TL;DR: In this paper, the authors investigated the feasibility of using the developed fiber Bragg grating sensors for structural health monitoring, via monitoring the strain of different parts of the Tsing Ma bridge under both the railway and highway loads as well as comparing the FBG sensors' performance with the conventional SWMS that has been operating at TMB since the bridge's commissioning in May 1997.

TL;DR: In this article, a solution for the vertical dynamic interaction forces between a moving vehicle and the bridge deck is analytically derived and experimentally verified, where the deck is modeled as a simply supported beam with viscous damping, and the vehicle/bridge interaction force is modelled as one point or two-point loads with fixed axle spacing, moving at constant speed.

TL;DR: In this paper, a structural model for the fatigue stress analysis of bridge-deck structures is proposed, in which structures are modeled by elastic members and welded connections with possible accumulative damage.
