Research

Dr Bi's current research interests mainly focus on the following parts:

Pipeline vibration control

Pipelines are important lifeline structures but are vulnerable to different types of damages. These damages are often associated with pipeline vibrations. Therefore, it is important to control these adverse vibrations to reduce the possible catastrophic damages.

Pounding responses and damage simulation of adjacent engineering structures

Pounding induced damages to engineering structures were repeatedly onserved in previous major earthquakes. Most of previous studies only consider point-to-point poundings. In reality, pounding could occur along the entire surfaces of the adjacent structures. Moreover, spatially varying ground motions may generate torsional responses of engineering structures and may cause eccentric poundings. 3D surface to surface and eccentric poundings are numerically simulated and damage mechanism is examined.

Modeling and simulation of spatially varying ground motions

An approximate method to model and simulate spatially varying ground motions on the surface of uneven sites with non-uniform soil conditions was proposed. This method combines the one-dimensional wave propagation method with spectral representational method. It can be used to conveniently consider the influence of local site effect on the ground motion spatial variations.

Progressive collapse of engineering structures

Progressive collapse is the most dramatic and feared form of failure in structural engineering. It usually occurs unexpectedly and causes high losses. It is important to understand the nature of progressive collapse.
