TL;DR: A method for estimating the damage intensities of joints for truss bridge structures using a back-propagation based neural network and the natural frequencies and mode shapes were used as input parameters for damage identification.

TL;DR: In this paper, an analytical approach for crack identification procedure in uniform beams with an open edge crack, based on bending vibration measurements, is developed, where the cracked beam is modeled as two segments connected by a rotational mass-less linear elastic spring with sectional flexibility, and each segment of the continuous beam is assumed to obey Timoshenko beam theory.

TL;DR: In this paper, the numerical seismic response of liquid storage tanks isolated by bilinear hysteretic bearing elements is investigated under long-period ground motions in this research, and the authors concluded that with the installation of this type of base-isolation system, the dynamic response of tanks during seismic ground motions can be considerably reduced.

TL;DR: In this article, a new method for analysis of bonded connections of CFRP and steel substrates is presented, where simple closed-form solutions are derived to calculate total elastic stiffness as well as effective elastic bond length of a plate bonded to a rigid substrate.

TL;DR: In this paper, the effects of base-isolation on the seismic response of cylindrical vertical flexible liquid storage tanks subjected to horizontal seismic ground motion are presented in the time domain.
