TL;DR: In this paper, the authors presented the pseudo-dynamic analysis to determine the seismic vertical uplift capacity of a horizontal strip anchor using upper bound limit analysis, where the real dynamic nature of earthquake accelerations cannot be considered.

TL;DR: In this article, the relationship between the tension and geometry of the embedded line, and the interactional equation between the anchor and embedded line is derived, which can be used to predict the anchor trajectory.

TL;DR: In this paper, a simple and fast evaluation method of soil-structure interaction (SSI) effects of embedded structures via a cone model is presented via the evaluation of the impedances and the effective input motions at the bottom of an embedded foundation.

TL;DR: In this article, free and forced vertical vibration tests were conducted on surface and embedded models for footings on dry and moist poorly graded sand that has the following properties: D10 = 0·21 mm, D30 = 0.305 mm,D60 = 0 ·423 mm, Cu = 2, Cc = 1·05, Gs = 2·66, γmax = 1.74 cm−3 and γmin = 1 ·4 g cm −3.

TL;DR: In this article, the horizontal shear resistance of the connection between full-depth precast concrete bridge deck panels and prestressed concrete girders was investigated. And the authors concluded that the one presented in the AASHTO LRFD Bridge Design Specifications is the best predictor of the strength of the specimens.
Abstract: This article reports on a study of the horizontal shear resistance of the connection between full-depth precast concrete bridge deck panels and prestressed concrete girders. This connection consists of isolated shear connectors extending from the precast I-girder into a block-out pocket in the precast deck panel. The blockouts and the haunch between the panel and the beam are grouted. In the study, 36 push-off tests were performed to investigate the strength and behavior of the connections. The factors investigated included type of grout, haunch height, and area of reinforcing steel crossing the interface. In addition, several alternate shear connector details were tested. Results showed that there was no significant difference in peak shear stress between specimens with 1, 2, and 3 in. haunch heights. The extended stirrups must be detailed to have a minimum of 5 in. embedment into the deck panel. The alternate shear connectors in this study are viable for use with the precast panel system. Proper embedment and spacing of connectors will ensure yielding of the steel and ductile behavior of the interface. The authors conclude that, of currently known horizontal shear resistance equations, the one presented in the AASHTO LRFD Bridge Design Specifications is the best predictor of the strength of the specimens.
