Structural Analysis of Huaguangtan Arch Dam Based on Data Assimilation Parametric Inversion by LIN Xianzhi, LUO Zenghong, XU Zheng, MIN Jiesheng, CAO Chuanbo, ZHAO Quan

“…Aiming at the difficulty of the accurate safety assessment of the overall structural state of Huaguangtan Arch Dam,a finite element model of the arch dam is established,and the data assimilation algorithm is used to invert the material parameters based on the results of the sensitivity analysis of the mechanical parameters of the arch dam concrete and bedrock.Finally,the material parameters of finite element calculation are calibrated by parameter inversion results.The results show that the residual between the finite element displacement simulation result and the monitoring data conforms to the Gaussian distribution,and its standard deviation after data assimilation parametric inversion is reduced by 81.2%,which improves the accuracy of finite element calculation.This method enables automated operation and provides a reasonable and reliable new idea for the structural safety assessment of arch dams.…”

Structure and properties forming in ductile iron during isothermal hardening using ultrasound by M. S. Kovalko, A. T. Volochko, A. V. Ziziko, V. V. Rubanik

“…The mechanical properties and structure of the treated cast irons were determined both in the cast state and after isothermal quenching.To study the effect of ultrasonic treatment of the quenching bath on the formation of the structure and properties of highstrength cast irons during isothermal quenching, a number of comparative experiments were carried out, consisting in cooling the samples from 910 °C to 350 °C with and without the use of dynamic waves to the bath. …”

Comparison of Two Mechanics-Based Methods for Simplified Structural Analysis in Vulnerability Assessment by H. Crowley, B. Borzi, R. Pinho, M. Colombi, M. Onida

“…Until such problems can be resolved, it is worthwhile considering the mechanics of simplified analytical vulnerability assessment methods and validating this part of the methodology through comparisons with detailed structural models. This paper looks at two mechanics-based vulnerability assessment methods (DBELA and SP-BELA) and compares the nonlinear static response predicted with these methods with finite elements-based nonlinear analyses of prototype buildings. …”
