
