Abstract: The instability of structural members under axial compression most likely causes spatial structural collapse. Therefore, the configuration of double-layer members (DLMs) is proposed in this study to improve the stability ...

Abstract: Long-span, single-layer spatial grid structures are widely used in public buildings. The progressive collapse of such structures could cause great losses of property and human life. To accurately capture the performance ...

Abstract: A dynamic experiment of progressive collapse constitutes the basis of a collapse-resistant analysis. To achieve broad applicability and avoid superfluous influencing factors, two representative substructures extracted from ...
