Jinping Ou’s research while affiliated with Harbin Institute of Technology and other places

... As previous research has showed, inter-module connections (IMCs) play a crucial role in the lateral behaviour of self-standing steel modular buildings [3][4][5][6]. Thus far, a lot of effort has been put into the development of fullstrength/rigid inter-module joints (IMJs) which demonstrate good seismic performance based on capacity design which ensures that the seismic-input energy is dissipated through the hysteresis of the steel beams [7][8][9][10]. However, the significant permanent damage developed in the volumetric module hinders its demountability and reusability, while the large residual deformations greatly affect the functionality and repairability of a steel modular building in the aftermath of an earthquake. ...

Cyclic Tests on Hybrid Inter-module Joints with High-Damping Rubber

... Mechanical analysis primarily includes calculations of deformation within the allowable range of material performance indicators under static loads, pre-tightening force parameters, and static response distributions [13][14][15]. The establishment and solution of dynamic models can be categorized into contact surface micro-tangential response models, lumped mass models for axial macroscopic vibrations, and torsional vibration dynamic models [16][17][18]. Moreover, by utilizing intuitive finite element models to simulate realistic load environments, the vibration response characteristics of bolted joints in working components can be obtained [19,20]. ...

... A quasi-static cyclic loading test were conducted in a concrete modular structure by Chen et al. (2023). A modular building from precasted module, that is cast-in-situ with other structural elements, is evaluated under the bending capacity, initial stiffness, ductility, and energy dissipation from a seismic performance point of view. ...

... Simultaneously, scholars have analyzed the mechanical properties and established dynamic models of bolted structures based on the operating conditions of bolted joints [10][11][12]. Mechanical analysis primarily includes calculations of deformation within the allowable range of material performance indicators under static loads, pre-tightening force parameters, and static response distributions [13][14][15]. The establishment and solution of dynamic models can be categorized into contact surface micro-tangential response models, lumped mass models for axial macroscopic vibrations, and torsional vibration dynamic models [16][17][18]. ...
