Abstract: The traditional fiber beam model has been extensively used to simulate the dynamic behavior of components and analyze the progressive collapse resistance performance of building structures. However, this model overlooks ...

Abstract: Based on advanced numerical simulation technology, a complex finite-element model of a fragment and slab is constructed using software LS-DYNA version 971. A series of numerical simulation analyses are conducted on this ...

Abstract: The primary objective of this study was to investigate the constitutive relations and damage properties of concrete in complex stress states with different stress paths under high pressure. Monotonic hydrostatic pressure, ...

Abstract: Existing research indicates that free water has a considerable influence on the dynamic mechanical properties of concrete, which is not considered in commonly used concrete models. This paper presents a high-fidelity ...

Abstract: Blast loads acting on structural components under close-in explosions are nonuniform; therefore, the damage to structural members under such blast loads is local and the failure mechanism is more complex as compared with ...

Abstract: Almost all of the available test data for pressure–volumetric strain curves [equations of state (EoS)] of concrete are based on static triaxial tests and one-dimensional impact tests, for example, the flyer-plate impact ...

Abstract: This paper experimentally investigates the influence of saturation on dynamic behaviors of concrete under both tension and compression stress states. Two grades of concrete were saturated to 0%, 50%, and 100% by oven drying ...
