Soil is treated as a mixture composed by three phases: soil particles, water, and air. Numerical methods have been developed to simulate infinitesimal and large deformation, failure, and dynamic response based on mechanics and dynamics of these interrelated phases. Hence, such numerical analyses inherently resolve the problems of multi-physics. Recently, plant roots and oils are also occasionally included in the solid and liquid phases to investigate the effect of the vegetation on slope stability, exploitation of natural resources, and so on. With the threat of severe rainstorms or flooding due to climate change and mega-earthquakes, disaster prevention and mitigation for soil structures or the ground are important applications of the numerical methods for the mixture of three phases.

This mini-symposium is intended to discuss the development of novel structural optimization methods for creating a better society. Now, we are surrounded by a lot of functional devices and artifacts, which play important roles for improving our quality of life, and their performances often strongly depend on their own structures. On the other hand, designing structural shape and topology of those devices and artifacts is a difficult task for designers because they must find a satisfactory solution in a large design space while considering many requirements. Structural optimization, which is roughly classified into sizing, shape, and topology optimizations, is a promising design methodology for the above task because it can find the optimal, at least a locally optimal, solution on the basis of mathematics and physics.

MS-15: Direct Computation of Safety Margins for Structures and Materials

Konstantinos V. Spiliopoulos (National Technical University of Athens), Geng Chen (Beijing Jiatong University)

A major task for mechanical and civil engineers is to evaluate the margins of safety of limit states against any type of loading that may cause severe inelastic deformations. Typical cases of such loads are thermo-mechanical actions, wind loading, or displacement induced loads like earthquakes, traffic, etc.

Plastic collapse is a limit state which coincides with the exhaustion of the load carrying capacity. Another important limit state is ‘shakedown’, related to structures, subjected to cyclic external actions. In this state, plastic straining occurs only during the first loading cycles.

‘Direct methods’ are non-evolutionary and computationally most efficient procedures to estimate the plastic collapse or the shakedown load of a structure, as they avoid cumbersome and time-consuming step-by-step analyses. Development of efficient numerical algorithms, highly performing optimization procedures, together with the advent of computer power, make them applicable to practical engineering. Steel and more complex material models for metals, concrete, composite and soil-like material have been accounted for with applications from buildings to pavements and railways and from pressure vessels to space capsules.

The aim of this Mini-symposium is to gather scientists researching in this area, who will present its state of the art to the wide international audience of COMPSAFE25.

Key topics will include the computational simulation of cracking, fatigue, and fracture; the interaction of cementitious materials with aggressive agents (e.g., chloride ions, freeze-thaw cycles); and strategies for enhancing material performance through innovative design and material science. Special focus will be given to bridge repair and reinforcement techniques, examining cutting-edge methods for strengthening existing concrete structures, retrofitting damaged infrastructure, and assessing the long-term effectiveness of various repair and reinforcement approaches in high-risk areas.

Case studies on the application of these materials in high-risk zones, such as earthquake-prone areas, and assessments of their long-term structural behavior in extreme environmental conditions will also be welcome. This minisymposium will provide an excellent platform for knowledge exchange and foster collaboration between academia and industry, helping to advance computational methods and experimental approaches for cementitious materials in line with the objectives of COMPSAFE2025. Through these discussions, we aim to contribute to the broader goals of disaster prevention and mitigation, structural safety, and the development of resilient infrastructure networks.
