TL;DR: In this paper, a 3D viscous-spring artificial boundary (VSAB) in the time domain is proposed for dynamic soil-structure interaction problems, which can be conveniently incorporated in the general finite element program.

TL;DR: In this paper, a field investigation was carried out in the strongly affected areas and over 320 bridges were examined, and the most common damage included shear-flexural failure of the pier columns, expansion joint failure, shear key failure, and girder sliding in the transversal or longitudinal directions.

TL;DR: In this article, a series of shaking table tests were conducted based on a plaster model of a three-story and three-span subway station, and the dynamic responses of the structure and ground soil under main shock and aftershock ground motions were studied.

TL;DR: Compared to the conventional TMD system, the static stretching of the spring due to gravity and the oscillation amplitude of the mass block in the TMDI system are significantly reduced, which makes the proposed T MDI system an attractive alternative for the VIV control of long-span bridges.

TL;DR: In this article, the authors deduced the formulas of equivalent nodal forces for the 2-D plane P waves with arbitrary incident angles and implemented them into the commercial software ABAQUS.
