  • Low-damage earthquake-resilient structural systems

      低损伤韧性抗震结构体系：自复位、摇摆、可更换等低损伤高性能抗震结构

The current seismic design philosophy aims to ensure the performance objectives (i.e., life safety and collapse prevention) of structures by dissipating energy in carefully selected “sacrificial” regions (e.g., plastic hinges) during severe earthquakes. However, severe damage accompanied by considerable residual (permanent) deformation commonly requires costly repair, or even demolition, after strong earthquakes, thereby resulting in significant socioeconomic losses in terms of building reconstruction and occupation downtime. These recent earthquakes indicate that the current seismic design concept does not consider rapid recovery of normal serviceability after a severe earthquake and cannot meet the requirements for resilience and sustainability of modern societies. The research topic of our group is to develop high-performance low-damage earthquake resilient structural systems to address the above problems.

  • Applications of shape memory alloys (SMAs) in Earthquake Engineering
    高性能金属材料形状记忆合金：超弹性耐腐蚀镍钛合金等材料面向地震工程应用

Shape memory alloys (SMAs) are high-performance metallic materials that can undergo considerable strains and recover their initial shape through heating (shape memory effect) or unloading (superelastic effect). The superelasticity of SMAs is particularly attractive to the field of earthquake engineering because of its inherent flag-shaped hysteretic loops, which are associated with minimal residual deformation under cyclic loading. Moreover, the excellent corrosion-resistance performance and high fatigue resistance of nickel–titanium (NiTi) SMAs can overcome the aging, durability, and maintenance issues in the life cycle of civil infrastructure.

  • Seismic performance of reinforced concrete and steel structures

      钢筋混凝土结构与钢结构：钢筋混凝土和钢结构体系地震损伤控制与性能评估

Reinforced concrete structures and steel structures are widely used in low- and high-rise buildings constructed in seismic regions due to their high lateral stiffness and strength. A current focus on earthquake engineering research and practice is the development of performance-based seismic design (PBSD). As accepted generally by the researchers of structural engineering, PBSD method provides a promising solution for the design of seismic-resistant structures. The PBSD aims to improve structural engineering by providing engineers with the capability of designing structures to achieve a variety of seismic performance levels, and it allows structures to experience damage to a certain extent during earthquakes, which necessitates making the definition of certain damage levels corresponding to the different performance level of structures.

  • High-performance passive dampers and base isolation bearings

      高性能减隔震装置与体系：自复位支撑、阻尼器、隔震支座等装置性能评估

Metallic dampers are one of the most effective energy dissipating devices to mitigate the earthquake response of structures. A variety of passive dampers have been developed and widely used in the high seismicity regions due to the ease of manufacturing and installation and the properties of stability and robustness. Metallic dampers exhibit fat hysteresis loops with excellent energy dissipation capability. Consequently, these metallic dampers can protect the main structures under earthquake shakings, which is a desirable characteristic in the conventional seismic design philosophy. However, the inherent inelastic deformation of the metallic dampers, in turn, results in apparent damage accompanied by a large range of permanent deformation after unloading. Structures designed with these metallic dampers, particularly with low post-yield stiffness, are vulnerable to residual drift after strong earthquakes.

  • Seismic performance and retrofitting of non-seismically designed existing structures

      地震区非延性既有结构：新型加固技术与结构体系性能提升

Seismic safety of a large number of existing non-seismically designed reinforced concrete structures is a major concern around the world. Evidence from past earthquake reconnaissance demonstrated that non-seismically designed RC buildings are vulnerable to substantial damage or even collapse under moderate to severe earthquakes. Non-seismically designed structures mainly feature inadequate reinforcement details, such as a lack of joint transverse reinforcement, insufficient transverse reinforcement in columns, column lap splice located in potential plastic hinge regions, and inadequate anchorage detailing.
