Progressive Collapse Resistance Analysis of Plate-member Composite Reticulated Shell Structure
In order to study the progressive collapse resistance of plate-member composite reticulated shell structure and propose an applicable analysis method, the complete and member removal experimental models of composite reticulated shell structure were designed by Alternate Path (AP) analysis method, and the progressive collapse resistance test and numerical analysis were carried out. The results show that the honeycomb plate contributes greatly to the bearing capacity of the composite structure, the ultimate bearing capacity of member removal structure is 3.64% smaller than that of the complete structure, and the ultimate displacement is 30% smaller. The average error of load-displacement curves between the progressive collapse resistance test and numerical analysis is less than 10% in the elastic stage, and the overall failure mode of the numerical analysis model and the experimental model is consistent. The anti-progressive collapse analysis method based on modal sensitivity is suitable for the plate-member composite reticulated shell structure due to high computational efficiency and accuracy, which provides a reference for progressive collapse resistance analysis of plate-member composite reticulated shell structure.
