“…In particular, [7,33,35,36] revealed that rocking piers can exhibit large drifts (around 6% to 10%) with minor damage and/or residual displacements. Recent experimental studies [37,27] showed that the residual drifts of posttensioned rocking columns are negligible (0.4%) compared to the pertinent drifts of conventional monolithic columns (6.8%) with the same peak drift ratios; in accordance with [32]. Further, [19,20] showed that the stability of the rigid rocking frame is enhanced, the more heavy its cap-beam is, regardless of the rise of its center of mass; a counter-intuitive behavior.…”

Abstract. Allowing structural members to uplift and rotate around pre-defined pivot points isolates and relieves the structure from deformation and damage during strong earthquakes. Such rocking behavior has been examined as damage avoidance seismic design for bridges. Rocking structures, either freestanding or hybrid (supplemented with energy dissipation and re-centering devices), have been proposed by several researchers as high-performance systems that can survive major earthquakes without substantial damage. This paper investigates, analytically and numerically, the seismic performance of a hybrid rocking bridge bent which exhibits flag-shaped hysteretic behavior. The rocking frame is enhanced with elastic prestressed central tendons to provide re-centering capacity and hysteretic buckling restrained braces to dissipate energy. The present study examines its seismic behavior under both pulse-type and non-pulse-type ground motions. The focus of the present analysis is on the role of the prestressing force on the seismic performance. The results reveal the diverse influence of prestress. Specifically, prestress is beneficial for small rocking rotations, but could become detrimental when the frame sustains large rotations and as the size of the columns increases. Finally, the results reveal the sensitivity of the different rocking design solutions to the characteristics of the considered ground motion. As a consequence, none of the examined rocking frames can be considered as the optimal design solution under all ground motions. 4983

“…Tobolski and Restrepo (2008) and Cohagen et al (2008) used spirals with a small pitch to confine the column ends. Billington and Yoon (2004), Trono et al (2014), and Tazarv and Saiidi (2015) replaced the column ends with a fiber-reinforced concrete shell, left hollow or filled with self-consolidating concrete. Tobolski and Restrepo (2008), Restrepo et al (2011), Guerrini and Restrepo (2013), and Guerrini et al (2014) investigated columns built with a dual steel shell (with concrete cast in between the shells) designed for composite action.…”

Seismic-Resistant Precast Concrete Structures: State of the Art

et al. 2018

Precast concrete facilitates a construction method using durable and rapidly erectable prefabricated members to create costeffective and high-quality structures. In this method, the connections between the precast members as well as between the members and the foundation require special attention to ensure good seismic performance. Extensive research conducted since the 1980s has led to new precast concrete structural systems, designs, details, and techniques that are particularly suited for use in regions of high seismic hazard. This paper reviews the state of the art of these advances, including code developments and practical applications, related to four different systems: (1) moment frames; (2) structural walls; (3) floor diaphragms; and (4) bridges. It is concluded from this review that the widespread use of precast concrete in seismic regions is feasible today and that the jointed connection innovation introduced through precast research leads to improved seismic performance of building and bridge structures.dividual papers.

“…However, it remains susceptible to compression damage, including spalling of concrete cover [27][28][29]. Use of HyFRC in rocking columns has been shown to be effective in resisting compression damage at the rocking plane, improving the overall ductility of the column [13,14]. To unbond the rebar, rubber mastic tape was tightly wrapped around the bars to build thickness between the ribs such that anchorage would be negligible.…”

“…Common fiber types include polyvinyl alcohol (PVA) microfibers and hooked-end steel macrofibers. HyFRC has recently been investigated specifically for bridge column use, including static seismic testing [13] and dynamic shake table testing [14]. The experimental tests of the columns revealed significant resistances towards spalling and longitudinal rebar buckling compared to conventionally designed columns.…”
