“…Recently, structural reliability analyses have allowed significant progress in the conception phases and for maintenance programs through a more rational estimation of the risk exposure. Moreover, reliability analysis works carried by Frangopol et al [20,21] and Milton [22] out on reinforced concrete columns have showed the importance of the load path, the load correlation and random variables of concrete in the reliability assessment.…”

A new concrete-composite beam with high mechanical performances to weight ratio is developed in this study. The proposed design technique consists to embed a cylindrical polymer tube wrapped by a GFRP Jacket in the mechanically ineffective concrete tensile zone. An experimental investigation is carried out on composite beams under bending loads until failure to evaluate the flexural capacity and the corresponding failure mechanisms. Based on the experimental results, statistical and preliminary reliability analyses using the FORM method are performed to assess the safety margin of the new beam. The confrontation between test and simulation results shows a satisfactory agreement, and represents a promising revelation regarding the improvement in terms of strength and ductility of such design compared to conventional reinforced concrete beams with traditional one.

“…The highest flood level since the dam was in service is 1129.74m, which is 0.74m higher than the check flood level, so it is rather important to review the actual operation condition and to analyze the sensitivity of the dam to water level, for ensuring the safe operation of the dam. As of now, there is not yet any unified standard available for the material constitutive model in the numerical computation for gravity dam, and thus we should do some further researches on the choices of material constitutive models when we do numerical simulation, especially three-dimensional numerical simulation [1][2][3][4][5][6]. For this dam, the bedrock is well preserved, so is the geological condition; but it still needs to be confirmed whether or not it is proper to use elastic material in the numerical modeling for the dam.…”

A new method that 3D numerical simulation combined with anti-cut stability analysis is employed to analyze the stability of Majiabian gravity dam, and the results of the analysis conform to the measured value. And this method can be used in analysis of congener gravity dam. When the results of 2D sliding stability analysis satisfy Code’s requirements, elastic material can be used in 3D numerical simulation. The results of water level sensitivity analysis and deformation modulus of its foundation sensitivity analysis indicates that this gravity dam is insensitive to water level; grouting method can be adopted to enhance its foundation. The results of abutment under tension stress analysis indicate that tension stress of abutment must be considered in high gravity dam design, and arch can be used for reducing the tension stress.
