Indirect assessment of concrete resistance from FE model updating and Young's modulus estimation of a multi-span PSC viaduct: Experimental tests and validation

Angelo Aloisio et al.

Summary: The paper discusses the possibility of estimating concrete resistance based on Young's modulus assessed from FE model updating using ambient vibration data. The procedure is applied to a prestressed concrete bridge in Italy. The authors estimate the concrete resistance using an empirical correlation and compare it to the resistance obtained from destructive tests. The indirect method yields a good matching in terms of estimated parameters, but the variance from concrete samples is higher.

Optimal preliminary design of variable section beams criterion

Raffaele Cucuzza et al.

Summary: This paper discusses optimal shape solutions for non-prismatic planar beams, obtaining deformations and stresses through analytical and numerical methods while considering the effects of non-prismatic geometry. The study compares solutions with existing results and identifies a critical threshold for the emptying function, beyond which the arch effect and curvature of the axis cannot be neglected. The study also investigates the impact of key parameters such as beam span, emptying function level, and maximum allowable stress.

Bending Stiffness Identification of Simply Supported Girders using an Instrumented Vehicle: Full Scale Tests, Sensitivity Analysis, and Discussion

Angelo Aloisio et al.

Summary: This paper introduces an alternative testing procedure using an instrumented vehicle equipped with a swinging pendulum and laser sensor to estimate the bending stiffness in prestressed concrete bridges, reducing time and economic limitations of static load tests. Preliminary outcomes from real-case bridges testing show the feasibility of the procedure and provide confidence for further development. Sensitivity analysis based on covariance enlightens the effect of parameter uncertainties on the results, laying a basis for appropriate validation of the method.

Dynamic Characterization of Timber Floor Subassemblies: Sensitivity Analysis and Modeling Issues

Dag Pasquale Pasca et al.

Summary: This study investigated experimental testing of a lightweight timber floor using ambient vibration tests and sensitivity analysis, revealing that the longitudinal modulus of elasticity is the most critical parameter affecting floor response, while being highly dependent on boundary conditions. Automatic modal updating algorithms tuned the numerical model to test results.
