progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

Abstract The perovskite solar cell (PSC) is one of the most promising photovoltaic candidates along with highly increasing demand for green electricity. One main concerns regarding PSC during its service life nonlinear instability due to ultra-thin structural features and dynamic loadings. This paper presents a framework stability analyses oblique stiffeners that are integrated as enhancements ...

This paper aims at reviewing nonlinear methods for model order reduction in structures with geometric nonlinearity, a special emphasis on the techniques based invariant manifold theory. Nonlinear differ from linear-based by their use of mapping instead adding new vectors to enlarge projection basis. Invariant manifolds have been first introduced vibration theory within context normal modes and ...

Economy and safety are two important components in structural design process and stablishing a balance between them indeed results in improved structural performance specially in large-scale structures including space lattice domes. Topology optimization of geometrically nonlinear single-layer lamella, network, and geodesic lattice domes is implemented using enhanced colliding-bodies optimizati...
