Seismic damage assessment of subway station subjected to mainshock-aftershock sequences
Yantu gongcheng xuebao, 2023 In the previous seismic analyses of underground structures, only the peak structural response under the main earthquake is considered, but the damage mechanism of underground structures subjected to sequential ground motions has not been fully understood

Effects of Ground Motion Directionality on the Seismic Behavior of Mid-rise Concrete Buildings with Considering Unequal Live-Load Distribution in Height [PDF]
Journal of Rehabilitation in Civil Engineering, 2018 The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings.

Seismic Retrofitting of Steel Frames with Buckling Restrained and Ordinary Concentrically Bracing Systems with Various Strain Hardening and Slenderness Ratios [PDF]
Journal of Rehabilitation in Civil Engineering, 2014 The present study assesses the seismic performance of steel moment resisting frames (SMFs) retrofitted with different bracing systems. Two structural configurations were utilized: ordinary concentrically braces (OCBFs), buckling-restrained braces (BRBFs).

Inter-Story Drift Ratio Detection of High-Rise Buildings Based on Ambient Noise Recordings
Applied Sciences, 2023 The inter-story drift ratio (IDR) is a crucial parameter in structural health monitoring to judge the safety, stability, and serviceability of buildings. Real-time, continuous, and widely applicable detection on IDRs is essential. However, the current methods present some challenges in conducting such detection, including adverse effects from weather ...
