Seismic resilience of retrofitted RC buildings
Springer Science and Business Media LLC - Tập 19 - Trang 561-571 - 2020
Ghazanfar Ali Anwar, You Dong
Existing buildings can be at a greater seismic risk due to non-conformance to current design codes and may require structural retrofitting to improve building performance. The performance of buildings is measured in terms of immediate consequences due to direct damage, but the continuing impacts related to recovery are not considered in seismic retrofit assessment. This paper introduces a framewor... hiện toàn bộ
Velocity adjustable TMD and numerical simulation of seismic performance
Springer Science and Business Media LLC - Tập 6 - Trang 147-158 - 2007
Li Qin, Xiyuan Zhou, Weiming Yan
A new type of velocity adjustable tuned mass damper (TMD) consisting of impulse generators and clutches is presented. The force impulse is generated by a joining operation of electromagnets and springs and MR dampers are used as clutches. Rules for velocity adjustment are established according to the working mechanism of TMD. The analysis program is developed on a VB platform. Seismic response of ... hiện toàn bộ
Discussion on “Optimum placement and characteristics of velocitydependent dampers under seismic excitation” by Seyed Amin Mousavi and Amir K. Ghorbani-Tanha

A comparative study of bridge damage due to the Wenchuan, Northridge, Loma Prieta and San Fernando earthquakes
Springer Science and Business Media LLC - Tập 8 - Trang 251-261 - 2009
Zhiqiang Wang, George C. Lee
A comparative study of selected bridge damage due to the Wenchuan, Northridge, Loma Prieta and San Fernando earthquakes is described in this paper. Typical ground motion effects considered include large ground fault displacement, liquefaction, landslide, and strong ground shaking. Issues related to falling spans, inadequate detailing for structural ductility and complex bridge configurations are d... hiện toàn bộ
A two-step unconditionally stable explicit method with controllable numerical dissipations
Springer Science and Business Media LLC - Tập 18 - Trang 285-299 - 2019
Jinze Li, Kaiping Yu, Xiangyang Li
A family of unconditionally stable direct integration algorithm with controllable numerical dissipations is proposed. The numerical properties of the new algorithms are controlled by three parameters α, β and γ. By the consistent and stability analysis, the proposed algorithms achieve the second-order accuracy and are unconditionally stable under the condition that α ≥ -0.5, β ≤ 0.5 and γ ≥ -(1+α)... hiện toàn bộ
Research on mode localization of reticulated shell structures

Numerical simulation of aerodynamic derivatives and critical wind speed for long-span bridges based on simplified steady wind field
Springer Science and Business Media LLC - Tập 6 - Trang 197-203 - 2007
Dabo Xin, Jinping Ou
Combining the computational fluid dynamics-based numerical simulation with the forced vibration technique for extraction of aerodynamic derivatives, an approach for calculating the aerodynamic derivatives and the critical flutter wind speed for long-span bridges is presented in this paper. The RNG k-ɛ turbulent model is introduced to establish the governing equations, including the continuity equa... hiện toàn bộ
Seismic fragility of flexible pipeline connections in a base isolated medical building
Springer Science and Business Media LLC - Tập 18 - Trang 903-916 - 2019
Qingxue Shang, Tao Wang, Jichao Li
Flexible pipelines are often used to connect hard pipes from a foundation to a superstructure to accommodate large deformation in the base isolation layer during an earthquake. Although Chinese seismic design guidelines suggest several configurations, they are different from the designs that have been proven in practice, e.g., Japanese styles, and extensive experimental investigation into their se... hiện toàn bộ
