Advances in Seismic Performance Enhancement of Building Structures

Dear Colleagues,

The ductile design principle has been widely adopted in the seismic design of structures, and therefore primary structural components are designed to have the dual functions of bearing and energy dissipation under earthquake conditions. In recent years, the intensity of the major earthquakes that have occurred in China, Chile, New Zealand and Japan have reached or exceeded the design level of the maximum credible earthquake. In most cases, the designed structures did not collapse and the casualties were small. However, many structures were seriously damaged and had to be overhauled or rebuilt, resulting in huge economic losses. Therefore, researchers have paid more attention to enhancing the seismic performance of building structures.

At present, three strategies are mainly adopted to enhance structural seismic performance: anti-seismic technology, energy dissipation technology and isolation technology. A large number of new anti-seismic structural systems, new materials and new technologies have been proposed, such as rubber isolation bearings, friction pendulum isolation bearings, viscoelastic dampers, friction dampers, rocking structures, ultra-high-performance concrete, fiber-reinforced cement-based composite material, displacement-based design methods, energy-based design methods, etc. The seismic performance enhancement of building structures has achieved great success both in research and applications in recent years. Therefore, this Special Issue plans to give an overview of the advances at the frontiers.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Anti-seismic structural systems;
• Isolation structural systems;
• Energy dissipation structural systems;
• High-performance materials;
• Seismic design method for new and existing structures;
• Structural vibration control;
• Optimum design of engineering structures;
• Evaluation methodology of structural response;
• Advanced analytical simulation and experimental testing of engineering structures.

We look forward to receiving your contributions.
