Experimental and Seismic Response Study of Laminated Rubber Bearings Considering Different Friction Interfaces

Autor: Bingzhe Zhang, Kehai Wang, Guanya Lu, Wenhua Qiu, Weitao Yin

Publikováno v: Buildings, Vol 12, Iss 10, p 1526 (2022)

Unbonded LRBs (laminated rubber bearings) are commonly applied in small-to-medium-span bridges in China. The frictional sliding characteristics of LRBs have a vital influence on the seismic response of the bridge. Nine square LRBs were subjected to t

Fragility-Based Improvement of System Seismic Performance for Long-Span Suspension Bridges

Autor: Guanya Lu, Kehai Wang, Wenhua Qiu

Publikováno v: Advances in Civil Engineering, Vol 2020 (2020)

In this study, a procedure is developed to evaluate and improve the seismic performance of long-span suspension bridges based on the performance objectives under the fragility function framework. A common type of suspension bridge in China was utiliz

Analysis of the Seismic Behavior of a Wall Pier of a Covered Bridge Based on the Multi-Layer Shell Element

Autor: Wenhua Qiu, Kehai Wang, Weitao Yin

Publikováno v: Applied Sciences, Vol 12, Iss 7, p 3499 (2022)

To investigate the seismic behavior of the wall pier of a covered bridge, the multi-layer shell element in OpenSEES was used to carry out the numerical analysis under a horizontal low cyclic loading in the weak axis direction. The effects of the mesh

Reducibility for a Class of Almost-Periodic Differential Equations with Degenerate Equilibrium Point under Small Almost-Periodic Perturbations

Autor: Wenhua Qiu, Jianguo Si

Publikováno v: Abstract and Applied Analysis, Vol 2013 (2013)

This paper focuses on almost-periodic time-dependent perturbations of an almost-periodic differential equation near the degenerate equilibrium point. Using the KAM method, the perturbed equation can be reduced to a suitable normal form with zero as e
