Abstract: This thesis presents numerical and experimental studies on modeling of lightweight high-strength concrete (LWHSC) under static and dynamic loadings. A new strain-based damage model is developed based on continuum damage mechanics. The proposed model incorporates the strain rate effects on various concrete properties, such as tensile and compressive strengths, critical strains and elastic moduli. In the numerical analysis, the model is incorporated as a material subroutine in a well-established finite element software. In the experimental investigation program, both static and impact tests were carried out for two types of LWHSC to verify the model. Published experimental results for normal weight concrete (NWC) under different loading conditions were also used to substantiate the proposed model. Comparison between the numerical and experimental results shows that the proposed constitutive relationship is sufficiently accurate to model LWHSC as well as NWC under both static and impact loading.
