Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...

This paper introduces a novel design concept for the development of efficient, sustainable Rocking-Wall Moment Frames (RWMFs) under seismic conditions. The proposed concepts lead to a novel structural configuration with provisions for Collapse Prevention (CP), Self-Centering (SC), reparability, performance control (PC), damage reduction, and energy based seismic analysis. It introduces the meri...

Cross-laminated bamboo (CLB) have a high strength to weight ratio and stable bidirectional mechanical properties. Inspired by the investigation on cross-laminated timber (CLT) rocking walls, CLB walls with conventional friction dampers (CFDs) are studied in this paper. To investigate properties of wall, seven tests conducted under cyclic loading scheme, different test parameters, including exis...

Allowing structures to rock during an earthquake can effectively provide base isolation at a relatively small cost. Rocking limits the shear demand and provides self-centering, but rocking response depends on energy dissipation caused by interaction with soil impacts re-centering. This paper addresses computational modeling of buildings that have either been designed beneath their foundation (f...

Cross-laminated timber (CLT) rocking walls limit internal building forces and dissipate seismic energy mostly through severe connection damage related wood crushing. While collapse-prevention life-safety performance can be achieved, the connections CLT are permanently damaged may unreliable for resisting aftershocks. Slip-friction (SFCs), also known as slotted-bolted connections, highly resilie...

Conventional concentrically-braced frame (CBF) systems have limited drift capacity before brace buckling and related damage leads to deterioration in strength and stiffness. Self-centering concentrically-braced frame (SC-CBF) systems have been developed to increase drift capacity prior to initiation of damage and minimize residual drift. SC-CBFs differ from conventional CBFs in that the SC-CBF ...

Shake table testing of a 1/5 scale model of a slender bridge steel truss pier that uses a controlled rocking approach as a means of seismic protection was conducted. The controlled rocking approach allows the pier to uplift from its base while passive energy dissipation devices steel yielding devices or fluid viscous dampers are implemented across the uplifting location to control the response....

Rocking self-centering (RSC) bridge piers were proposed based on the seismic resilience design theory, pushing development of sustainability. To develop a method for RSC piers, clear understanding their behavior under earthquakes is essential. This study analyzed whole lateral force–displacement response taking into account both rotational and flexural deformation, which resulted in clearer act...

Abstract Post-tensioned precast concrete walls are an attractive research trend in structural engineering, which replaces cast-in-place earthquake-prone buildings. Precast use mild steel and high-strength post-tensioning for flexural resistance. Mild reinforcement yields tension compression, dissipating inelastic energy. Unbounded tendons used inside the wall to give self-centering capability, ...
