Xiaolan Liu, Zhihua Chen, Fengheng Zhu, Hao Chen
TL;DR
This study examines how aircraft hangar structures respond to different loads, identifying key stress points and offering design improvements for safer, more efficient hangars.
Contribution
The paper introduces a numerical model to analyze the structural behavior of hangars under multiple load combinations, revealing critical stress and displacement patterns.
Findings
Maximum compression occurs at the upper section of the two main trusses, while maximum tension appears at the mid-span of the lower inner truss.
Roof mid-span displacement is greater than at the edges, and the main truss displacement exceeds that of the secondary truss.
The first three vibration modes significantly influence the structure’s seismic response and are highly susceptible to excitation.
Abstract
To analyze the collaborative work performance of the roof structure and the lower support structure for the aircraft maintenance hangar, a numerical model of a single-span aircraft maintenance hangar is established to study the static and dynamic mechanical responses under various load combinations. Results show that the primary axial force and bending moment responses are concentrated in the main truss and the lower support column. The maximum compression occurs at the upper section of the two main trusses, while the maximum tension appears at the mid-span of the lower inner truss near the hangar gate. The displacement of the main truss exceeds that of the secondary truss, with the roof’s mid-span displacement being greater than that at the edges. The maximum support reactions occur at the main truss support column, the secondary truss column of the rear gable wall, and the lateral…
