RISA Novel Beam–Column Component Macromodel for the Degradation Mechanism Analysis of RC Structures Subjected to Blast Loading
Publisher: American Society of Civil Engineers
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 ...
Reliability Analysis of RC Columns and Frame with FRP Strengthening Subjected to Explosive Loads
Publisher: American Society of Civil Engineers
Abstract: Some structures, both military and civilian, might experience explosive loads during their service life. Owing to high uncertainties in blast load predictions and structural parameters, accurate assessment of the performances ...
Reliability Analysis of RC Columns and Frame with FRP Strengthening Subjected to Explosive Loads
Publisher: American Society of Civil Engineers
Abstract: Some structures, both military and civilian, might experience explosive loads during their service life. Owing to high uncertainties in blast load predictions and structural parameters, accurate assessment of the performances ...
Development of a Concrete Constitutive Model Considering Free Water Effect for Predicting Dynamic Responses of Concrete Structures
Publisher: ASCE
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 ...
Failure Analysis and Damage Assessment of RC Columns under Close-In Explosions
Publisher: American Society of Civil Engineers
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 ...
Experimental Studies on Mitigating Local Damage and Fragments of Unreinforced Masonry Wall under Close-in Explosions
Publisher: American Society of Civil Engineers
Abstract: Debris hazard causes most of the casualties and injuries in terrorist or accidental explosions. It is defined as high-velocity fragments originating from structural components and building envelope systems induced by a ...
Volumetric Properties of Concrete under True Triaxial Dynamic Compressive Loadings
Publisher: American Society of Civil Engineers
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 ...
Influence of Water Saturation on Dynamic Tensile and Compressive Behaviors of Concrete
Publisher: ASCE
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 ...
Effect of Stress Path on the Damage Properties of Concrete under High Pressure
Publisher: ASCE
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, ...
