“…• The type of the finite element formulation and the numerical model are important factors during sensitivity analysis of concrete structures [228][229][230][231][232][233]. Depending on the numerical modeling strategy, e.g., lumped plasticity, distributed plasticity, or detailed finite element model, the outcome of sensitivity analysis alters.…”

Sensitivity analysis is a crucial step in computational mechanics and earthquake engineering. Sensitivity analysis of a model (either numerical or physical) aims at quantifying the relative importance of each input parameter, their potential interaction, and their effects on the model response. Sensitivity analysis has a long-term application in structural engineering more specifically on reinforced concrete RC structures. Many researchers benefited from the results of sensitivity analysis to reduce the uncertainty domain to those variables which are very important. This further helps in uncertainty quantification by accelerating the entire process. This state-of-the-art technical report provides a comprehensive review of classical sensitivity analysis techniques, followed by an in-depth review of all the related documents that implemented a full sensitivity analysis or partially adopted it for uncertainty quantification-related discussions. This review report on sensitivity analysis of reinforced concrete structures is a valuable contribution to the field of computational mechanics and earthquake engineering. This review highlights the importance of selecting an appropriate sensitivity analysis technique to achieve reliable results in structural analysis and design. By providing insights into the advantages and limitations of various sensitivity analysis techniques, this report can guide researchers, practitioners, and decision-makers in selecting the most appropriate technique for their specific applications. It is observed that the outcome of a sensitivity analysis depends heavily on the applied technique to perform the sensitivity assessment which eventually may cause a significant bias during the decision making. This report paves the road for better selection of a sensitivity analysis technique in problems related to structural and earthquake engineering. The findings of this review have significant implications for improving the accuracy and reliability of structural analysis, ultimately leading to safer and more resilient structures.

SUMMARY Recently, the structure, function, stability, and dynamics of subcellular structures, organelles, and multi-protein complexes have emerged as a leading interest in structural biology. Geometric modeling not only provides visualizations of shapes for large biomolecular complexes but also fills the gap between structural information and theoretical modeling, and enables the understanding of function, stability, and dynamics. This paper introduces a suite of computational tools for volumetric data processing, information extraction, surface mesh rendering, geometric measurement, and curvature estimation of biomolecular complexes. Particular emphasis is given to the modeling of cryo-electron microscopy data. Lagrangian-triangle meshes are employed for the surface presentation. On the basis of this representation, algorithms are developed for surface area and surface-enclosed volume calculation, and curvature estimation. Methods for volumetric meshing have also been presented. Because the technological development in computer science and mathematics has led to multiple choices at each stage of the geometric modeling, we discuss the rationales in the design and selection of various algorithms. Analytical models are designed to test the computational accuracy and convergence of proposed algorithms. Finally, we select a set of six cryo-electron microscopy data representing typical subcellular complexes to demonstrate the efficacy of the proposed algorithms in handling biomolecular surfaces and explore their capability of geometric characterization of binding targets. This paper offers a comprehensive protocol for the geometric modeling of subcellular structures, organelles, and multiprotein complexes.
