TL;DR: In this article, an empirical formula for determining the 3D aerodynamic admittance of a streamlined bridge deck is proposed based on the extensive results of the experimental data and analysis, and the correlation between the fluctuating pressures on a crosswise section and the coherences of the buffeting force along the spanwise direction of the models are investigated.

TL;DR: In this article, field measurements of wind effects on a 420-meter-high supertall building in Hong Kong were analyzed during the passages of 14 tropical cyclone (TC) events, from 2008 to 2016, with a total...

TL;DR: In this article, a finite segment model is developed to calculate the shear lag effects for box girders with varying depth, where multiple longitudinal displacement functions are used to derive stiffness matrix and the nodal force vector of the segment element.

TL;DR: In this article, a new exact approach for free vibration analysis of a multi-step beam with an arbitrary number of cracks and concentrated masses is proposed, where a model of massless rotational spring is adopted to describe the local flexibility induced by cracks in the beam.

TL;DR: In this paper, a large negative magnetic anomaly occurs around Qingchuan-Wenchuan-Guanxian and Guanxian-Beichuan segments in the northern Longmenshan fault zone, which corresponds to the location of the horizontal gradient belt of the residual gravity anomaly.
